Firecracker
A lightweight microVM technology developed by AWS that can launch a complete microVM in 125 milliseconds. It combines Linux kernel cgroups and namespaces to provide resource isolation and is used in scenarios such as AI Agent sandboxes.
Core Facts
AWS Firecracker is a representative MicroVM solution that achieves millisecond-level startup speeds through a minimized virtual device model.
Firecracker microVM is the lightweight virtual machine technology underlying AWS Lambda.
Mainstream sandbox solutions are typically based on container (e.g., Docker) or micro-virtual machine (e.g., Firecracker) technologies; containers start faster but offer relatively weaker isolation, while micro-virtual machines provide higher security but greater cold-start latency.
Timeline (last 90 days)
MicroVMs (such as Firecracker, open-sourced by AWS) run an independent lightweight Linux kernel for each instance, providing hardware-level isolation.
Official Firecracker data shows its cold start time can be as low as 125 milliseconds, with a memory overhead of approximately 5 MB per virtual machine.
AWS's Firecracker and Google's crosvm are representative examples of the microVM approach.
Firecracker is a lightweight virtual machine monitor (VMM) open-sourced by AWS, built on Linux's KVM technology, and typically takes less than 125 milliseconds to start a microVM
The agent's Linux machine runs on a Firecracker virtual machine, which facilitates snapshotting, shutdown, and restart
Firecracker comes from AWS and is a micro virtual machine monitor built for Lambda and Fargate that achieves hardware-level isolation via KVM, with startup times compressible to under 125 milliseconds.
The common trend among gVisor, Firecracker, and Kata Containers is the fusion of VM-level security boundaries with container-level lightweight experience.
Firecracker microVMs are used by AWS Lambda and Fly.io.

VM-level isolation (such as Firecracker microVM) provides the strongest isolation guarantees but introduces higher startup and communication overhead.
