AWS Transit Gateway adds Policy-Based Routing for granular traffic control

infraawsengineer
feature

AWS Transit Gateway now supports Policy-Based Routing (PBR), allowing network administrators to direct traffic based on multiple packet attributes, not just destination IP. This feature simplifies network architectures by eliminating the need for complex multi-VPC setups for traffic steering and workload isolation. It's now available in all commercial AWS Regions and can be configured via the AWS Management Console, CLI, or SDK.

  • Policy-Based Routing now available on AWS Transit Gateway

    Transit Gateway now supports Policy-Based Routing (PBR), enabling forwarding decisions based on packet attributes like source/destination IP, ports, and protocols, not just destination IP. This eliminates the need for multi-VPC architectures to steer traffic or isolate workloads.

Enhancements (1) ›
  • Simplified traffic steering and workload isolation

    PBR extends Transit Gateway's native routing, allowing classification and direction of traffic inline without additional infrastructure. This is particularly useful for steering sensitive workloads through inspection appliances or routing application traffic over specific connections based on defined rules.

Notes (1) ›
  • Configuration and availability

    Customers associate a policy table with a Transit Gateway attachment and define ordered rules for traffic classification and routing. PBR is available in all commercial AWS Regions, incurring no additional charge beyond standard Transit Gateway fees.
