Leveraging Unikernels and Kubernetes to (Transparently)...
summary
Unikraft builds specialized unikernels that run unmodified apps with dramatically smaller footprints and faster starts: 7–14 ms cold boot and 1.2–1.9 MB images for nginx versus ~30 MB on Linux, reported throughput 50–100% higher in wrk tests, and a demonstration of creating 500 instances in about one second. Platform runs on KVM with a modified Firecracker control plane, exposes a REST API plus craft CLI, and adds Dockerfile, Terraform and Kubernetes (via Crossplane) deployment support; a 64-core node approaches ~100k VMs.
