MirageOS 3.5 releases: library operating system that constructs unikernels for secure, high-performance network applications

MirageOS

MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms. Code can be developed on a traditional OS such as Linux or MacOS X, and then compiled into a fully-standalone, specialized unikernel that runs under the Xen or KVM hypervisors as well as lightweight hypervisors like FreeBSD’s BHyve, OpenBSD’s VMM. Xen and KVM power many public clouds; MirageOS unikernels are currently running on Amazon’s Elastic Compute Cloud and Google Compute Engine, and maybe others!

This lets your services run more efficiently, securely and with finer control than with a full conventional software stack.

MirageOS uses the OCaml language, with libraries that provide networking, storage and concurrency support that work under Unix during development, but become operating system drivers when being compiled for production deployment. The framework is fully event-driven, with no support for preemptive threading.
