Troubleshooting

Common Failures

Symptom	Root Cause	Solution
Access Denied	IAM policy	Check policies
Quota Exceeded	Service limit	Request increase
Timeout	Network/SG	Check VPC, SGs
Cost spike	Runaway resources	Cost Explorer

Debug Checklist

1. Identity: aws sts get-caller-identity
2. Region: echo $AWS_REGION
3. Permissions: Check IAM
4. CloudTrail: Audit logs

Recovery Procedures

Compromised Key

1. Disable key immediately
2. Review CloudTrail
3. Rotate credentials
