Today, Amazon Web Services (AWS) is announcing Firecracker, new virtualization and open source technology that enables service owners to operate secure multi-tenant container-based services by combining the speed, resource efficiency, and performance enabled by containers with the security and isolation offered by traditional VMs. Firecracker implements a virtual machine manager (VMM) based on Linux’s Kernel-based Virtual Machine (KVM), and provides a RESTful API to create and manage microVMs with any combination of vCPU and memory to match application requirements. Firecracker is built with minimal device emulation that enables faster startup time, provides a reduced memory footprint for each microVM, and offers a trusted sandboxed environment for each container.
