What is DevOps lifecycle?

It is a process where the development and operations team work coordinately right from the initiation of the specific product development till the last phase of its completion. 

There are seven phases in the DevOps lifecycle, which are as follows:

1. Continuous development: Application objectives must be planned properly in accordance with the customer requirements. Developers initiate the process by developing the code for the specific application. For maintaining the code, there are specific tools available. By using any programming language, the code can be written and it is maintained using version control tools.

2. Continuous integration: In this phase, developers must take the responsibility to commit changes to the source code regularly. It can be carried out on a daily or a weekly basis. Then every commit is built, which allows early detection of issues if there are any.

3. Continuous testing: The developed software is tested continuously for bugs. Automation testing tools such as TestNG, JUnit, Selenium can be used for carrying out testing activities. Multiple codebases can be thoroughly tested in parallel using these tools, which in turn ensures that there are no errors in the functionality.

4. Continuous monitoring: The performance of the application is continuously monitored in this phase. Important information about the software usage is recorded. In order to recognize the application’s proper functionality, this particular information is processed.

5. Continuous feedback: The results are analyzed by observing the performance of the software application and making improved changes if need be required. Constant feedback is taken from the development and operations team so that the current and next versions of the software application can be more refined.

6. Continuous deployment: In this phase, the specific code is being deployed to the production servers. Code should be correctly deployed across all the servers. Some of the popular tools that are used in this phase are Ansible, SaltStack, Chef, and Puppet.

7. Continuous operations: Consistency is the key to carry out the DevOps operations smoothly, and also the delivery procedure is entirely computerized.
