Plan – Initially, there should be a plan for the type of application that needs to be developed. Getting a rough picture of the development process is always a good idea.
Code – The application is coded as per the end-user requirements.Â
Build – Build the application by integrating various codes formed in the previous steps.
Test – This is the most crucial step of the application development. Test the application and rebuild, if necessary.
Integrate -Â Multiple codes from different programmers are integrated into one.
Deploy – Code is deployed into a cloud environment for further usage. It is ensured that any new changes do not affect the functioning of a high traffic website.
Operate – Operations are performed on the code if required.
Monitor – Application performance is monitored. Changes are made to meet the end-user requirements.
The above figure indicates the DevOps lifecycle.
