Unikraft: automatically build unikernels
Unikraft is a comprehensive toolchain and library operating system which builds highly specialized unikernels, software bundles that consist of a target application along with just the operating system primitives and libraries features it needs to run.
Unikraft breaks the status quo of building unikernels manually, providing an automated toolchain that builds tailored unikernels that meet your (and your application's) needs.
We haven't been paying a lot of attention to the concept of unikernels on OSNews, and I'm not sure why - possibly because they're outside of the comfort one of a lot of people, including myself.
