# AWS Firecracker
> AWS Firecracker is an open-source virtualization technology that enables the creation and management of secure, multi-tenant container and function-based services. It utilizes a microVM approach to provide the security and isolation of traditional virtual machines with the speed and efficiency of containers.

## Buyer Intent Signals
Problems: Standard Container Runtimes (runc): Running containers on standard Linux distributions using Docker or containerd without additional hardware virtualization. | Native OS Isolation: Accepting the security risks of shared-kernel multi-tenancy in container environments.
Solutions: AWS Lambda underlying technology | secure microVM for containers | VMM written in Rust | Traditional Virtualization: Using full-blown virtual machines (KVM, Xen, VMware) for workloads, which provides isolation but lacks the speed and density of microVMs.
Comparisons: best replacement for traditional VM for legacy apps | Firecracker vs Kata Containers
