VPC to VPC connectivity - Building a Scalable and Secure Multi-VPC AWS Network Infrastructure

VPC to VPC connectivity

Customers can use two different VPC flow patterns to set up multi-VPC environments: many to many, or hub and spoke. In the many-to-many approach, the traffic between each VPC is managed individually between each VPC. In the hub-and-spoke model, all inter-VPC traffic flows through a central resource, which routes traffic based on established rules.
