AWS RTB Fabric supports custom domains for real-time bidding workloads

AWS RTB Fabric now supports custom domains for real-time bidding transactions received through external links. This capability helps advertising technology (AdTech) companies preserve their public endpoints and use owned domains—without requiring their partners to update their endpoint configurations.

Endpoints (like bid.company.com/path) for real-time bidding workloads are typically representative of established, long-term traffic contracts. Modifying these endpoints requires coordination across multiple organizations, applications, and domains—which can slow set up between AdTech partners. With custom domains, AdTech companies can use their own domain name system (DNS) and configure canonical name (CNAME) public endpoints. They can also define routing rules to direct traffic to specific RTB Fabric links based on URL patterns. For example, a demand side platform (DSP) or supply side platform (SSP) can point their existing DNS server to RTB Fabric and define routing rules to map URL patterns to specific traffic sources. This allows them to seamlessly route all partner traffic through RTB Fabric without altering their own endpoint configurations. Supply partners also do not need to change their configurations.

AWS RTB Fabric helps you connect with your AdTech partners such as Amazon Ads, GumGum, Kargo, MobileFuse, Sovrn, TripleLift, Viant, Yieldmo, and more in three steps while delivering single-digit millisecond latency through a private, high-performance network environment. RTB Fabric reduces standard cloud networking costs by up to 80% and does not require upfront commitments. This capability is available in all AWS Regions where AWS RTB Fabric is supported: US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Tokyo), Europe (Frankfurt), and Europe (Ireland). To learn more, visit the documentation or AWS RTB Fabric product page.
