About This Architecture

Multi-AZ three-tier web architecture spanning AWS regions with WAF, CloudFront CDN, Route 53, and API Gateway protecting the edge. Traffic routes through Application Load Balancers to compute options including EC2 t3.medium, ECS Fargate, and Lambda across isolated public, application, and data subnets in two availability zones. RDS Primary with Multi-AZ standby and DynamoDB with cross-AZ replication ensure database resilience and fault tolerance. This architecture demonstrates AWS best practices for high availability, auto-scaling, and disaster recovery—critical for production workloads requiring 99.99% uptime.

How do I design a highly available three-tier web application on AWS across multiple availability zones?

This diagram shows a production-ready AWS architecture spanning two AZs with WAF and CloudFront protecting the edge, Route 53 and API Gateway routing traffic, Application Load Balancers distributing to EC2, ECS Fargate, and Lambda compute options, and RDS Multi-AZ with DynamoDB replication ensuring database resilience. Each tier is isolated in separate subnets, enabling independent scaling and sec
