It’s Time to Debloat the Cloud with Unikraft
summary
Unikraft builds specialized unikernel images for mainstream apps and reports concrete numbers: boot in 3–9 ms (3 ms on Firecracker locally, ~8–9 ms on EC2), 4 MB runtime, ~2 MB disk for nginx, and measured throughput exceeding Linux (300k req/s on a single core for static workloads). Supports run unmodified Linux ELF binaries via an ELF loader plus syscall shim, integrates with Kubernetes via runu, and exposes Prometheus/Grafana metrics and gdb-compatible debugging.
