Build a multi-agent music production pipeline on Amazon Bedrock AgentCore Runtime Instances

As organizations move from single-purpose agents to multi-agent systems, the infrastructure requirements change. A lone agent handling customer queries can run in a serverless environment with short-lived sessions. But when you need three agents collaborating on a creative workflow that spans several days, sharing context and building on each other’s output, serverless sessions that cap at a few hours don’t cut it.

In this post, we walk through deploying a music production pipeline: One agent runs a generative audio model on the instance’s own GPU. The other two open the .wav file it wrote, off a shared volume. By the end, you will have a track you can play. You will also have learned how to create capacity providers, deploy agents from different artifact types, orchestrate agent-to-agent collaboration using shared sessions, and persist workflows across multiple days.

Amazon Bedrock AgentCore offers two compute options for hosting agents. MicroVMs are the serverless option: fast cold starts, session isolation, and consumption-based pricing. Runtime Instances are the new option: AWS managed EC2 infrastructure for persistent, long-running agent workflows. Both use the same runtime…
