Build a Serverless A2A Gateway on AWS for Agent Discovery, Routing, and Access Control
Decision Brief
What changedA blog on AWS Machine Learning Blog demonstrates how to build a serverless A2A gateway on AWS, hosting multiple agents under a single domain via path-based routing /agents/{agentId}, with standard A2A clients working without modification.
Why it mattersAI builders need to know how to leverage the A2A protocol and serverless architecture for unified agent discovery, routing, and access control to improve deployment efficiency and security of agent systems.

This article guides developers in building an A2A gateway using AWS serverless services like API Gateway and Lambda, supporting Agent Discovery, Routing, and Access Control. The core design uses path /agents/{agentId} to centralize multiple agents under a single domain, allowing standard A2A clients to communicate with any agent without changes. This architecture reduces management complexity, enhances scalability, and simplifies cross-agent permission control.
