Multi-VPC network architecture spanning AWS Tokyo region (ap-northeast-1) with four isolated VPCs—ihome commercial, test environment, com_vpc, and windows_net—each with Internet Gateways and distributed subnets across availability zones. Traffic flows from the Internet through IGWs into respective VPCs, with EC2 instances, RDS databases (MySQL, CRM Portal, Aeon, Primax-Web), and EFS file systems deployed across ap-northeast-1a, ap-northeast-1c, and ap-northeast-1d. This architecture demonstrates VPC isolation for production, staging, and specialized workloads while maintaining independent data stores and compute resources per environment. Fork and customize this diagram on Diagrams.so to model your own multi-tenant or multi-environment AWS deployments in Tokyo or other regions. Consider adding VPC peering or Transit Gateway connections if cross-VPC communication is required.
