DevOps lifecycle forms an agile connection between the development teams and the operations teams. It is a streamlined process where different phases are being involved and plays an integral role in the DevOps lifecycle.
Following are the six different phases of the DevOps Lifecycle:
1. Continuous development: The planning and coding of the software are involved in this phase. In the planning phase, the project’s vision is decided. Then the developers will initiate the work of developing the code for the application. The code can be written in any programming language, but, version control tools are used to maintain it. The code that is being maintained is referred to as source code management.
2. Continuous integration: It is a software development practice in which developers should work upon submitting changes to the code frequently. It can be done on a daily or a weekly basis. A commit is then built, which in turn allows problems to get detected early, if there are any issues as such. Developing code is not limited to compilation, but, also includes integration testing, unit testing, code review and packaging.
3. Continuous testing: In here, the developed software is tested continuously in order to find bugs. For performing continuous testing, tools such as TestNG, JUnit, selenium etc., are used. Multiple code bases can be tested in parallel through these tools by QAs, to ensure that the functionality doesn’t have any flaws. In this phase, for simulating the test environment, Docker containers can be used.
4. Continuous monitoring: All the operational aspects of the entire DevOps process is involved in this phase. Significant information about the software’s usage is recorded and processed carefully to find out trends and identify specific problem areas. Monitoring is included within the operational competencies of the software application.
The real cause of the issue is identified in this phase. The availability and security of the services are maintained. Even network related issues are also resolved in this phase. In most of the scenarios, as soon as the problems are detected, they are automatically fixed.
5. Continuous feedback: By analysing the results of the software’s performance, the application is consistently developed and the quality is improved. Constant feedback is obtained from the development and operations teams to understand the performance and functionality of the current software application that is being developed. Feedback ensures that the current software product is being built as per the customer’s precise requirements so that new versions can be quickly released.
6. Continuous deployment: In this phase, the code is being deployed to the production servers. It is also necessary to note that the code is being used rightly on all the servers. Configuration management tools play a key role in executing tasks quickly and frequently. Some of the popular tools that are being used are Ansible, Puppet, SaltStack, Chef etc.
