AWS publishes cross-account A2A multi-agent reference architecture using LangChain and Strands
AWS provides a deployed reference architecture showing how the Agent-to-Agent (A2A) protocol can connect LangChain-based enterprise orchestrators with Strands Agents–based SaaS agents across separate AWS accounts using OAuth/OIDC, Amazon Cognito, Bedrock AgentCore, API Gateway, ECS/Fargate and Agent Cards. The post includes implementation patterns, three Jupyter notebooks to deploy the system, and an end-to-end test; A2A is now a Linux Foundation project and AWS is listed among its supporters.
KEY POINTS
- AWS provides a deployed reference architecture showing how the Agent-to-Agent (A2A) protocol can connect LangChain-based enterprise orchestrators with Strands Agents–based SaaS agents across separate AWS accounts using OAuth/OIDC, Amazon Cognito, Bedrock AgentCore, API Gateway, ECS/Fargate and Agent Cards.
- The post includes implementation patterns, three Jupyter notebooks to deploy the system, and an end-to-end test; A2A is now a Linux Foundation project and AWS is listed among its supporters.
- This matters because A2A plus standardized auth lets organizations build interoperable, cross-boundary agent integrations without bespoke per-customer code, lowering integration cost and friction.
