Excerpt

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.

Notes

• illumos is basically a kernel environment (similar to GNU) forked from OpenSolaris, which was made closed-source again when Oracle purchased Sun Microsystems.
