Week 12 Achievements:

  • CI/CD Pipeline:

    • Configured AWS CodePipeline for automated deployment
    • Connected pipeline to Git repository
    • Set up build stage with CodeBuild
    • Automated backend deployment to EC2
    • Automated frontend deployment to S3 with CloudFront invalidation
    • Tested complete CI/CD flow: Git push → Build → Deploy
  • Monitoring & Logging:

    • Configured CloudWatch Logs for Spring Boot application
    • Set up CloudWatch metrics for EC2 and RDS
    • Created CloudWatch alarms for high CPU and memory usage
    • Enabled API Gateway access logs
    • Implemented application-level logging with proper log levels
  • Testing & Quality:

    • Wrote unit tests for backend services (JUnit)
    • Created integration tests for API endpoints
    • Performed manual E2E testing for all user flows
    • Fixed bugs discovered during testing
    • Optimized database queries for better performance
  • Documentation:

    • Created comprehensive README with setup instructions
    • Documented all API endpoints with request/response examples
    • Wrote deployment guide for team members
    • Prepared project presentation slides
    • Documented architecture decisions and trade-offs

Challenges Encountered:

  • CodePipeline Configuration: Build failures → Fixed Maven dependencies and build script
  • CloudWatch Logs: Logs not appearing → Configured IAM role for EC2 CloudWatch access
  • Performance Issues: Slow API responses → Added database indexes and query optimization

Key Learnings:

  • Mastered AWS CI/CD pipeline setup
  • Understood importance of monitoring and logging in production
  • Learned testing strategies for full-stack applications
  • Improved documentation and communication skills

Project Summary:

  • Frontend: React + Vite deployed on S3/CloudFront
  • Backend: Spring Boot deployed on EC2
  • Database: MySQL on RDS
  • CI/CD: Automated pipeline with CodePipeline
  • Monitoring: CloudWatch logs and metrics
  • Security: JWT authentication, HTTPS, Security Groups
