Building a serverless A2A gateway for agent discovery, routing, and access control
AWS demonstrates a serverless A2A gateway on AWS that enables multi-agent discovery, routing, and access control via path-based routing.
- AWS demonstrates a serverless A2A gateway using path-based routing to host multiple agents under a single domain.
- Standard A2A clients require no modifications to interact with agents via the gateway.
- The solution leverages AWS Lambda and API Gateway for scalable, cost-efficient agent management.
- Step-by-step guides and code samples are provided for implementation.
AWS has published a technical guide detailing the construction of a serverless A2A (Agent-to-Agent) gateway on AWS infrastructure. The solution leverages AWS Lambda, API Gateway, and other serverless services to host multiple agents behind a single domain using path-based routing (e.g., /agents/{agentId}). This approach allows standard A2A clients to interact with multiple agents without requiring modifications to their existing implementations.
The gateway abstracts agent discovery, routing, and access control, enabling developers to manage agent interactions at scale while reducing operational overhead. By using serverless components, the architecture automatically scales with demand and incurs costs only for actual usage, making it a cost-effective solution for deploying multi-agent systems. The post includes step-by-step instructions, sample code, and architectural diagrams to guide implementation.
This development aligns with the growing trend of agentic AI systems, where multiple specialized agents collaborate to perform complex tasks. The serverless A2A gateway provides a standardized way to integrate and manage these agents, potentially accelerating the adoption of agentic workflows in production environments.
