How to Become a DevOps Engineer?

March 29, 2022 admin DevOps

Today, DevOps is used by most of companies and is a widely used technology. DevOps engineers are thus in greater demand in the market. In order to become a DevOps engineer, you need to possess a specific skill set and be well-versed in advanced technologies. You must understand the roles, responsibilities, and tasks of a DevOps engineer before you begin your career. You need to understand how they function within any organization and how they will benefit the company.

In this article, we will learn about DevOps methodology, the role of a DevOps engineer, the required skill set, and various tools used by them.

What is DevOps?

DevOps is a strategy or methodology that is used for the development of software. It helps in bridging the gap between the developers and the IT teams working together within the same project. It boosts up the collaboration of both teams to improve the working capabilities of both teams.

Using DevOps methodology, every organization can release small sets of features frequently and quickly. It allows the customers to provide feedback on every set and making changes to these small sets is comparatively easier than making changes to the complete software.

DevOps engineers should be able to understand the entire concept of the software development lifecycle (SDLC) and the various tools used in automating the tasks to develop continuous integration/ continuous delivery pipelines. They work closely with the developers and IT staff to monitor the software releases. DevOps engineers can be developers who are able to code, deploy, and have knowledge of network-related operations or can be system administrators who focus on testing the codes.

Explain the role of DevOps Engineer

Before moving further, it is crucial that you understand the role of a DevOps engineer and in what field they can start their career. Basically, a DevOps engineer can be both a developer or belong to the IT team.

  • Improving CI/CD pipeline- The responsibility of a DevOps engineer may vary from company to company but the main tasks will include- creating and improving the CI/CD pipeline. In short, you can say that the job of a DevOps engineer is to bring the code from the developer’s plate to the production. They will remove all the bugs and operational issues that may impact the users. Apart from this, a DevOps engineer creates automation tasks for making the deployment task easier.
  • Maintaining cloud infrastructure- Cloud computing offers you a pool of resources and services that will help in setting up the complex configurations in an efficient way. Thus it requires a DevOps engineer for managing these complex configurations. They help in managing the vast cloud infrastructure that includes- load balancers, security components, databases, and others.
  • Configuration management- A DevOps engineer requires the right set of tools for managing the configurations as they won’t be able to manage the vast enterprise-scale infrastructure. Some tools like Puppet, Chef, etc. help in defining the software and required features for each server for carrying out deployment automatically based on configuration files.
  • Monitoring- DevOps are also responsible for handling the monitoring process for detecting and minimizing the errors for customers. They help in achieving high reliability and identify the vulnerabilities that may impact the production deployment. Monitoring is a crucial part for every CI/CD pipeline to ensure effective code deployment.

Tasks and duties of a DevOps engineer

Below we have mentioned some of the tasks and responsibilities of a DevOps engineer.

  • They help in designing the required tools and processes that will help in managing infrastructure.
  • They will be able to work on several platforms along with knowledge on different programming languages.
  • They help in automating the workloads across various cloud providers.
  • They will be able to automate the process of testing and deployment.
  • They will be able to support the internal and external stakeholders on several platforms.
  • They will be able to create the required tools and processes for improving user satisfaction.

Skill Set Required to Become a DevOps Engineer

For effective working and enhanced productivity, the following skills are key for DevOps engineers.

1. Coding

Having knowledge of advanced coding might not be necessary for a DevOps engineer but it will help you to get along. But if you have knowledge of programming languages like Java, Python, etc. will help you to get into a DevOps engineer role easily. If you are good at coding then you will be able to save time, cost, and effort by optimizing the code, debugging the code, fixing deployment errors, and simplifying the development lifecycle.

Some processes in a DevOps environment like provisioning of the server, installing and configuring the required application, are automated. DevOps engineers are somehow responsible to keep these things running seamlessly. Thus they require strong coding skills to build and operate tools that will automate the DevOps process.

2. Virtualization and Cloud

Virtualization refers to the abstraction of computer systems from their physical components, allowing them to run on layers independent of the physical hardware. Virtualization breaks down the large systems by partitioning them into smaller systems, and allows multiple users or applications to use a server. Virtualization is considered to be an important part of DevOps. By virtualizing the hardware and cloning the existing systems, the development teams, IT and testing teams can work more closely for more effective results. It helps in making it possible to provision standardized environments specific for dev, test, and production systems.

Virtualization works as a core mechanism behind various clouds like public, private and hybrid clouds. A hybrid cloud is a commonly used configuration that helps in integrating the internal data centers and public cloud resources. If you virtualize the computing resources, it will handle the transition efficiently from the data center to the cloud

3. Automation Tools

Among various available DevOps automation tools, the most commonly used DevOps tools are Puppet, Kubernetes, etc. The DevOps process can be automated from code generation to build, test, and deployment. Even the testing is also automated with the right set of tools that will provide continuous feedback to development teams.

4. Testing

Considering the agile work process, organizations used to follow a step-by-step iterative process for developing applications along with a consistent link between test and development. DevOps is a one step ahead of it. Testers are not only limited to checking the functionality is working properly, but also required to test various operations, performance, security, and many other aspects of the development cycle.

Testing can be done at every stage of the software development lifecycle, from the very beginning like from planning through to coding phase and till the deployment phase.

Tools used by a DevOps Engineer

A DevOps engineer uses various advanced tools for efficient working and improving productivity. Here, we have mentioned some of the most commonly used tools in various categories.

