DevOps

DevOps is a culture of work and team collaboration aimed at improving cooperation between development and operations.

Phases:

  1. Plan - defining tasks, strategies, and project goals
  2. Code - writing the code defined during planning
  3. Build - integrating the written code into the project (using Git)
  4. Test - testing the project's functionality with the newly added code
  5. Release - final verification, bringing the project to release readiness according to the input requirements
  6. Deploy - deploying the project (using automation tools for maximum efficiency), with various DevOps tools
  7. Operate - working with the deployed project in a real production environment with end users involved.
  8. Monitor - collecting statistical data, feedback, and product usage experience to identify problems and improvement opportunities. After this, the cycle returns to the planning phase.

7C - organizes the phases listed above into a more comprehensible framework:

1) Continuous Development = Plan + Code 2) Continuous Integration = the goal is to remove manual verification, enable automated testing, and deploy the project to a central hub to build it automatically (e.g., using Jenkins) and notify team members about changes. Unit and integration tests, as well as code reviews, are performed here. 3) Continuous Testing = implementing testing, running tests with tools like Selenium. QA engineers work here, determining whether the project meets the customer's requirements and identifying bugs. Test reports are generated. 4) Continuous Deployment = Deploy + Operate. Containerization and tools like Ansible are used. 5) Continuous Feedback - ensuring feedback loops, collecting input from all stakeholders, identifying areas for future improvement. 6) Continuous Monitoring 7) Continuous Operations
