Lambda adds Firecracker‑based MicroVMs for secure, stateful serverless sandboxes
AWS Lambda now offers MicroVMs, lightweight Firecracker‑based VMs that give each user a fully isolated, stateful sandbox with near‑instant start‑stop. This bridges the gap between containers and functions, letting AI assistants, interactive notebooks, and other multi‑tenant apps run untrusted code safely without custom virtualization overhead.