  • Process automation tools (for example- Jenkins, Bamboo, etc.) – These help the DevOps engineers for customizing and automating delivery pipelines.
  • Source control ( for example Git) – These tools help in tracking the progress of development work, providing a version history, and creating version “branches”. Developing code in several branches is easy to be merged with the “main branch”, which can be efficiently promoted to the production environment.
  • Code repository (for example Github, Bitbucket, etc.) – It helps in integrating the source control software within the DevOps process.
  • Containerization( tools like Docker and Kubernetes) – These tools help in packaging your application along with all required configuration files and libraries, without relying on the system dependencies, into a container that can later be run as an independent application on a physical machine. A DevOps engineer is capable of handling containerized applications. Thus having the required knowledge of container principles and Docker is important.
  • Serverless software – Today most DevOps teams depend on serverless infrastructure for deploying the code in any language and scale as per the requirement, without the need to manage the actual servers. It is crucial to deploy the CI/CD pipelines and microservices applications. You can consider using the AWS serverless ecosystem. DevOps engineers must be familiar with tools like Amazon Lambda.
  • Configuration Management ( for example Puppet Enterprise, Ansible, Chef, etc.) – These tools help the DevOps engineers configure, manage, and deploy the infrastructure as code (IaC).
  • Monitoring software ( tools like Nagios, Datadog, etc.) – These tools help the DevOps teams in tracking the infrastructure, identifying the issues, and finding instant solutions for issues.
  • Project management solutions ( tools like Jira, Trello, etc.) – These are majorly adopted by the DevOps teams for managing the project items and providing work-progress-related documentation. These solutions help the DevOps team in monitoring the progress of their teams, identifying issues within the process or workflow.

Conclusion

In today’s digital enterprise, DevOps engineers play a major part. In this article, we have highlighted the main roles and responsibilities of a DevOps engineer, along with the knowledge of CI/CD pipelines, maintaining cloud infrastructure, monitoring and configuration management, and other technical skills that should be required for the position.

It requires equal contribution from all the team members who are working hard to make this possible. Make sure you understand the techniques that you are going to use. If you have a skilled team, they will understand the concept and scope of DevOps in your project.

The purpose of this article is to explain what DevOps is and how it can be beneficial for software development in any company.

Introduction to DevOps

DevOps is a methodology that is result-oriented with a mindset for constant change or improvement for creating quality products. But what does DevOps stand for? It is a combination of development and operations that refers to the complete bunch of development, IT, QA, and other teams working together in a good environment. It looks towards improving the efficiency and quality of the working process. DevOps make sure that it overcomes the IT complexities while maintaining the pace that is provided by agile methodology.

DevOps came into scope in 2009 when Patrick Debois came up with a solution for resolving the conflicts of the developers and the IT team. He reconciled both the teams and named it DevOps. It helps in bridging the gap between the developers and IT team and enhances the team collaboration to improve work efficiency. With DevOps, we can emphasize on the execution nature of developing the software while identifying common patterns of what we are doing and how. This methodology will help in minimizing the time and cost that is required to build software along with maintaining its quality.

Many companies are adapting to this approach today to increase their success and results. What were the challenges we faced with the traditional SDLC (software development life cycle) that caused us to develop DevOps as a strategy?

Challenges in Traditional SDLC

Following are some SDLC challenges that the DevOps methodology has been used to solve.

Siloed Structures and Management Bottlenecks

This traditional SDLC method breaks the software development team, the testing team, and the IT operation team into three distinct groups, each focusing on carrying out their tasks in a systematic manner but lacking communication with one another. The result would be a chaotic situation in which the developers could not discuss the code with the testing team or the operation team, which would result in unproductivity. A lack of coordination results in a long development and delivery process.

Insufficient Tests and High Probability of Errors

In traditional methodology, the tests were conducted in small units which were not enough to detect the flaws of the software or to improve the software functionality. Thus a standard and stable product could not be created. The testing team was not able to carry out continuous tests for a specific development stage as the silos are fixed for each department. Due to this, most of the time the team members face various issues like post-release bugs which could have been resolved or fixed at an early stage of the development if they carry out more tests at each stage of the software development.

Late Feedback and Lack of Transparency

As there is no communication among various teams and their members, various stages of the software development become isolated and the customer will get the output at a very late stage. Thus creating a major gap in what is expected and the final delivered product. This might require rework making the team demoralized and resulting in unproductivity. They might not cope up with the frequent complaints of the customer within the designated time. This puts a huge burden on developers and testing teams.

Late fixes and Updates

As there is a lack of communication between the developers and the IT teams, it takes time to fix the bugs and to release another update for the software. Thus the teams find it difficult to implement any change and may take time. Once you fail to deliver the product in time, you will be late forever in delivering their fixes and updates.

Benefits of DevOps

If you are a new business and thinking of how you can make a good start with fast and reliable delivery of your products, then you can use the DevOps methodology within your business. It is not only beneficial for the new business but the old and large scale business can also leverage the benefits of DevOps in their SDLC process. Below we have mentioned the benefits of using and implementing DevOps in your business.

Ensure faster deployment

Using DevOps, you can ensure timely updates and frequent delivery of your product. The only way you can satisfy your customers is to deliver their orders on time. Your business will always be one step ahead in a competitive market if you have up-to-date software.

Stabilize work environment

With DevOps, you do not have to worry about the release of the new features and updates as you will get to work in a healthy environment that will improve the team’s productivity efficiently. This will allow the team members to work with more effort with the easy and well-balanced approach for developing software.

Improves Product Quality

With DevOps, the collaboration within the project’s team increases, which improves the quality of work and fills up the communication gap. This results in improving the quality of the product. You can ask customers for timely feedback for making the required changes before the product reaches its final stage.

Automation for Effective Innovation

With DevOps, the teams will be able to detect the flaws at an early stage and fix them as soon as possible before they impact the performance of their product. If they feel that a particular failure is coming up again and again, they can perform an automated task for fixing that failure. This helps in reducing the rework of the team and they can easily focus on the development part.

Promotes Agility

If your business is agile then you can easily conquer the market and leave your competitors behind. But for that, you need to implement the DevOps methodology efficiently. Only DevOps can make it possible to obtain the scalability that will be required for transforming your business and taking it to new heights.

