Firecracker
FundedSecure, fast microVMs for efficient serverless and container workloads
About Firecracker
Firecracker is a virtualization technology designed for deploying secure, multi-tenant container and function-based services using lightweight virtual machines called microVMs. Developed by Amazon Web Services, it enables enterprises to run workloads with enhanced security and isolation compared to traditional VMs, while maintaining the speed and resource efficiency typical of containers. Firecracker is optimized for cloud infrastructure environments requiring rapid startup times and high-density workload packing.
Targeted at enterprises running serverless computing and containerized applications, Firecracker offers a minimalist virtual machine monitor built on Linux KVM that reduces memory footprint and attack surface. It supports fast microVM creation rates and fine-grained resource control through built-in rate limiters. Firecracker's design facilitates secure multi-tenant environments by isolating workloads with both virtualization and Linux user-space security barriers, making it suitable for cloud providers and organizations focused on secure, scalable infrastructure deployment.
