CodePipeline CICD Workflow

Key Components and Responsibilities

1. Source Control (GitHub)
   • Stores application source code.
   • Triggers pipeline execution on new commits to the repository.
2. GitHub Actions (CI - Continuous Integration)
   • Runs unit tests and builds artifacts before AWS deployment.
   • Prevents broken builds from entering AWS CodePipeline.
3. AWS CodePipeline (Orchestration Service for CI/CD)
   • Manages the deployment workflow.
   • Triggers AWS CodeBuild for application testing and packaging.
   • Deploys the application based on the configured target (Lambda, Elastic Beanstalk, or EC2).
4. AWS CodeBuild (Build and Test Service)
   • Installs dependencies, runs tests, and packages the application.
   • Generates deployable artifacts.
5. Deployment Targets (Choose one or multiple based on application needs)
   • AWS Lambda: If the application is serverless. -< Using Lambda
   • Elastic Beanstalk: If using managed infrastructure for web apps.
   • Amazon EC2: If requiring full control over servers.
6. AWS CloudWatch (Monitoring & Logging)
   • Logs build and deployment activities.
   • Provides real-time pipeline insights.
7. Rollback Mechanism (For Failures)
   • Ensures automatic rollback if deployment fails.
