AWS RTB Fabric now supports configurable Availability Zone affinity
AWS RTB Fabric has launched configurable Availability Zone (AZ) affinity for responder gateways, allowing users to control how partners connect. This feature enables AdTech companies to route connections either to the requester's own AZ or to any AZ spanned by the gateway. The change helps Demand-side Platforms (DSPs) and Supply-side Platforms (SSPs) utilize their infrastructure more efficiently by optimizing gateway capacity across AZs. This new capability is generally available in all AWS Regions where RTB Fabric is offered, without additional charges.
