Live Actor Migration in Agent Substrate: Moving State Across Workers

Short summary

This tutorial demonstrates live actor migration in Agent Substrate, showing how AI agent state can be suspended, checkpointed to object storage, and resumed on a different Kubernetes worker with full context preserved. It covers multi-tenant actor isolation using actorspaces, cost reduction via suspend/resume (up to 90%), and cold-boot optimization from minutes to seconds. The hands-on walkthrough uses kubectl commands on GKE or kind to prove that agent state travels with the actor rather than being tied to any specific pod.

• •Agent Substrate suspends idle actors to cut costs by up to 90% and reduce startup from minutes to seconds
• •Actor state is checkpointed to object storage and restored on any free worker, proving pods are cattle while actor state persists
• •Multi-tenant isolation via actorspaces keeps same-ID actors completely separate across tenants
