MicroVMs: Run isolated sandboxes with full lifecycle control

AWS Lambda MicroVMs introduces a new serverless compute primitive that combines VM-level isolation with sub-second launch times and stateful execution for multi-tenant applications requiring isolated sandboxes—addressing a critical gap where traditional VMs offer isolation but slow startup, containers risk security with shared kernels, and serverless functions lack state retention. This capability enables CIOs to support emerging use cases like AI code assistants, interactive development environments, and user-generated code execution without forcing engineering teams to build custom virtualization infrastructure, reducing both operational complexity and time-to-market. The service leverages proven Firecracker technology already running trillions of Lambda invocations monthly, providing enterprise-grade operational maturity with minimal infrastructure management overhead.
