AWS Lambda MicroVMs

Short summary

AWS Lambda MicroVMs use Firecracker virtualization to spin up full containerized micro virtual machines with 8-hour max execution, dedicated network endpoints (HTTP, gRPC, WebSocket, SSE), SSH access, and stateful persistence across suspensions. Cold starts take ~125ms. Use cases include ETL pipelines, ML training, large compilations, overnight tests, and ephemeral dev environments.
