illumos is an open source operating system project that is a descendant of OpenSolaris. It was created as a community-led continuation of OpenSolaris development after Oracle discontinued updates. The illumos project aims to maintain 100% API/ABI compatibility with Solaris while allowing for independent innovation. It has a growing community of developers and is used as the basis for distributions like OpenIndiana.

1. illumos tm - update Garrett D'Amore Tech Lead, illumos

2. What's In A Name illumos = illum + OS = “Light + OS” Light as in coming from the Sun

3. OS as in Operating System

4. Note: “illumos” is all lower case

5. “illumos” is a trademarked name

6. What Is “illumos”? The natural descendent of OpenSolaris Building upon 20 years of Solaris legacy

7. SVR4.2 and POSIX/SUS heritage Community project

8. Centered around the core part of the operating system (“ON”)

9. Original Rationale Critical components of OpenSolaris are not open source. Internationalized bits (much of libc)

10. NFS lock manager

11. Parts of crypto

12. Various drivers

13. Challenges to Downstream Downstream consumers can't self support without open source Nexenta, Greenbytes, Belenix, Milax, EON, Joyent, etc. Concern about discontinuing source updates Seems prophetic in retrospect

14. New Motivations OpenSolaris is dead

15. Oracle open source commitment

16. Oracle priorities

17. Uncertainty about Solaris future

18. New opportunities

19. New innovation

20. Why Solaris/OpenSolaris? World class tech ZFS, DTrace, Crossbow, Zones, etc.

21. Bulk of code is open

22. Outstanding code quality World class engineers Inventors of ZFS, slab allocator, and DTrace

23. Awesome community of enthusiasts Vibrant ecosystem

24. The illumos Project Derivative of OS/Net This is the foundation of Oracle Solaris

25. Fork starting with last code drop from Oracle (b147+)

26. 100% ABI compatible with Solaris ON Make all code open source Not quite there yet, but making progress!

27. Innovation and illumos We intend to the be a center, perhaps the center of innovation for Solaris tech We no longer have to worry about merging!

28. Already have some innovations integrated

29. Signficant innovativations in the pipe illumos as the “upstream” for Solaris?

30. illumos Components Illumos-gate is just ON Focused on “Core Foundation Blocks”

31. Flagship project for illumos Other projects hosted Umbrella organization

32. OpenIndiana distribution

33. Other distros?

34. Other consolidations?
