AWS Bedrock Multi-Agent Collaboration is a managed service feature that enables you to orchestrate multiple AI agents powered by foundation models to work together on complex tasks. You configure agent personas with specific roles, define messaging schemas for communication, and set shared memory for context retention. During execution, agents can request data from downstream sources, delegate subtasks, and aggregate each other's outputs. This collaborative approach supports iterative reasoning loops, improves task accuracy, and allows dynamic scaling of agents based on workload. Integrated with AWS console, CLI, and SDKs, the service offers monitoring dashboards to visualize agent interactions and performance metrics, simplifying development and operational oversight of intelligent multi-agent workflows.
