Building a serverless A2A gateway for agent discovery, routing, and access control
AWS just shipped the infrastructure pattern every multi-agent startup needs: serverless A2A gateways with built-in discovery and access control.
Why it matters
As agent deployments scale from pilots to production, operators need standardized patterns for routing, discovery, and security across multiple agents. AWS's serverless A2A gateway addresses this operational necessity—a signal that multi-agent architectures are moving from research to enterprise deployment.