Continuous Software Delivery

For maintaining stability among various teams within the project, you need to go for DevOps methodology as it offers new features to your business. It makes sure that the product or the software is being developed continuously without getting any distraction. This is only possible if the team members are focused and they get a healthy working environment.

Reliable Problem-solving Methods

With DevOps, solving problems and providing fixes for bugs is reliable and efficient. As businesses get various features that they can use and implement within the SDLC process for making the tasks easier.

Conclusion

There is no doubt about the benefits that you will get with the implementation of DevOps. It has been widely adapted and popular among various companies globally. DevOps enables you to bridge the gap between the developers and IT team which was not possible using the traditional methodologies like agile. With DevOps, teams can focus on their specific tasks along with discussing it with other teams to be on the same page and to improve the functionality of the product. Whether you are a small or large business, DevOps has proved to be beneficial for everyone at every stage of the business.

Today DevOps is considered to be the latest buzzword in the market due to immense benefits offered and how it has changed the SDLC process. Unlike the traditional software development approach like Agile, DevOps majorly focuses on the collaboration of the development and the operational teams. As it has been widely adopted by many organizations in the last few years, it has led to the rise in the demand for DevOps engineers for managing and improving the software development process.

If you are looking for DevOps engineer roles then you need to understand its concept, required skills, resources, and various points so you can excel in implementing the DevOps approach. In this article, we will be highlighting the most frequently asked DevOps questions that are suitable for interviews.

Introduction to DevOps.

DevOps is a software development methodology that is considered as the combination of development and operations. It is an extension of the Agile methodology with its focus on bringing together various teams together for developing the product. It emphasizes team collaboration for improving the productivity and performance of the team members. This approach helps in automating the various processes of software development for delivering an efficient and high-quality product. It allows the team to deliver the product faster and resolve the issues at the early stage by getting feedback from customers.

How is DevOps different from Agile Methodology?

Agile is the conventional approach that was used for all software development. It focuses on the iterative, incremental, and rapid software releases along with getting feedback from the customers on each iteration. It helps in bridging the gap between the customer and the developer.

While you can say that DevOps is an advanced version of Agile, its main focus is on increasing communication with the team for better productivity. Various teams come together for continuous development, testing, deployment, and monitoring of the SDLC pipeline. The main objective of DevOps is to set equal responsibilities for the development and the operational team to eliminate the conflict between them so they can work for the improvement of the product.

Explain different Phases of DevOps.

DevOps has various phases as explained below.

  • Plan- first step is to set up a plan for what type of application needs to be developed and to create a rough picture of how the development will take place.
  • Code- at this phase, the development team works on code as per the client’s requirement.
  • Build- at this phase, various codes are integrated to create an application.
  • Test- it is considered to be the crucial stage where we look for possible bottlenecks and try to eliminate them and rework some parts if required.
  • Integrate- at this phase, we merge the codes from various developers in the team to merge functionalities.
  • Deploy- now, the code is ready to be deployed on the desired environment.
  • Operate- In this phase post deployment, developers can make changes as per the changing demand.
  • Monitor- at this stage, teams monitor the performance of the application and make the required changes to make it more efficient.

Mention the Benefits of DevOps

We have mentioned some of the benefits of DevOps.

  • It ensures faster software deployment.
  • It helps in stabilizing the work environment.
  • This methodology will improve the quality of the product.

  • It results in customer satisfaction by providing a high-quality product.

Explain the difference between continuous delivery and continuous deployment?

Continuous Delivery Continuous Deployment
It focuses on the code to be safely deployed to the production environment. It ensures that each change will pass the automated tests to be deployed to production automatically.
It makes sure that the business applications and services will function as expected. It helps in making the software development and the release process faster.
It helps in delivering every change to a production-like environment via rigorous automated testing. There is no need for approval from a developer for making changes.

Explain the role of Continuous Management in DevOps.

Below are some roles of continuous management in DevOps.

  • Disaster recovery- with the help of continuous management, you will be able to recover your assets during any disaster. It allows you to roll back the changes if it breaks down the application and go back to the state before the change.
  • Uptime and Site reliability- with continuous management, you will be able to manage the downtime and site reliability. It makes sure that there is minimum downtime due to deployment errors.
  • Easier scaling- with the help of configuration management, you can evaluate the state of your services. It also allows you to scale them as per the changing request / demand without any failure.

Explain the Role of Continuous Monitoring.

DevOps supports continuous monitoring which helps in detecting, identifying, and reporting any error in the entire infrastructure. It helps in ensuring that all the services and applications are running efficiently on the servers. Itl monitors the status of the server. It also conducts continuous auditing of the system to make the required changes.

Explain Continuous Integration in DevOps.

Continuous Integration is a DevOps practice that allows the developers to integrate their code into a shared repository. All integration is verified using the automated build process for easy error detection in their codes. Having a repository allows the developers to check their code and work on the features assigned to them. After working on the code, they are pushed to the remote shared repository which is handled by effective version control tools like Git. The CI server monitors the changes and pulls them as soon as it detects them. After pulling the changes, the CI server will trigger the code build for running tests. The results of the tests are sent to teams so that they can rework in case of failure.

Explain Continuous Testing in DevOps.

DevOps supports continuous testing that allows the teams to run automated test cases to get immediate feedback on the product quality and for validating the business risks that are associated with the automated code builds. This phase enables the team to test each build continuously to give instant feedback to the developer team so that these changes will not reach the later stages of development. This leads to the efficient development and testing process to create a high-quality product.

Explain the Benefits of Automation testing.

Test automation helps in improving the overall efficiency and quality of the software. You can use specific tools for effectively executing automated test cases and then comparing actual and expected results. Thus, test automation ensures software proficiency without any manual intervention. Below we have mentioned the benefits of the automation testing process.

  • It helps in getting faster feedback to make any required changes to the code. Then the change is tested using automated test cases.
  • It helps in saving the time spent by the team in repeatedly validating the new features.
  • It helps in improving the team communication so they can work closely with the development and deployment of the test cases.

