Illumos

Illumos is available for free from their source repository and is the home of many technologies including ZFS, DTrace, Zones, CTF, FMA, and many more. The developers pride themselves on having a stable, highly observable, and technologically different system- its engineering heritage, tracing its roots back through Sun Microsystems to the original releases of UNIX and BSD.

There are lots of companies out there who use illumos. Lots of communities and businesses base their products and services on illumos. In addition to offering the core for projects and products, components of illumos have been ported to other operating systems.

  • FreeBSD – Incorporates ZFS, DTrace, MDB.
  • Apple – Incorporates DTrace.
  • Joyent – Public and on-prem cloud, object storage.
  • Lucera – Financial infrastructure services.
  • Delphix – Database virtualization.
