Building a computer that can pause and resume in milliseconds: Inside the MicroVM architecture behind Managed Agents
DigitalOcean has launched 'Managed Agents' into public preview, utilizing a Firecracker microVM-based architecture. This system enables the checkpointing and restoration of running processes, memory states, and filesystem contexts for agentic workloads.
Verified State Diff
Impact & Verification Analysis
Developers building autonomous agents, AI-driven automation workflows, and enterprise users requiring stateful, ephemeral compute environments.
This architecture solves the 'cold start' and 'state loss' problem for AI agents, allowing for complex, multi-step tasks that require long-lived context without the overhead of maintaining idle, full-scale virtual machines.
Full Fact Overview
The architecture leverages Firecracker microVMs with KVM hardware virtualization to provide kernel-level isolation for agent sessions. By decoupling the session from the host, the platform enables near-instant state restoration through memory and disk checkpointing. The infrastructure is organized into 'cells'—region-scoped, self-contained units comprising a VPC, Kubernetes cluster, managed PostgreSQL, and hypervisor pools—to limit blast radiuses and improve fault isolation. This design allows for the persistence of in-memory indexes and active interpreters, which were previously lost when containers or VMs were destroyed to save resources.
