AWS Transit Gateway Adds Policy-Based Routing
🔧 AWS Transit Gateway now supports Policy-Based Routing (PBR), allowing forwarding decisions based on packet attributes such as source and destination IPs, ports, and protocol instead of destination alone. PBR reduces the need for complex multi-VPC architectures and extra routing hops by enabling administrators to attach policy tables to Transit Gateway attachments and define ordered rule sets. Rules classify traffic and direct matches to specified route tables using first-match-wins logic, supporting traffic steering, inspection, and environment isolation. PBR is available in all commercial AWS Regions where Transit Gateway is offered and can be configured via the Console, CLI, or SDK with no additional charge beyond standard Transit Gateway fees.
