We've reached the end! Recap from Day 14 and the series.
Best Practices
- Use Fargate for simplicity.
- Implement least privilege IAM.
- Enable logging/monitoring.
- Use blue/green deployments (new in 2025 for safer releases).
- Cost: Monitor with Cost Explorer; use Spot for non-prod.
| Category | Tip |
|---|---|
| Security | Scan images, use private ECR. |
| Performance | Right-size CPU/memory. |
| Cost | Auto-scale, delete unused. |
Troubleshooting
- Permissions: Check IAM errors.
- Networking: Verify SGs, subnets.
- Logs: Use CloudWatch for container crashes.
- Common: "No Container Instances" – add capacity.
Next Steps
- Explore ECS Anywhere for on-prem.
- Try Kubernetes with EKS.
- Build a full app: Add DB with RDS.
Cheat Sheet:
- Cluster:
aws ecs create-cluster - Task:
