Firecracker is an open-source virtual machine monitor (VMM) developed by Amazon Web Services. It uses the Linux Kernel-based Virtual Machine (KVM) to create and manage lightweight virtual machines, known as microVMs.

Who is Firecracker designed for?

Firecracker is designed for services and developers creating secure, multi-tenant container and function-based services. It's suitable for applications requiring strong workload isolation combined with container-like speed and resource efficiency.

How does Firecracker differ from traditional virtual machines or containers?

Firecracker microVMs provide enhanced security and isolation superior to containers, while being significantly lighter and faster than traditional VMs. Its minimalist design reduces memory footprint, attack surface, and startup times by excluding unnecessary guest functionality.

When should one consider using Firecracker?

Firecracker should be considered for workloads requiring strong isolation similar to VMs but with the rapid startup and low overhead of containers. It is ideal for serverless functions, containerized services, and multi-tenant environments where security and resource efficiency are critical.

What operating systems can Firecracker run and on what hardware?

Firecracker can run Linux and OSv guests. It is generally available on 64-bit Intel, AMD, and Arm CPUs that support hardware virtualization.
