      • Application Performance Management
  3. Continuous Integration (CI)

    • Definition and benefits of CI.
    • The process of setting up CI in a development workflow.
    • Importance of automated testing and feedback loops.
  4. Testing Methodologies

    • Test-Driven Development (TDD) and its significance.
    • Types of tests: unit tests, integration tests, end-to-end tests, and acceptance tests.
  5. Deployment Strategies

    • Overview of various deployment strategies:
      • Rolling Deployments
      • Blue-Green Deployments
      • Canary Deployments
    • Importance of zero downtime during deployments.
  6. Application Performance Management

    • Importance of monitoring application performance.
    • Log aggregation and metric aggregation as key components.
    • Tools for log and metric aggregation (e.g., ELK stack, Prometheus).
  7. Service Discovery and Reverse Proxies

    • The role of service discovery in microservices architecture.
    • Use of reverse proxies for routing requests and managing deployments.
