Migrating multi-model AI agents to Amazon Bedrock AgentCore runtime

Machine Learning Blog



This article demonstrates migrating a multi-model healthcare AI agent from self-managed Amazon ECS infrastructure to Amazon Bedrock AgentCore runtime, which automates container management and scaling.

  • AgentCore runtime handles container lifecycle, scaling, identity, and observability automatically
  • Agent orchestrates across three model backends: Amazon SageMaker AI, Amazon Bedrock, and containerized model servers
  • Uses Hugging Face smolagents framework with AgentCore decorator pattern for seamless integration
  • Deployment simplified to single CLI command with no changes to core agent logic
  • Includes vector-enhanced knowledge retrieval via Amazon OpenSearch Service for medical queries
  • Supports domain-specific models like BioM-ELECTRA for biomedical queries and Llama 3.1 for broader reasoning

AgentCore runtime enables teams to focus on agent development rather than infrastructure management while preserving multi-model orchestration capabilities.
