AWS EKS microservices architecture with multi-AZ deployment across public and private subnets, featuring API Gateway, Auth, Business Logic, Data, and Cache service pods orchestrated by Kubernetes. Traffic flows through Internet Gateway, WAF, and ALB to EKS node groups in Availability Zones A and B, with HPA auto-scaling triggered by SQS and SNS events. Data persistence uses RDS Primary/Standby (db.r5.large) for relational data, ElastiCache with replicas for caching, and S3 for file storage, while CloudWatch, X-Ray, CloudTrail, IAM, and Secrets Manager provide observability, security, and compliance. This production-grade pattern demonstrates zero-trust networking, automated scaling, and disaster recovery best practices for containerized workloads.
