Lightning Talk: What Are MicroVMs? And Why Should I Care?
summary
Defines microVMs as lightweight virtualization with a minimal VMM that prioritizes security (smaller attack surface), speed (Firecracker claims <125 ms to start its process) and efficiency (<5 MB overhead per VM typical). Explains constraints: reduced device model, process‑per‑VM architecture and root‑volume workflows, and notes Firecracker (AWS Lambda/Fargate heritage, Linux only, no PCI passt‑through) versus Cloud Hypervisor (PCI pass‑through, vDPA, TDX/SGX, Windows/Linux guests). Gives concrete use cases: isolated build runners, per‑customer Kubernetes nodes, fast PR preview environments, and edge density gains.
