Multi-AZ CloudFront distribution routes traffic across three Application Load Balancers deployed in separate AWS availability zones, each fronting ECS Fargate tasks in private subnets. NAT Gateways in each AZ enable outbound internet connectivity for containerized workloads while maintaining security isolation. This architecture delivers fault tolerance, automatic failover, and geographic load distribution across us-east-1a, us-east-1b, and us-east-1c. Fork and customize this diagram on Diagrams.so to adapt subnet sizing, add RDS databases, or integrate AWS Secrets Manager for credential rotation.
