3Continuous Improvement for Existing Solutions

• 3.1Operational Observability and Automation

  Understand observability and operations for improving existing systems—CloudWatch (metrics/logs/alarms), X-Ray (distributed tracing), CloudTrail (API auditing), Systems Manager, and automation. Detect issues early and automate operations.

• 3.2Performance and Cost Optimization

  Understand optimizing existing workloads—right-sizing, purchase options (On-Demand/RI/Savings Plans/Spot), Compute Optimizer/Cost Explorer/Budgets/Trusted Advisor, and CloudFront/caching. Keep performance while cutting waste.

• 3.3Improving Reliability and Security Posture

  Understand hardening existing systems—Well-Architected, fault isolation, GuardDuty/Security Hub/Config, WAF/Shield, and automated remediation. Continuously raise threat detection and compliance.

• 3.4Developer Tools and Operations Management Services

  Supporting services for improvement and automated delivery—CI/CD pipelines (CodePipeline, CodeBuild, CodeDeploy, CodeArtifact, CodeGuru), open-source-compatible observability (Managed Grafana, Managed Service for Prometheus), standardized templates (Proton), and frontend/testing (Amplify, Device Farm)—by definition, role, and when to choose.
