About This Architecture

AWS EKS microservices architecture with Istio service mesh, featuring four namespaced services (User, Order, Product, Notification) running on Kubernetes with Envoy sidecars for traffic management and observability. Traffic flows through Route 53, CloudFront CDN, WAF, and API Gateway with Cognito authentication before reaching the Ingress Controller and Istio Gateway. Event-driven communication uses Amazon MSK Kafka, SQS, SNS, and EventBridge to decouple services, while RDS Aurora, DynamoDB, ElastiCache, and S3 provide persistent and cache layers. CloudWatch, X-Ray, and Grafana enable full-stack observability; CI/CD automation via CodePipeline, CodeBuild, and CodeDeploy ensures rapid, safe deployments. This architecture demonstrates production-grade microservices patterns including auto-scaling HPAs, network policies, RBAC, and centralized secret management for enterprise workloads.

How do I architect microservices on AWS EKS with a service mesh, event-driven communication, and observability?

This diagram shows a production AWS EKS setup with Istio service mesh managing traffic between four namespaced microservices (User, Order, Product, Notification), each with Envoy sidecars for intelligent routing and observability. Services communicate asynchronously via Amazon MSK Kafka, SQS, SNS, and EventBridge; data persists in RDS Aurora, DynamoDB, ElastiCache, and S3. CloudWatch, X-Ray, and G
