Serverless MicroVMs for Containerized Applications
summary
Shows a working pipeline that boots OCI images as lightweight VMs: uses Firecracker (boot <150 ms, ~5 MB overhead) managed by Ignite via simple commands like ignite run and integrated into Kubernetes through Kata Containers runtime class. Demo deploys a Flask KNative service, autoscaling-to-zero works and the activator spawns a microVM on first request. Tradeoffs are clear: stronger multi‑tenant isolation and fast cold starts at the cost of limited guest OS/hardware support and unsuitability for heavy workloads.
