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.
  • With DevOps, the releases are done faster, which improves the product quality by providing you consistent feedback.
  • DevOps has improved the CI/CD process by ensuring the application updates quality and changes in the infrastructure, improving the experience for the end-users.
  • It has improved the way of collaborating within the teams to ensure higher productivity. In this manner, all the team members will be on the same page while developing and deploying the product in production.
  • You can implement various security tools to secure the complete process.
  • DevOps applications are scalable and easy to maintain as it uses the cloud technology and the microservices architecture.

Challenges of Using DevOps

Below are the various challenges you may face using DevOps:

  • Challenges during the transition- if you are currently working with the legacy systems and want to rebuild your applications for microservices architecture or move them on the cloud, it may not be possible by adopting the DevOps approach.
  • Inadequate talent- it is challenging to find the perfect and skilled DevOps team with hands-on experience. Today, DevOps engineers are in great demand and have an excellent pay scale. But there are not enough qualified employees for the job.
  • Choice of toolset- today, there are various tools available for the DevOps approach, making it easier to switch to this technology.

You may change to different tools later, but moving all the applications to another tool can be difficult and a waste of time.
