About This Architecture

Multi-AZ AWS EKS microservices architecture with Route 53, WAF, and Application Load Balancer routing traffic across Spring Boot services in two availability zones. Microservices communicate via Amazon MSK Kafka, persist data in RDS PostgreSQL and ElastiCache Redis, and scale automatically using HPA based on demand. The design isolates services into namespaces, distributes workloads across AZs for high availability, and integrates CloudWatch monitoring with IAM and Secrets Manager for security. Fork this diagram to customize pod counts, add additional microservices, adjust CIDR ranges, or document your own multi-tenant EKS deployment.

How do I design a highly available AWS EKS microservices architecture across multiple availability zones?

This diagram shows a production EKS cluster spanning us-east-1a and us-east-1b with Spring Boot microservices in isolated namespaces, Route 53 DNS, WAF protection, and ALB routing. Services communicate via Amazon MSK Kafka, store data in RDS PostgreSQL and ElastiCache Redis, and auto-scale using HPA. Multi-AZ deployment ensures fault tolerance and high availability.
