MirageOS

MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications across various cloud computing and mobile platforms. Developers can write code on a traditional OS such as Linux or macOS. They can then compile their code into a fully-standalone, specialised unikernel that runs under the Xen or KVM hypervisors and lightweight hypervisors like FreeBSD's BHyve, OpenBSD's VMM. These unikernels can deploy on public clouds, like Amazon's Elastic Compute Cloud and Google Compute Engine, or private deployments.

• Fast Start: MirageOS applications take a few milliseconds to start-up instead of the few minutes that traditional OSes take.
• Small Binaries: MirageOS binaries are self-contained: they do not need an additional OS to execute. Even then, the size of MirageOS binary is usually a few megabytes.
• Small Footprint: MirageOS applications use a few megabytes of memory, while traditional applications and their associated OS waste gigabytes for simple applications.
• Safe Logic: MirageOS applications are written in OCaml, an industrial strength programming language supporting functional, imperative and object-oriented styles.
