Run isolated sandboxes with full lifecycle control: AWS Lambda introduces MicroVMs
AWS News Blog
AWS Lambda introduces MicroVMs, a new serverless compute primitive that lets developers run user or AI-generated code in isolated, stateful execution environments with VM-level isolation and near-instant launch times.
- Powered by Firecracker, the same technology behind 15 trillion monthly Lambda invocations
- Combines VM isolation, rapid launch/resume from snapshots, and stateful execution across sessions
- Automatically suspends idle MicroVMs to reduce costs while preserving full state for fast resume
- Supports up to 8 hours runtime, 16 vCPUs, 32 GB memory, and 32 GB disk per MicroVM
- Purpose-built for multi-tenant apps like AI coding assistants, code environments, analytics platforms, and game servers
- Available in US East, US West, Europe (Ireland), and Asia Pacific (Tokyo) regions
Lambda MicroVMs fills the gap between containers and VMs, enabling developers to safely run untrusted code without managing complex virtualization infrastructure.
