About This Architecture

Multi-AZ AWS microservices architecture with Route 53, CloudFront, WAF, and API Gateway routing traffic to ECS-based User, Order, and Product services across two availability zones. Services communicate via EventBridge and SQS, with RDS Aurora primary-standby replication, ElastiCache Redis caching, and DynamoDB for NoSQL workloads. CloudWatch and X-Ray provide observability, while Cognito handles authentication and Secrets Manager secures credentials. Fork this diagram to customize subnets, add additional AZs, or swap ECS for Fargate and Lambda for serverless compute patterns.

How do I design a highly available AWS microservices architecture with multi-AZ failover and event-driven communication?

This diagram shows a production-grade pattern using Route 53 for DNS failover, CloudFront and WAF for edge protection, and API Gateway for request routing to ECS microservices across two AZs. RDS Aurora primary-standby replication, ElastiCache Redis replicas, and EventBridge-to-SQS-to-Lambda event chains ensure resilience and decoupled service communication.
