Is the Time Ripe for Unikernels to Become Mainstream with Unikraft?

" summary

Unikraft is a Linux Foundation unikernel project that modularizes OS primitives into libraries so developers can build tiny, specialized unikernels by selecting only needed components. It provides composable, performance-focused APIs, aims for POSIX compatibility (supporting 130+ syscalls), and integrates with tooling like Kubernetes and Prometheus; benchmarks with Nginx, SQLite and Redis show 30–50% throughput gains, ~1MB images, <10MB RAM, and millisecond boot times on a VMM.
