### AI overview

This AWS post explains how to build a multi-region active-active architecture with Amazon CloudFront VPC origins. It describes geo-based, weighted, and session-affinity routing, along with automated origin failover, while keeping backend resources private inside Amazon VPC.

### Source excerpt

Introduction Building a multi-region active-active architecture with Amazon CloudFront requires careful coordination of traffic routing to address performance, traffic management, and session consistency requirements, along with automated failover to maintain availability during regional events. In November 2024, AWS released Amazon CloudFront VPC origins, which provides direct connectivity to private resources within your Amazon VPC without [...]
