Technical Architecture Guide
Summary
This article explains how to use Amazon S3 Files to orchestrate multi-agent AI architectures by providing a shared POSIX file system for agent handoffs. This approach uses files as persistent working memory to avoid the high costs and quality degradation associated with excessively large prompts.
Highlights
Multi-agent systems use files as working memory to bypass context window limits and reduce prompt inflation.
Amazon S3 Files provides POSIX semantics, allowing agents to use standard file operations like open() and write() instead of complex API calls.
The architecture supports seamless integration across various AWS services including Lambda, EC2, EKS, and Bedrock AgentCore Runtime.
Workflow automation is driven by S3 event notifications and SQS to trigger agents when new data arrives.