How to Automate Testing in DevOps?

In DevOps, developers commit all the changes made in the source code to a shared repository. Then Continuous Integration tools like Jenkins pushes the changed code from this shared repository and deploy it for Continuous Testing using tools like Selenium. It allows testing every code change continuously.

What are the Principles of DevOps?

You must understand the basic principles of DevOps before implementing them within your organization. Below we have mentioned some DevOps principles for better understanding.

  • It focuses on team collaboration for improving the productivity and performance of various teams.
  • It sets the same responsibilities for various teams so they can focus towards the development and improvement of the product by eliminating the chance of blame game.
  • It focuses on minimizing the cost of failure as it ensures continuous development, testing, and management.
  • It focuses on automating every task and process within the organization for effective working.
  • It works mainly for the improvement of the product.

Version control system- DevOps interview questions

Explain Version Control.

It is a system that helps in recording the changes to files or code so that you can refer to a specific version in the future. It has a central shared repository that is used by the teammates for committing desired changes to the file. Version control helps the team to revert the entire project to its previous stage before the change was implemented. It allows you to compare the changes over time. Using version control, you will be able to know who made the last changes and what impact they had on the system.

Explain the Benefits of Version Control.

Below are some benefits that you will get using the Version control.

  • Version control system (VCS) allows the team to work and make changes to any file at any time. Later, you can merge all the changes in a single version.
  • Every version is efficiently stored at the VCS and you can request any of the stored versions and you can implement that version to your system instantly.
  • While saving any version, you can provide a name describing what change has been made to it. So that any developer can refer to it to see the desired changes.

What are the Branching Strategies in VCS?

You can use any of the below-mentioned branching strategies in VCS.

  • Feature branching- this type of branching will keep all the changes related to a specific feature inside a branch. Once the feature is completely validated and tested then it is merged to the main branch.
  • Task branching- this type of branching allows implementing each task in its branch along with the task key. You can look for the task key to see which code implemented which task.
  • Release branching- as soon as the develop branch gets all the required features to be released, then you can create a clone of that branch to form a release branch. You are not allied to add new features after this point.

What is Git?

  • Git is one of the majorly used Distributed Version Control systems (DVCS). It allows the team to track changes made to a file and then revert to any specific changes.
  • It is usually preferred over other Version Control Systems (VCS) like SVN as Git does not rely on a central server to keep all the versions of a project’s files. Instead, every developer creates “clones” of a repository with “Local repository” and keeps the complete history of the project on the local system that can be referred to when there is a server outage. For complete recovery, you can access your teammate’s local Git repository.
  • It comes with a central cloud repository where developers can commit the required changes and share it with other developers where all collaborators are making changes “Remote repository”.

Containerization-DevOps questions

Explain Docker.

Docker is an open-source project that allows you to create containers and container-based applications. It was designed for Linux systems but now can also be used on Windows and Mac systems. Docker enables you to create independent applications that do not rely on the underlying infrastructure. Docker allows you to manage the infrastructure as you manage your applications. It eliminates the delay between writing code and running it in the production environment.

Explain Docker Architecture.

  • Docker is based on the client-server architecture.
  • Docker Client is a service that will run a command which gets translated using the REST API and then sent to the Docker Daemon (server).
  • Docker Daemon receives the request and communicates with the operating system for building the Docker images and running Docker containers.
  • A Docker image specifies a template holding various instructions for creating containers.
  • Docker container is an executable package that consists of an application along with its dependencies bundled together.
  • Docker registry is a service that will help in hosting and distributing Docker images among users.

Explain the Benefits of Docker.

Below are various benefits of Docker.

  • It provides a consistent and isolated environment for running applications or containerized applications independently without relying on the underlying infrastructure. You can deploy your applications anywhere.
  • It helps in faster deployments as you can run containerized applications independently. As these applications are bundled with their dependencies so they will not take time to look for the dependencies elsewhere.
  • It helps in easy maintenance as each container is isolated from the other, allowing teams to troubleshoot easily with quick fixes.

  • Docker ensures a faster way for deploying applications without focusing on the deployed platform.
  • Docker comes with seamless integration with the DevOps development and deployment cycle.

What are the Key elements of Continuous Testing tools?

Key elements of Continuous Testing are:

  • Risk Assessment: It helps in conducting risk mitigation tasks, technical debt, quality assessment, and test coverage optimization for ensuring that the build is ready to move to the next stage.
  • Policy Analysis: It ensures all processes adhere to the organization’s evolving business and compliance demands.
  • Requirements Traceability: It ensures that all the desired requirements are met without any rework. An object assessment identifies if any requirements are at risk, working as expected or not, or require further validation.
  • Advanced Analysis: It uses automation for static code analysis, changes impact analysis and scope assessment for eliminating defects in the first place
  • Test Optimization: It ensures tests provide accurate results.

Explain the usage of the Docker file.

  • Using Dockerfile, you will be able to create Docker images using the build command.
  • With a Docker image, you will be able to run the code for creating the Docker containers.
  • Once a Docker image is built, it will get uploaded to a Docker registry.
  • From the Docker registry, anybody can download the Docker image and build a new container whenever required.

Difference between Docker image and Docker container.

Docker Images Docker Container
Docker images can be used as a template of Docker containers Containers are considered to be runtime instances of a Docker image
Any user can create an image using a Dockerfile You can create Containers using Docker images
You can find an image in the Docker repository or a Docker hub You can find the container in the Docker daemon
The Docker image layer is a read-only filesystem Every Docker container layer is a read-write filesystem

Creating a Docker Container.

A user can either create a new Docker image or can pull an existing Docker image (like Apache) from Docker Hub (official Docker repository).

Now, you can use Docker for creating a new Container Apache using the existing Docker image. At the same time, the container layer of the read-write filesystem will also get created on top of the image layer. You can run the below-mentioned commands.

