Demonstrates Amazon Application Recovery Controller (ARC) for automated cross-region failover.

• ARC Cluster: Multi-region control plane
• Routing Controls: Primary and secondary traffic controls
• Region Switch Plan: Automated failover workflows
• Simple Application: Demo app with ARC integration

# Deploy ARC infrastructure
aws cloudformation create-stack --stack-name arc-complete-demo \
  --template-body file://combined-arc-template.yaml \
  --capabilities CAPABILITY_IAM

# Deploy simple application
aws cloudformation create-stack --stack-name arc-simple-app \
  --template-body file://simple-app-template.yaml \
  --parameters ParameterKey=PrimaryRoutingControlArn,ParameterValue=<routing-control-arn>

# Test application
curl http://<app-url>:5000/health

# Simulate outage
python simulate_outage.py

• combined-arc-template.yaml - ARC cluster, controls, and region switch plan
• simple-app-template.yaml - Simple Flask application
• deploy-cloudformation.sh - Deployment script
