Introduction

DevOps Lifecycle is a methodology which software development teams use to bring products to market more quickly and efficiently. It’s a way of managing the entire software lifecycle from development through release, focusing on collaboration between developers and IT operations professionals. Constant software creation, development, verification, release, and management are part of the DevOps lifecycle.  

The following are the steps at how the DevOps lifecycle functions at each phase:

• Plan – Professionals determine the commercial need and gather end-user opinions throughout this level. In this step, they design a project plan to optimize business impact and produce the intended results.
• Code – During this point, the code is being developed. To simplify the design process, the developer team employs lifecycle DevOps tools and extensions like Git that assist them in preventing safety problems and bad coding standards.
• Build – After programmers have completed their tasks, they use tools such as Maven and Gradle to submit the code to the common code source. 
• Test – To assure software integrity, the product is first delivered to the test platform to execute various sorts of screening such as user acceptability testing, safety testing, integration checking, speed testing, and so on, utilizing tools such as JUnit, Selenium, etc. 
• Release – At this point, the build is prepared to be deployed in the operational environment. The DevOps department prepares updates or sends several versions to production when the build satisfies all checks based on the organizational demands.
• Deploy – At this point, Infrastructure-as-Code assists in creating the operational infrastructure and subsequently publishes the build using various DevOps lifecycle tools.
• Operate – This version is now convenient for users to utilize. With tools including Chef, the management department take care of server configuration and deployment at this point. 
• Monitor – The DevOps workflow is observed at this level depending on data gathered from consumer behavior, application efficiency, and other sources. The ability to observe the complete surroundings aids teams in identifying bottlenecks affecting the production and operations teams’ performance. 

Conclusion

The Software Development Life Cycle (SDLC) is a systematic and structured approach to software development that uses various phases and activities to ensure the successful creation and maintenance of software applications.
