- VPC
- S3
- CloudWatch
C. Practical Section
Hands-on commands and examples for real usage.

D. Real DevOps Context
- Used in production delivery pipelines and cloud operations.
- Common platforms: Amazon Web Services, Docker, Kubernetes.
- Common mistake: jumping to advanced tools before concept clarity.
- Industry use: teams use this to improve release speed and reliability.
E. Troubleshooting
CrashLoopBackOff
Why it happens: Container startup failed due to missing env/config dependency.
How to fix: kubectl get pods | kubectl describe pod <pod> | kubectl logs <pod> --previous
502 Bad Gateway
Why it happens: Upstream app process not listening on expected port.
How to fix: sudo nginx -t | ss -lntp | curl -I http://localhost:<port>
High CPU
Why it happens: Hot endpoint and insufficient resource limits.
How to fix: top | ps aux --sort=-%cpu | head | kubectl top pod
F. Mini Practice Task
Try this now: Launch a small EC2 instance and connect with SSH using a key pair.
