About This Architecture
Enterprise banking platform architecture spanning three AWS VPCs with segregated experience, process, and system layers, integrating on-premise systems via hybrid connectivity. Traffic flows through Route 53 and CloudFront to API Gateway endpoints protected by WAF and Shield, with OAuth2/mTLS authentication via Cognito and partner integrations. Middleware layer orchestrates workloads across Step Functions, ECS/EKS, EventBridge, and Glue ETL, while backend layer serves RDS Aurora, DynamoDB, and S3 through VPC endpoints and private subnets. Governance spans CloudWatch, X-Ray, CloudTrail, GuardDuty, and cross-account observability for compliance and security monitoring.
