About This Architecture

Multi-AZ e-commerce architecture spanning two AWS availability zones with CloudFront CDN, AWS WAF, and Route 53 for global traffic distribution and DDoS protection. Application tier uses ALB routing to EC2 t3.medium instances, ECS Fargate containers, and Lambda functions across both AZs, with ElastiCache Redis and dual database backends (DocumentDB and RDS MySQL) for caching and persistence. This design eliminates single points of failure through cross-AZ replication of cache and database layers, ensuring zero-downtime deployments and automatic failover. Fork and customize this diagram on Diagrams.so to match your specific compute ratios, database instance types, or regional requirements. The architecture demonstrates AWS best practices for fault tolerance, cost optimization, and observability using CloudWatch and X-Ray.

How do I design a highly available e-commerce platform on AWS that spans multiple availability zones with automatic failover?

This diagram shows a production-grade multi-AZ architecture using CloudFront and WAF for edge protection, Route 53 for DNS failover, and ALB distributing traffic to compute (EC2, ECS Fargate, Lambda) across us-east-1a and us-east-1b. Database and cache layers replicate across AZs—RDS MySQL Primary/Standby, DocumentDB Primary/Replica, and ElastiCache Redis Primary/Replica—ensuring zero data loss an
