Multi-Agent Systems Just Got Interoperable on AWS

AWS just dropped a neat trick for building multi-agent systems that actually play nice together: the Agent-to-Agent (A2A) protocol lets your LangChain orchestrator on Amazon ECS chat with Strands agents on Amazon Bedrock AgentCore without either side caring about the other's framework. Think of it as OAuth-authenticated handshakes between agents across organizational boundaries—no SDK lock-in required.
