Firecracker strips legacy hardware emulation to get container-speed boot times with real VM-grade kernel isolation, which is exactly the tradeoff engineers building sandboxed code-execution environments for AI agents need to understand.
A technical explainer on AWS's Firecracker microVM technology, contrasting Linux container isolation (namespaces, cgroups, seccomp) with full VM isolation, and showing how microVMs strip away legacy PC hardware emulation to get near-container boot speed with VM-grade kernel isolation.
