About illumos
illumos is a Unix operating system which provides next-generation features for downstream distributions, including advanced system debugging, next generation filesystem, networking, and virtualization options. illumos is developed by both volunteers and companies building products on top of the software. illumos is an excellent base for both traditional and cloud-native deployments. The OmniOS and OpenIndiana distributions are a good place for new users to get started. You can install in a virtual machine or on bare metal. You need an illumos-based operating system to build illumos. Cross-compilation is not supported. illumos is freely available from our source repository. illumos is the home of many technologies including ZFS, DTrace, Zones, ctf, FMA, and more. We pride ourselves on having a stable, highly observable, and technologically different system. illumos has a proud engineering heritage, tracing it roots back through Sun Microsystems to the original releases of UNIX and BSD.
