Amazon Bedrock AgentCore: modular agent infrastructure on AWS

Overview

AgentCore works with "LangChain, OpenAI Agents SDK, Claude Agent SDK, Strands SDK, or your own". Services include Runtime (with session isolation in microVMs), Gateway, Memory, Identity, Policy, Observability through CloudWatch, Evaluations, Browser, Code Interpreter and an AWS Agent Registry.

How it coordinates agents

AgentCore hosts and connects agents; coordination logic comes from the framework you deploy. A2A on Runtime lets AgentCore agents call and be called by other A2A agents.

Governance

Identity, Policy ("access policies verified by automated reasoning"), Observability, Evaluations and microVM session isolation.
