AWS introduced Lambda MicroVMs, a serverless compute model that offers virtual machine isolation, near-instant startup, and the ability to suspend and resume workload state for up to 8 hours. This supports securely running multi-tenant applications executing code from users or AI, with no compromise between isolation, speed, and state retention.
Built on Firecracker virtualization, Lambda MicroVMs enable developers to assign isolated compute environments per user or job, accessible via dedicated HTTP-based URLs. This innovation benefits use cases such as coding environments and data analytics by improving security and performance without requiring users to manage underlying virtualization infrastructure.
