//firecracker-microvm.github.io"Firecracker is an alternative to QEMU that is purpose-built for running serverless functions and containers safely and efficiently, and nothing more. Firecracker is written in Rust, provides a minimal required device model to the guest operating system while excluding non-essential functionality (only 5 emulated devices are available: virtio-net, virtio-block, virtio-vsock, serial console, and a minimal keyboard controller used only to stop the microVM). This, along with a streamlined kernel loading process enables a < 125 ms startup time and a < 5 MiB memory footprint."

- Firecracker’s language of choice: Rust. Does this surprise you? It shouldn’t; Firecracker has roots in crosvm – the Chrome OS virtual machine monitor, which was written in Rust. Virtual machines written in Rust benefit from the language’s memory safety.
- Windows support? Not here. Firecracker is a Kernel-based virtual machine. It can only support Linux kernel v4.14 and higher.
Firecracker – Lightweight Virtualization for Serverless Computing @ aws blog
- "Secure – Firecracker uses multiple levels of isolation and protection, and exposes a minimal attack surface.
- High Performance – You can launch a microVM in as little as 125 ms today (and even faster in 2019),
- Battle-Tested – Firecracker has been battled-tested and is already powering multiple high-volume AWS services including AWS Lambda and AWS Fargate.
- Low Overhead – Firecracker consumes about 5 MiB of memory per microVM. You can run thousands of secure VMs with widely varying vCPU and memory configurations on the same instance.
- Open Source – Firecracker is an active open source project."
