Key Concepts

CI/CD Pipeline Stages

1. Source - Code repository integration
2. Build - Compilation and packaging
3. Test - Automated testing execution
4. Deploy - Application deployment
5. Monitor - Post-deployment monitoring

Deployment Strategies

• Blue/Green - Zero-downtime deployments
• Rolling - Gradual instance replacement
• Canary - Gradual traffic shifting
• Immutable - Complete infrastructure replacement

Testing Strategies

• Unit Testing - Individual component testing
• Integration Testing - Component interaction testing
• End-to-End Testing - Full application workflow testing
• Security Testing - Vulnerability and compliance scanning
• Performance Testing - Load and stress testing

Integration Patterns

Multi-Service Pipeline

CodeCommit → CodeBuild → CodeDeploy → CloudWatch
     ↓           ↓           ↓           ↓
EventBridge → Lambda → SNS → Step Functions

Cross-Account Deployment

• Cross-account IAM roles
• Artifact sharing strategies
• Environment isolation
• Security boundaries

Third-Party Integration

• GitHub integration via CodeStar connections (live service; not the retired CodeStar)
• Jenkins pipeline integration
• External testing tools
• Monitoring and alerting systems

Common Exam Scenarios

1. Multi-stage CI/CD pipeline - CodePipeline + CodeBuild + CodeDeploy
2. Cross-account deployment - IAM roles and artifact sharing
3. Automated testing integration - Test stages in pipelines
4. Blue/green deployment - Zero-downtime deployment strategy
5. Container deployment pipeline - ECR + ECS/EKS deployment
6. Infrastructure as Code pipeline - CloudFormation/CDK deployment
7. Security scanning integration - SAST/DAST in pipelines
8. Multi-environment promotion - Dev → Test → Prod pipeline
9. Rollback and recovery - Automated rollback mechanisms
10. Pipeline monitoring and alerting - CloudWatch integration
