About This Architecture

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.

How do I architect a highly available AWS application using CloudFront, ALB, and ECS Fargate across multiple availability zones?

This diagram shows a production-grade pattern: CloudFront distributes user traffic to three Application Load Balancers spanning AZ-1, AZ-2, and AZ-3. Each ALB routes to ECS Fargate tasks in private subnets, with NAT Gateways enabling secure outbound connectivity. This design ensures automatic failover, zero single points of failure, and compliance with AWS well-architected framework principles.
