Week 12 Achievements: System Finalization & Handover Readiness

1. Performance Evaluation & Tuning

  • Monitoring:
    • Established a CloudWatch Dashboard to visually display key metrics: CPU Utilization, Request Count, Database Connections, Error Rate (4xx, 5xx).
    • Configured SNS Alerts to send email notifications to Admins when system issues occur.

2. Optimization & Advanced Security

  • Security:
    • Enabled WAF (Web Application Firewall) to block common attacks (SQL Injection, XSS).
    • Reviewed IAM Roles and revoked unnecessary privileges.
  • Cost: Based on data from the 2-week pilot run, resized Instances from t3.medium to t3.micro for the Dev environment to save costs without impacting performance.

3. Project Completion

  • Documentation: Completed the project documentation suite including: Updated Architecture Diagram, Redeployment Guide, and Cost Report.
  • Lessons Learned: Gained insights into handling “Cold Start” issues during Auto Scaling and the importance of accurate Health Check configuration.
