AWS Guide Shows How to Migrate Healthcare AI Agents from ECS to Bedrock AgentCore

AWS has published a migration guide detailing how to move a production healthcare AI agent from self-managed Amazon ECS containers to its managed Bedrock AgentCore runtime. The original ECS setup coordinated three specialized foundation models — for triage, diagnosis, and treatment planning — alongside vector-based knowledge retrieval, all requiring custom state management and observability code. Bedrock AgentCore replaces this with a declarative YAML or JSON configuration, automatically handling model orchestration, state persistence, retries, and CloudWatch logging. The trade-off is reduced operational burden at the cost of visibility, as teams lose access to container-level metrics and cannot customize the underlying execution environment. AWS positions AgentCore as suitable when managed convenience outweighs the need for fine-grained infrastructure control.
