About This Architecture

Multi-AZ Java application architecture on AWS ECS with DAX caching and DynamoDB for resilient, low-latency data access. Users route through WAF and API Gateway to an Application Load Balancer, which distributes traffic across ECS clusters running Java applications in separate availability zones. Each ECS cluster connects to a DAX cluster for in-memory caching, backed by DynamoDB tables with cross-AZ replication for fault tolerance. CloudWatch and X-Ray provide observability, while ECR stores container images and Secrets Manager secures credentials. Fork this diagram to customize subnets, scaling policies, or add additional AWS services like RDS or ElastiCache for your workload.

People also ask

How do I architect a highly available Java application on AWS ECS with caching and database replication across multiple availability zones?

This diagram shows a production-grade pattern: Java applications run in ECS clusters across two availability zones behind an ALB, with DAX clusters providing in-memory caching for DynamoDB queries. DynamoDB tables replicate across AZs for automatic failover, while WAF and API Gateway protect the entry point, and CloudWatch plus X-Ray enable full observability.