  • Command for creating a Docker container: Docker run -t –i Apache
  • The command for listing down all the running containers: Docker ps

Difference between Registry and Repository.

Registry Repository
A Docker registry is available as an open-source server-side service that is usually used for hosting and distributing Docker images. It is a collection of several versions of Docker images
Users will be able to distinguish between Docker images with their tag names that are available in the registry. It is stored in a Docker registry
Docker comes with its default registry known as Docker Hub. There are two types of repositories: public and private

What to Monitor?

To ensure the better performance of the system, you need to monitor various things. But first, you need to be sure what things you need to monitor within your system and to what level to ensure effective functioning of the system. Here, we have mentioned some of the categories that need deep monitoring:

1. Monitoring Server Health

You need to monitor the health of the server to ensure enhanced performance and uptime by optimal consumption of the available resources. The DevOps team needs to configure its resources efficiently to identify the critical endpoints within the application. Also, make sure that the applied configurations are compatible with the system to work seamlessly.

2. Monitoring the Output of an Application

One of the major aspects of DevOps that needs to be monitored is logging the output of an application which is mostly ignored. You must implement a centralized logging system that will help in checking for the potential errors within the system. Make sure that you use the right tools and strategies to throw an alert for occurring certain errors in real-time for preventing the system from vulnerabilities. These logs are used by the IT teams and system administrators to troubleshoot the expected errors and identify the root cause for a quick resolution.

3. Development Milestones

After implementing the DevOps methodology, you need to keep track of how well the DevOps strategy is working and getting better workflow insights. It allows you to monitor how well the different teams are collaborating. You should also keep a check on the sprint durations, error identification rate, resolve rate, and other features for improving the system’s performance. Keeping proper checks in place will help you in achieving the tasks’ deadlines.

4. Monitoring User Activity

Various types of users are using your software and any unusual behavior of the user may hinder your software’s performance. So, you need to check every user’s accounts and make sure they are protected with proper authentication methods and have the right role-based access to different applications. Also, you need to keep an eye on what is being accessed by which user to ensure safety.

How to Choose the Right Monitoring Tools?

There are many monitoring tools available. However, while choosing the right tool, you should select the one that is efficient in gathering the right metrics about the system’s performance and time-series data from multiple sources. Also, the tool should be capable of tracking the applications for various alerts and collecting data in databases.

Various tools come with different sets of functionalities, but only the right one will be able to solve your purpose of implementing a proper monitoring strategy in place. Here, we have mentioned below some of the functionalities that you might consider:

1. Dashboards

The chosen monitoring tool must provide an interactive user dashboard for getting real-time insights into your applications. It should be convenient for every user to use and work on the tool to analyze what is going on within the system.

2. Diagnosis

The tool should be able to look for the critical endpoints for potential vulnerabilities within the system. You will get to know that all your applications are working as expected.

3.  Data collector

You should be provided with an open-source agent that provides the required support for the programming language to collect the data.

4. Data retention

The tool should allow you to collect the real-time time-series performance of the data and log that data.

5. Notifications

The monitoring tools should be well-incorporated with an easy notification system that will throw the right alerts about the tasks and latest updates.

6. Reports

Using the monitoring tool should help you to report all the running tasks, activities, and insights to enhance the performance.

Once you start working on a monitoring strategy using the required tools, you must be able to optimize your strategy efficiently. The monitoring process comes with a standard procedure and will consume time with repeated manual work. It is recommended and preferred that you automate the monitoring tasks for getting regular updates.

You can also set alerts to get desired notifications, generate reports and the required notifications that need to be sent across the system. Automating everything will optimize the monitoring process and reduce the manual work to get insight into the system’s performance and speed.

Set your Monitoring and Alerting Priority

First, check for the critical and most important applications, services, and tasks involved within your system. Once you understand the priority of these applications and tasks, you can fix which task should be run first and what type of notification should be generated in the first place. Suppose you are running small deployments, and at the same time, both your server and code get compromised. What will you do and what will you prioritize first? Thus you set the priority for the alerting system to send you a notification about the critical situation instantly so that the required team identifies the root cause and fix that issue without any system breakdown.

Setting the priority will be beneficial for the IT team as they will be notified about the critical issues soon. This will allow the IT team to respond instantly and provide better customer service.

Monitoring the Application Stack

The monitoring tool should be capable of monitoring the complete stack providing a faster troubleshooting process. The tool must provide the below-mentioned feature set in the application.

1. Infrastructure monitoring

It should focus on the monitoring of the availability of the system’s resources like CPU usage, disk usage, uptime, response time, database, storage capacity, performance, security, network switches, server load, etc.

2. Performance monitoring

It should monitor your SLAs, browser speed, end-user transactions, throughput, error rate, page loads, etc.

3. Network monitoring

It should monitor your network packet flow, bandwidth, latency, network topology, etc.

Conclusion

Automation is one of the salient features of DevOps methodology. It helps in automating various manual tasks that will help in improving the performance and productivity of the team. But this automated pipeline needs to be monitored well to get a better insight into your system. It will keep you updated with the right alert at the right time. Thus, you can use the monitoring tools to manage various tasks simultaneously. You can automate the monitoring tasks to save your time and efforts by checking the system again and again for the same thing. With the right monitoring tool, you will get the complete report so that there is no need to go to every application for health checks.

DevOps Principles

March 18, 2022 admin DevOps

Before the introduction of DevOps, development and operation teams were isolated. The developers’ task was to write code, and the system administrators focused on the deployment of that code. Due to the lack of communication between these two teams, some impact can be seen on the teams’ productivity, and the performance, delivery, and maintenance of the product.

But with the introduction of DevOps, the agile approach has changed in a better way and improved the software development process. Now we must change the approach and team role for releasing frequent releases. Thus DevOps came into the picture to emphasize the collaboration of the two teams. It leads to increased productivity and performance.

