AWS shows a serverless A2A gateway for agent discovery and access control

AWS published a machine-learning post showing how to build a serverless A2A gateway for agent discovery, routing, and access control. The pattern hosts multiple agents behind a single domain using path-based routing while standard A2A clients continue to work. It is a concrete infrastructure story for multi-agent enterprise deployment.

Key details: The pattern hosts multiple agents behind one domain, It supports discovery, routing, and access control, AWS says standard A2A clients can work without modification.

Why it matters: Agent interoperability needs routing and access-control plumbing before multi-agent systems can be run safely in companies.
