About This Architecture

AWS Command Center is a multi-layer API monitoring and mock server platform combining CloudFront CDN, API Gateway with WAF, and EKS-hosted microservices for intelligent request routing. The architecture routes traffic through JWT authentication, RBAC/IAM policies, and a virtualization decision engine that dynamically switches between real APIs and WireMock mock servers based on scenario configuration. RDS PostgreSQL stores API registrations and stub definitions while ElastiCache Redis caches health metrics; EventBridge and Lambda functions asynchronously execute health checks, API capture, and cleanup tasks. This design enables teams to test API integrations, simulate failure scenarios, and validate client resilience without impacting production systems.

How do I build an API mocking and monitoring platform on AWS that routes requests between real and virtualized services?

This diagram shows a complete AWS Command Center architecture that uses API Gateway for authentication and routing, EKS to host WireMock mock servers, and a virtualization decision engine to dynamically switch between real APIs and stubs. EventBridge and Lambda automate health checks and stub creation, while RDS and ElastiCache provide persistent storage and caching for API metadata and health met