In this article, we will highlight what DevOps is and its key principles that create the base for the benefits of DevOps.

What is DevOps?

DevOps is a combination of development and operations. This approach emphasizes the merger of development, operations, and quality assurance into a single process. It is an extension to the agile methodology but with better team collaboration.

If you have implemented the DevOps approach properly within your business, then you will enjoy benefits that cover the technical and cultural aspects of the development.

  • High-quality product releases: DevOps helps in speeding up product release by using continuous delivery, faster feedback, and enabling developers to troubleshoot and fix bugs in the system in the early development stages. Implementing DevOps helps the team to focus on creating a quality product and automate several processes.
  • Improved responsiveness: With DevOps, the specific IT team are capable of making the desired and quick changes as per the changing client’s request such as adding new functionalities and updating existing features. Thus increasing the time-to-market and value-delivery rates for your business.
  • Better working environment: the main purpose of using the DevOps approach is for improving the team’s internal communication that will help in bridging the gap between team members and increasing productivity and agility. Teams that work on the DevOps approach tend to work more effectively and productively. This leads the teams to work together on the same problem resulting in quick problem resolution.

To leverage these benefits of DevOps, you have to implement it with the right strategy. DevOps is not a set of instructions but a philosophy that emphasizes cross-functional team communication. It mainly focuses on improving the way people work within organizations. The success and productivity of any organization will eventually depend on how they stick to the DevOps principles. For better understanding, we will be focusing on various DevOps principles that have to be employed.

DevOps Principles

1. Foster a Collaborative Environment

Earlier in the agile methodology, the main focus was on releasing small sprints and getting customer’s feedback for quick changes at the early stages. This feature has been extended within the DevOps approach that majorly emphasizes on team collaboration. This will eventually improve the productivity and performance of the team. Various teams come together to code, deploy, and test the product. This leaves a very small chance of errors in the delivered product. Working together will save the time consumed in the development.

If development and operation teams work together, they can work on updates and fixes efficiently and deliver the new product within time. This timely delivery of a product is good for both parties. This team collaboration even helps them to brainstorm and share various ideas for better development.

2. Combine the Incentives for Developers and Operations

To avoid conflict between the development and operation teams, the company should set a similar objective for both teams. Generally, the development team is assessed based on the speed to add new features to the product and the operational team is assessed based on managing the uptime during deployment. Both the performance metrics are different from each other but together they create the impression of any business.

When the goals for both the teams become common then the role will get shifted from “I write the code” to “I am responsible for the end product”. These cultural changes have improved the working environment for both teams by eliminating the inefficiencies in their performance.

Organizations must employ multi-skilled people who can focus on every development pipeline task and deal with all types of bottlenecks at the early development stage.

3. Minimizing Failure Cost

The main difference between the continuous delivery and the traditional release culture is how they manage and react towards failure. They do not consider the failure as a part of the SDLC process which is important to work towards improvement. But with the introduction of DevOps, teams started focusing on failures and tried to eliminate the fear of failures as they built a product in chunks. The main focus is to lower the cost due to failure by improving the way of working.

DevOps allows the team to break the deliveries into small parts, resulting in better management of each part and fostering productive cross-platform collaborations. If you notice, managing your product in small chunks will cost less. This strategy will help the developers to treat such failures as milestones in the process of software development. This leads to the creation of a performance-driven environment rather than blaming someone for those failures. In the end, the business will see the difference in the performance and productivity of the teams.

4. Automate All Possible Tasks

With DevOps, every task is processed in continuation and leaves no time to waste. For frequent product deliveries, you must minimize the manual work and automate most of the software development aspects. Well, there is no limit and restriction on how much automation you can imply to your SDLC pipeline. With proper automation, you can enable a lightning-fast user feedback loop. Sometimes focusing on high speed may become the reason for human-led errors. Thus you can automate the tasks to avoid errors and rework them to save the team’s time and efforts.

Automating tasks will not require manual interventions and are more effective than doing the task manually every time. You will be able to automate the various processes in the continuous integration and continuous delivery pipeline like provisioning of infrastructure, creating new systems, deployment of software, and testing.

5. Improve Continuously

With DevOps, you will be able to improve continuously without any doubt. By eliminating the fear of failure, automation, and equal responsibilities of teams, DevOps has done a lot by contributing to the improvement of the entire working process. It allows you to manage and fine-tune the smallest detail of the system. Effective team collaboration will help in improving the product quality to some extent and make it easier to add new functionalities to the existing software without any hassle.

Conclusion

The simple approach and effective principles of DevOps have benefited many organizations. It helps in speeding up the development process to create and deliver high-quality software. Surely, the life of DevOps is not going to end soon. If you have implemented and followed the DevOps principle efficiently then you can leverage the true benefits of DevOps. Not only this, DevOps works well with cloud platforms making it the next big technology in the market.

To lead your company in the right direction of improvement, you can focus on various DevOps principles by implementing them well.

Agile vs DevOps

March 18, 2022 admin DevOps, Difference

Today, the field of software development is evolving, and you can discover a variety of apps in the market. There are two different methodologies for software development – Agile and DevOps. They both aim to create an end product efficiently and quickly as well as one of high quality. Both methods are very popular and many companies are interested in integrating them into their working processes. However, there is some confusion when we are discussing which software development methodology to employ. To choose the right one for your business type, you need to know what each covers, what their similarities are, whether or not they can be combined, or how they differ.

In this article, we will learn how Agile and DevOps have been used, how they differ from each other, where they overlap, and how they can be implemented together if required.

What is Agile Methodology?

Agile method allows you to manage projects and develop software using an iterative approach that places an emphasis on collaboration, customer feedback, and rapid but stable releases. The method was introduced in the early 20s to help various industries to develop software and teams to adapt to the changing market.

