AWS 放出來的 open source 專案 Firecracker，也就是在 AWS 內打造安裝的 container 環境所使用的技術：「Firecracker – Lightweight Virtualization for Serverless Computing」。
High Performance – You can launch a microVM in as little as 125 ms today (and even faster in 2019), making it ideal for many types of workloads, including those that are transient or short-lived.
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.
看起來有機會在自己機器上跑看看 (i.e. 非虛擬環境)？跑之前要注意目前只支援 Intel 的硬體：
Firecracker currently supports Intel CPUs, with planned AMD and Arm support. Firecracker will also be integrated with popular container runtimes.
