DevOps is a software development Phrase and requirement for development and IT operations. For a development of two business unit’s communication and collaboration elements in the operation. To expedite and actualize DevOps process apart from culturally accepting it, one also needs various DevOps tools like GIT, Puppet, Chef, Docker, Selenium, Jenkins, AWS etc. To achieve automation Continuous Integration, Continuous Development, Continuous Monitoring, Continuous Testing, Continuous Deployment to deliver a quality software to the customer.
Recently, DevOps movement for considering the off-limits to the enterprise, naysayers struggling for large complex and organizations to emulate the agile software development. waterfall-style software development techniques for DevOps to challenge the status. Big organizations are just too weighed down by bureaucracy, legacy. DevOps are fuelling for change within enterprises, as many come to realize that doing things the way they always have done.

For continuous delivery means software projects may not be finished, in the traditional sense, by the time of release and subject to ongoing, iterative improvements.
Many senior leaders are still wedded to the idea of using software maturity models and, in turn, how they should be financed.“The challenge with maturity models, ones that are codified, set in stone in ways that are difficult to break because suddenly you have a target and once you reach that level.
Let us see the life cycle of DevOps and its software stages.
In DevOps lifecycle, the Software is development is continuous. This stage involves the Coding and Building phases, unlike the Waterfall model the software deliverables are broken down into multiple sprints of short development cycles, developed and delivered. And makes use of tools such as Git and SVN for maintaining the different versions of the code, Ant, Maven, Gradle, code into an executable file.
the software is continuously tested for bugs. In this phase use of Docker containers for simulating testing environment on the fly, is also a preferred choice. Once the code is tested, it is continuously integrated with the existing code. For Continuous testing automation tools like Selenium, JUnit is used. These tools enable the QA’s for testing multiple code-bases thoroughly in parallel to ensure that there are no flaws in the functionality.
In this stage, the code supports new functionality integrated with existing code. For integration process a continuous development of software and updated code.
The code is deployed to the production environment. We ensure that the code is correctly deployed on all the servers. A new feature is introduced then one should be ready to welcome greater website traffic. Automation tools play an important role in executing tasks quickly and frequently.The new code is deployed on a continuous basis, SaltStack, Chef, Puppet, and Ansible are tools that are used in this stage.
This is a very crucial stage .which is aimed at improving the quality of the software by monitoring its performance. The participation of the Operations team who will monitor the user activity for bugs and behavior of the system. This can also be achieved by dedicated monitoring tools which will continuously monitor the application performance and highlight issues. Some popular tools used are Nagios, NewRelic, and Sensu. These tools help you monitor the application and the servers.They can also improve productivity and increase the reliability of the systems. Issues would be reported to the Development team.