Using the Agile methodology, some of the planning is done upfront but the development is done in small fragments along with the close collaboration with the clients to understand their changing needs and to incorporate time to time feedback of that development. Having the option to make a change instantly means that huge changes won’t need to be made at a later stage of development. When using the Agile method, one of the major benefits is that you can make changes in real-time based on changing demand.

You can’t consider Agile as a single method for developing software. It is a collection of methods. It is a combination of various practices that have been combined to make the development process quicker and more efficient.

What is DevOps Methodology?

Like Agile, DevOps is also an approach for developing software that allows the team to build, test, and deploy the software in a faster and more reliable manner. It somehow incorporates agile technology, rules, and principles like automation, enhanced collaboration among various working teams. But in comparison to the traditional method of agile, DevOps is highly preferred because of its modern way of developing software.

With DevOps, you are able to bridge the gap between the operational team and the development team so they can collaborate in an efficient manner for creating a better quality product. Not only this, it allows the teams to build and maintain the infrastructure. DevOps helps in increasing the visibility and helps the operational and development to work together so they can handle the complete process efficiently and seamlessly. It encourages both teams to work together from the very beginning to ensure that they are on the same page.

Similarities between Agile and DevOps

Below are some similarities of Agile and DevOps methodology.

  • Both are used for the development of software.
  • Both work for the fast delivery of products with high quality.
  • Both encourage team collaboration.

Agile vs DevOps: Contrasting points

Following their similarity, we have described some differences between them. You will understand which methodology to choose once you understand their differences.

  • Speed- if we look at Agile’s speed of development, then it’s concerned primarily with delivering the product in a faster manner and considers it a major goal. However, this is hardly the case with DevOps, as it does not emphasize speedy development.
  • Specialization- agile provides its team members with equal opportunities. All scrum members can perform all tasks that stop the process from slowing down. DevOps teams are separated into operational and development teams, but they communicate often to maintain alignment.
  • Communication- Agile process includes frequent meetings where they can share the daily progress, goals, and indicate whenever they need help from others. You can use scrums for discussing the progress report but not the metrics or milestones. For that they need to conduct another meeting. While in DevOps there are no such frequent meetings.
  • Documentation- agile teams do not maintain notes of their meetings or communications in detail. They just note down the important points like the required changes and others. While DevOps majorly focus on the documentation and create a detailed document for understanding the software release completely.
  • Team size- agile maintains small team size so they can move and respond faster whether it takes a lot of effort from every team member. While in DevOps, they have various teams working together for specific work so they can focus on a specific task to improve the performance and productivity of the team and project.
  • Agile teams have a set amount of time known as sprints that will last for a short period of time, like a month or a week. As DevOps, however, focuses on long-term schedules that improve business processes, you gain the greatest reliability.
  • Automation- DevOps is based completely on automation as its overall aim is to minimize disruptions and improve the system’s efficiency. While agile does not require automation.

Head to head comparison of Agile and DevOps

Grounds Agile DevOps
Basic Philosophy It majorly aims at continuously delivering the small and manageable increments of a project using iterative development and testing process. Encourages development and operations teams to work together to enhance productivity.
Use You can implement it in any department for managing a complex project. Majorly aims at the end-to-end development process.
Focus Allows and encourages the mid-project changes for improving quality. Combining the development and operations teams for ensuring continual testing and development.
Team Working as a small group of people with similar skills. Large team with various skillsets
Delivery Incremental and continuous deployments after each sprint Aims at providing continuous delivery daily
Documentation Comes with light documentation for enhancing flexibility in the development process. Sufficient documentation ensures team collaboration.
Quality and Risk Ensuring the release of the quality product as the changes are being done after every sprint minimizing the risks. Focuses on creating high-quality products with low risk based on effective collaboration and automated testing.
Feedback Aims at customer feedback and makes changes to the product accordingly. Focuses on the internal team feedback for better performance.

DevOps and Agile Can Work Together

Agile and DevOps both focus on delivering quality software frequently and rapidly. It is important to emphasize that one of the major differences between Agile and DevOps is that Agile helps in optimizing the software development life-cycle, while DevOps aims at integrating both development and operations teams through continuous integration and continuous delivery.

DevOps and agile are not mutually exclusive. If any organization is moving towards the DevOps methodology then it should not leave the existing Agile workflows aside. DevOps is considered to be an extension of agile methodology that is built on the top of the agile practices and methods that are not in agile’s focus. When we use both methodologies together, they will work together to improve the software development and lead to the development of better products.

Conclusion

There are benefits and principles to both Agile and DevOps for software development. Creating software with a high level of quality and in a productive environment is the major focus of both. When implemented properly, both methodologies are effective. DevOps is a complement to your agile methods in that it imposes some rules and methods on us that Agile doesn’t provide. As a result, upgrading your methods for better software development does not harm you. DevOps can even be integrated with cloud technology for faster and more reliable software development.

What is Puppet in DevOps?

November 1, 2021 admin DevOps

If you have come across a system administrator, you will know that they always complain that most of their time is wasted in checking the configuration of the servers. If any setting changes and the developers or programmers face any issue, it halts the work and slows down the entire process.

You must have heard about Puppet recently. With Puppet, DevOps found a way to automate system configuration. As you learn more about it, you will understand how perfectly it fulfills its function.

In the competitive environment, the success of an organization depends on how fast it can deliver value to its customers. Puppet plays a major role in this process as it automates time-consuming processes and functions.

In this guide, you will learn everything about Puppet, i.e., what is Puppet, what it does, how it is useful, etc.

What Is the Puppet?

Once upon a time, i.e., a few years back, the system administrators managed system configurations manually. System administrators could perform configuration settings manually if the operations were small and there were few servers. However, for large organizations, it was a lot more work. There was therefore a strong need to automate this process.

Then came Puppet, a configuration management tool that has made DevOps more than happy. Configuration management includes the management of the physical and functional attributes, the operational information, the design, and the requirements of a product throughout its life cycle. An administration team can save thousands of working hours by using this system management and deployment tool. With this tool, configuration tasks can be carried out simultaneously across multiple servers.

