Resource Cleanup

AWS Resource Cleanup

Properly clean up all Weather Platform resources to avoid ongoing charges. Amplify’s CloudFormation-based infrastructure makes cleanup straightforward with simple commands.

Quick Cleanup Commands

Development Sandbox Cleanup

# Single command to delete entire sandbox environment
npx ampx sandbox delete --profile ws1-amplify

Production Environment Cleanup

# Delete production deployment
npx ampx pipeline-deploy --branch main --appId <your-app-id> --delete --profile ws1-amplify

What Gets Cleaned Up

Amplify automatically removes:

• All CloudFormation stacks
• Lambda functions and their execution roles
• S3 buckets and contents (if configured for auto-deletion)
• Cognito User Pools and Identity Pools
• AWS Glue databases, crawlers, and jobs
• CloudFront distributions
• EventBridge rules
• IAM roles and policies created by Amplify

Manual Cleanup Required

Some resources may need manual deletion:

IoT Core Resources

# Delete IoT policies
aws iot delete-policy --policy-name WeatherStationPolicies --profile ws1-amplify
aws iot delete-policy --policy-name WeatherPlatformPubSubPolicy --profile ws1-amplify

# Delete IoT Rule
aws iot delete-topic-rule --rule-name WeatherTelemetryToS3Rule --profile ws1-amplify

# Delete Thing Group
aws iot delete-thing-group --thing-group-name ITeaWeatherHub --profile ws1-amplify

Data Lake Bucket

# Empty and delete data lake bucket
aws s3 rm s3://itea-weather-data-lake-storage-yourname --recursive --profile ws1-amplify
aws s3 rb s3://itea-weather-data-lake-storage-yourname --profile ws1-amplify

Verification Steps

After cleanup, verify all resources are deleted:

1. AWS Console Verification:

   • Amplify: Check no apps remain
   • CloudFormation: Verify stacks are deleted
   • S3: Confirm buckets are removed
   • Lambda: Check no functions remain
   • Cognito: Verify User Pools are deleted

2. CLI Verification:

   # Check remaining S3 buckets
   aws s3 ls --profile ws1-amplify | grep weather
   
   # Check remaining Lambda functions
   aws lambda list-functions --profile ws1-amplify | grep weather
   
   # Check CloudFormation stacks
   aws cloudformation list-stacks --profile ws1-amplify | grep amplify
   

Cost Monitoring

Post-cleanup verification:

1. AWS Cost Explorer: Check for any remaining charges
2. Billing Dashboard: Monitor for unexpected costs over next few days
3. Budget Alerts: Set up alerts for unusual spending

Emergency Cleanup

If standard cleanup fails:

# Force delete CloudFormation stacks
aws cloudformation delete-stack --stack-name amplify-<app-name> --profile ws1-amplify

# List and manually delete remaining resources
aws resourcegroupstaggingapi get-resources --tag-filters Key=amplify:project-name --profile ws1-amplify
