Use Cases & Benefits
- Enables creation and management of secure, lightweight microVMs for running container and function workloads with minimal overhead.
- Combines hardware virtualization security with container speed and flexibility, reducing memory footprint and attack surface for improved performance and isolation.
- Use for deploying multi-tenant serverless functions with strong isolation and fast startup times in cloud environments.
- Use for integrating secure microVMs into container runtimes to enhance security and resource efficiency in container orchestration platforms.
- Use for building custom virtualized environments that require fine-grained resource control and minimal latency on Linux hosts.

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 hardware virtualization technology with the speed and flexibility of containers.
The main component of Firecracker is a virtual machine monitor (VMM) that uses the Linux Kernel Virtual Machine (KVM) to create and run microVMs. Firecracker has a minimalist design. It excludes unnecessary devices and guest-facing functionality to reduce the memory footprint and attack surface area of each microVM. This improves security, decreases the startup time, and increases hardware utilization. Firecracker has also been integrated in container runtimes, for example Kata Containers and Flintlock.
Firecracker was developed at Amazon Web Services to accelerate the speed and efficiency of services like AWS Lambda and AWS Fargate. Firecracker is open sourced under Apache version 2.0.
