Introduction to DevOps

DevOps Loop

Stage	Description
Plan	Define project scope, objectives, and requirements. Collaborate on project planning.
Code	Develop and commit code changes to version control. Emphasize code quality and collaboration.
Build	Automate code compilation, artifact creation, and packaging.
Test	Execute automated tests, including unit, integration, and end-to-end tests.
Release	Deploy applications to staging environments for testing and validation.
Deploy	Deploy applications to production environments. May include manual approval gates.

Cont.

Stage	Description
Operate	Manage and monitor the production environment. Utilize monitoring and alerting tools.
Monitor	Continuously monitor application and infrastructure performance. Collect metrics and logs.
Feedback	Analyze data, post-incident reviews, and gather feedback to identify areas for improvement.
Iterate	Continuously improve processes and applications based on feedback and insights.
