Outposts Rack Inter-VPC routing - AWS Outposts High Availability Design and Architecture Considerations

Outposts Rack Inter-VPC routing

Resources on two separate Outposts deployed in different VPCs can communicate each other across the customer network. Deploying this architecture enable you to route traffic Outposts-to-Outposts by your local on-premises and WAN networks adding routes towards the counterpart Outposts/VPC subnets.

Recommended practices for protecting against larger failure modes:

  • Deploy multiple Outposts anchored to multiple AZs and Regions.

  • Use separate VPCs for each Outpost in a multi-Outpost deployment.
