Firecracker is an open source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services that provide serverless operational models. Firecracker runs workloads in lightweight virtual machines, called microVMs, which combine the security and isolation properties provided by ha...
To get started with Firecracker, download the latest release binaries or build it from source.
You can build Firecracker on any Unix/Linux system that has Docker running (we use a development container) and bash installed, as follows:
The Firecracker binary will be placed at build/cargo_target/${toolchain}/debug/firecracker. For more information on building, testing, and running Firecracker, go to the quickstart guide.
The overall security of Firecracker microVMs, including the ability to meet the criteria for safe multi-tenant computing, depends on a well configured Linux host operating system. A configuration that we believe meets this bar is included in the production host setup document.
Firecracker is already running production workloads within AWS, but it's still Day 1 on the journey guided by our mission. There's a lot more to build and we welcome all contributions.
To contribute to Firecracker, check out the development setup section in the getting started guide and then the Firecracker contribution guidelines.
New Firecracker versions are released via the GitHub repository releases page, typically every two or three months. A history of changes is recorded in our changelog.
The Firecracker release policy is detailed here.
Firecracker's overall architecture is described in the design document.
Firecracker consists of a single micro Virtual Machine Manager process that exposes an API endpoint to the host once started. The API is specified in OpenAPI format. Read more about it in the API docs.
The API endpoint can be used to:
•Configure the microvm by:
•Setting the number of vCPUs (the default is 1).
•Setting the memory size (the default is 128 MiB).
•Configuring a CPU template.
•The pl031 RTC device on aarch64 does not support interrupts, so guest programs which use an RTC alarm (e.g. hwclock) will not work.
Firecracker's performance characteristics are listed as part of the specification documentation. All specifications are a part of our commitment to supporting container and function workloads in serverless operational models, and are therefore enforced via continuous integration testing.
Kata Containers also supports multiple hypervisors including QEMU, Cloud-Hypervisor and Firecracker and integrates with the containerd project among others. The Kata Containers community is stewarded by the Open Infrastructure Foundation, which supports the development and adoption of open infrastructure globally.

26 nov 2018 · 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), making it ideal for many types of workloads, including those that are transient or short-lived.
9 dic 2019 · AWS Firecracker是一款由 AWS开源的轻量级虚拟化运行环境，客户可以在 AWS 云上和本地环境中使用它。 Firecracker MicroVM 同时具备传统虚拟机的安全性和工作负载隔离能力以及容器的速度和资源利用率。 运行在为 Firecracker 优化过的 Amazon 裸金属 EC2 服务器上的 MicroVM是多租户容器服务的理想选择，可以为最新的微服务或无服务器架构的现代应用提供方便、敏捷的开发和部署环境。 计算机虚拟化历史. 为了便于读者理解，本文在正式介绍 Firecracker 前，先回顾一下虚拟化的发展，同时按照笔者的理解对涉及到的一些专业术语做一下翻译和解释：