Say you have 1000 application servers. Imagine the time it will require to make configuration settings, maintaining, and managing these servers. Puppet undertakes this responsibility and configures the servers to predefined configurations set by the user. It controls the infrastructure, and configurations and policies are defined in codes. Thus it uses Infrastructure as a code that is carried out on each server.

Puppet is free, as it is open-source, but, of course, a commercial version is also available.

Brief History of Puppet

Puppet Inc owns Puppet. Like Kanies designed it in 2005. Earlier it was built as cross-platform software. The Puppet Enterprise was the primary product designed by Kanies to assist the DevOps team during the entire SDLC. Both Linux and Windows servers use Puppet today.

Do you know, almost 42 percent of all the organizations that use DevOps use Puppet? Even companies like Microsoft and IBM are Puppet users.

How does Puppet Work?

You must be wondering now that you know it’s a configuration management tool, but how does it work? The answer is here.

Puppet is written in a declarative Domain-specific language which is like Ruby. This language is used to write codes depending on the environment. It manages configurations separately for Unix and Windows environments.

The entire operation is carried out by the Puppet Master system, which collects the information about systems using a utility called Factor and stores it in Puppet manifest. You must know that Puppet capitalizes on client-server architecture very efficiently.  

The nodes that run the Puppet Software are termed Puppet Agent. These agents have the most privileges to change the system settings to apply the configuration changes. These agents work for the master and send all the information to Master, who then decides how to configure each server. The predefined configuration settings are then dictated to the Puppet Agents, who then configure themselves.  

Puppet master runs on a dedicated system. It is a daemon, and it is the master that runs the whole show of configuration as a background process. The Puppet Master is the Server for all the clients that runs Puppet Software as a background process and sends queries to and receives answers from Puppet Master. This is Puppet Architecture.

In simple words, all the servers are connected to a server or Puppet master via software. Then they upload the data about themselves, i.e., Puppet Agents, and the system tells them what configuration is ideal for them. These servers then install the pre-defined configuration on themselves.

In this way, the entire operation is carried out flawlessly by computers themselves. The process is overlooked by Puppet, which works on the master itself and performs various functions that include ensuring that the operation is not compromised. To ensure this, the master and agent use an SSL certificate and TLC protocol. It allows the master and agent to authenticate to each other and restrict interference or eavesdropping.

Why use the Puppet?

As it was said earlier, Puppet uses a code to configure servers. Most organizations use it as it is easy to write usable codes, even the complex ones, using different profiles and roles. The Puppet codes are divided into three roles-

  • Component modules- This is the most basic level which deals with only one particular technology.
  • Profiles- When you are writing code for a layered technology configuration, this class is called a profile composed of multiple component modules.
  • Roles- This class is made up of multiple profiles, which is used for more complex configurations.

It may look complex but it is cakewalk, and it is easier to make changes later on.

Benefits of Using Puppet

There are several benefits that organizations derive from using Puppet.

Reduces Configuration Time

As the entire process is automated and numerous servers are configured simultaneously, it decreases the configuration time to a great extent.

Expanded Reach

Manually, it is quite difficult to maintain and manage the configuration of thousands of servers. But with Puppet, you can reach numerous servers in a short time. It is a boon for large organizations.

Reduced Cost

Puppet is available in both free and commercial versions. Using a free version, the organization can automate its configuration at zero cot.

Simplicity

Puppet uses a hierarchical design of writing codes which is quite simpler than other complex applications.

Continuous Deployment

Puppet manages the system through the entire software development life cycle by automating the operations and using its continuous deployment tools.  

Conclusion

In a world where even the smallest of the operations are being automated, DevOps are not supposed to stick with old ways of operations. Every day new software applications are launched. Customers expect a shorter delivery time. They are the king. It becomes an organization’s responsibility to fulfill customer expectations.

Puppet plays a major role in it as it works on a continuous delivery model, assisting the DevOps teams to reduce cycle time and work simultaneously without waiting for handoffs and waiting for the configurations to complete.

In this guide, you’ve learned about what Puppet is, how it came into existence, what it does, how it works, why companies use it, etc. You learned how automation can save hundreds of working hours that were earlier wasted on redundant manual work. This is a beneficial tool. Try it within your organization, and you will learn more about its benefits.

10 Best DevOps Tools You Should Use in 2021

March 4, 2021 admin DevOps

Almost every IT company has included the DevOps process within their system. It is an approach that will manage the CI/CD process more comfortably and efficiently. It has created a platform where both IT operations and the development team can work together as a team throughout the complete software development cycle from the development to the deployment phase. Before the DevOps process, these two teams worked as different entities handling the various tasks and somehow led to increased development time, low throughput, etc.

DevOps has changed every organization’s work by increasing production time, reducing cost, and fewer failures. There is no doubt how the DevOps approach can be easily fit to any organization. In this article, we have mentioned DevOps, its benefits, its challenges, and various DevOps tools.

What is DevOps?

DevOps is an approach that allows the merger of the traditional software engineering process and improves the communication to enhance the frequency of production releases while maintaining the software quality consistently. It is claimed that many organizations have experienced its benefits, but there are very few practical examples. But with DevOps, any business tends to increase the release frequency and improves the test automation practices.

Not only this, DevOps encourages team collaboration on a large scale across various departments to boost employee welfare. If you implement continuous release practice, it will lead to rapid feedback from the end-users to improve the product. It may be possible that DevOps works differently for various organizations and does not fulfill their expected results. Before implementing the DevOps approach, you need to understand what practices they need to implement for DevOps.

Benefits of Using DevOps

Implementing DevOps approach will benefit your organization in the following ways:

  • Implementing DevOps makes sure your releases are done faster, you will efficiently adapt to the changing market needs, and you will produce better results than expected.
