AWS RTB Fabric: Reinventing Ad Tech Infrastructure
Ari Paparo sits down with Sergio Serra, PM Lead for RTB Fabric at AWS, to discuss how Amazon is reinventing the foundations of programmatic advertising. The conversation outlines RTB Fabric’s ability to eliminate data egress costs and data balancing expenses, boost reliability with deterministic routing, and deploy a per-billion transaction pricing model tailored to ad tech. Serra describes a modular stack with built‑in rate limiting, filtering, and error masking designed for SSPs and DSPs, and highlights external connectivity beyond AWS’s backbone. The talk also touches launch partners and potential future expansion. Overall, the discussion frames RTB Fabric as a purpose-built infrastructure layer that could redefine the economics and performance of ad exchanges and real-time bidding in digital advertising.

AWS Unveils RTB Fabric: Revolutionizing Ad Tech Bidding
AWS launched RTB Fabric, a cloud infrastructure service designed for ad tech to streamline real-time bidding in the cloud. The service promises single-digit-millisecond latency and an 80% discount on data transferred out of AWS, aiming to ease integrations with ecosystem and infrastructure partners. AWS executives emphasize easier data integrations across publishers, SSPs, and DSPs, with a private AWS network and a marketplace of RTB Fabric clients to shorten integration timelines from days or weeks to hours. TripleLift, an SSP, has begun using RTB Fabric to connect with four partners including Amazon DSP, reporting latency reductions of 15–20% on data requests and substantial cost savings. The rollout comes as ad tech vendors invest in AI and cloud infrastructure; AWS states the launch is not related to a recent outage.
AWS Launches RTB Fabric for Programmatic Ad Infrastructure
Amazon Web Services announced AWS RTB Fabric, a specialized cloud service aimed at the programmatic advertising market. Launched publicly after a private beta, AWS RTB Fabric provides a private network optimized for real-time bidding workloads, promising single-digit millisecond latency and up to 80% lower networking costs. AWS positions the product as foundational infrastructure to resolve the speed-vs-cost trade-off that has constrained ad tech migration to the cloud. AWS framed the launch as part of a broader Amazon advertising push and cited early adopters such as TripleLift and Viant. The company is actively courting publishers and ad-tech vendors as the industry adapts to a cookieless future and seeks greater efficiency in programmatic auctions.
Revolutionizing Real-Time Bidding with Agentic RTB Framework
IAB Tech Lab published the Agentic RTB Framework (ARTF) v1.0 and opened it for public comment. ARTF defines a container-based, agent-powered architecture for real-time bidding that enables third-party service agents to be deployed into host platforms with standardized interfaces, performance guarantees, and security controls. The specification requires agents to be OCI-compliant containers manageable via Kubernetes, Docker Compose, or cloud container services (e.g., Amazon ECS), to communicate over high-performance protocols such as gRPC or MCP using protobuf serialization, and to operate without external network ingress/egress except for orchestrator communications. The framework aims to reduce integration overhead, preserve host control of data and SLAs, support composable bid-processing pipelines, and enable use cases like user-data collaboration, fraud detection, bid optimization, and supply-path optimization. Several industry companies participated in developing the specification.
