There seems to be a lot of odd nostalgia for Solaris in the comments here and on twitter. I think that's missing the point of the article. Yes, Oracle Solaris is dead. But illumos is better, open source, alive and here to stay.

You can use illumos today, right now, and have your ZFS, mdb, DTrace and zones. It really is open source and we're a community using and improving it. For 7 years now already.

As illumos is only the basic building block of the operating system (but unlike linux includes kernel + basic userland) one usually runs one of the distributions:

- SmartOS, developed by Joyent as a cloud hypervisor. Supports zones, KVM and lx-branded linux containers. [1]

- OmniOS CE, a minimal distribution targeted for bare metal server installations [2]

- OpenIndiana, similar to the traditional opensolaris. If you care about GUI this is probably the one. [3]

- Tribblix, modern components with retro style [4]

Sure, the user base is smaller than Linux. But that is also true for FreeBSD which is used by Netflix and Whatsapp. Running a different OS than most other people can give your company an advantage and I know that ZFS and zones have done that for mine.

Things make a lot more sense now. For having been interested tangentially in OpenSolaris (I still have its "bible" as a monitor stand) I never knew Illumos was the kernel, and other OSes based on it. I assumed all the different Solaris spinoffs were complete forks, and thus assumed they were all dead or dying.

I will say the wikis are not inspiring; many on Illumos, OpenIndiana and SmartOS have pages last edited multiple years ago. For Illumos, I think your info above is more useful than the alphabetical listing of distros on the wiki. I think the marketing on OI's site could better tell the "why use me over Fedora/Ubuntu/BSD?" story, and SmartOS could spend less time selling its public cloud service, and more time telling me how to create a private cloud. Its docs are not super discoverable.

All just observations; take them for what they're worth. I do think it's neat that Solaris has lived on, and it makes me want to throw up a lab server to poke around a few hours. Thanks for your work and the comment.

[snw]

Oh yes, the wikis definitly do need some love. Documentation is beeing worked on as far as I know.

A lot more of activity is going on in irc on freenode, so if you start playing with your lab server or are just interested in general you might want to drop by in #illumos or #smartos.

How does running a different OS than most people can give a company an advantage? Can you elaborate this?

[snw]

In my case illumos provided two things:

- zones allowed for a much higher deployment density and better utilisation of our hardware than other virtualization technology would have.

- zfs snapshots. We've integrated those into our product and when a customer messes up they now have button to instantly restore to a known good state.

Doing both of these things would have been a lot harder on another os.

[mysterydip]

A different OS can solve some of the pain points of the mainstream options. Depending on your business, the features a different OS brings could have a large impact on performance or stability.

Potential areas for improvement could be anything from filesystem to process concurrency to virtualization.

[fulminatorz68]

I'd see only the pain of migrating applications and learning new administration tools. Solaris was dead long before oracle killed it -- to me.

[feld]

"migrating applications" -- you'd be shocked at how unix software tends to run on... unix OSes with few to no modifications.

Things like:

  * Java
  * PHP
  * Perl
  * Python
  * Ruby
  * Apache
  * Nginx
  * Varnish
  * MySqL
  * Postgres
  * Node.js
  * etc

all run just fine on a Solaris-clone. Unless your app is using very specific kernel features it will probably work fine.

[DeathRabbit]

The comment up above in the chain was wondering whether running Solaris (or derivatives) offered any advantage. While I'm sure the packages you listed _run_ fine, how difficult would it be to find support for each when running on Solaris? You can run those softwares on Solaris, but is Solaris on the "supported platforms" list?

Not debating here, BTW; I enjoyed my time with Solaris and then its offshoots.

Edit: The thinking here only applies to systems running in production where official support is pretty much mandated.

[feld]

What do you mean "find support" ? This is open source software. Your sysadmins are your first line of support. If they can't debug issues, work with the open source community, and write basic patches in C you have the wrong staff.

[Annatar]

They run more than just fine; usually an illumos based OS will run circles around Linux on the same hardware, and the real slap is that it won't sacrifice reliability nor correctness of operation to do that.

[mrweasel]

I think you're missing the most important application for Solaris users: Oracle (the database).

The people who is going to suffer the most from Oracle killing of Solaris are largely its own database customers. I honestly doubt many Solaris customers are running an open source stack on top of it. It's the closed source applications that will be trouble some.

[tw04]

Oracle wants their customers on their exadata appliances which run Linux, not Solaris. They've been pushing customers that direction for years.

[fulminatorz68]

No, I wouldn't (having developed since 1995) but I will state that having dealt with multi-platform builds and development for bsd and linux + darwin (until recent iterations of macos) that solaris is a pitfa, just as much as macos, and one is enough.

[sethrin]

Ugh. Unix is absolutely the worst development target. It's clunky, ad-hoc, it uses some horrible ancient programming language and an even more horrible ancient scripting language. Like democracy, it's definitely the worst example of its type ever to have been invented.

[fulminatorz68]

I'd suggest your experience|expertise is lacking. My first couple of months were bad but then I learned to appreciate the expressiveness and facility of even a bad shell language and the open horizon of how things were done. This comment seems to be classic troll or sour grapes.

[feld]

If there was something better than Unix it would be taking over the world by storm.

[rhinoceraptor]

You can run docker containers on hardware instead of on virtual machines.

[Annatar]

...And unlike on Linux, it treats the entire datacenter as one giant machine.

[Annatar]

You don't have to get up at two o' clock in the morning to run fsck on a filesystem based on 30 year old concepts, for example. Or when you reboot the system, you don't have to wait 18 hours for fsck to complete because it's been more than 180 days since the last filesystem check. And I've many more examples, if you're truly interested.

[whyever]

I can think of the following reasons:

1. It is less profitable to develop exploits targeting a minor OS.

2. Minor OS may have some specific features that the major OS don't.

[reaperducer]

Ask Google.

[cryptonector]

The nostalgia I feel is for Sun, for MPK17, for the people I got to work with, and the technology. Of those things only Sun is gone, but the people scattered, and technology, though still vibrant, is still always at risk -- it depends too much on Bryan Cantrill and friends to keep it going, while the Linux crowd blissfully ignores all the good ideas and reinvents every wheel badly.

We're in a dark ages with a sliver of light. We might be in it for a while. People who have never used ZFS, SMF, DTrace, or FMA, have no idea that they are stuck in the dark.

[Annatar]

There seems to be a lot of odd nostalgia for Solaris in the comments here and on twitter.

There is nothing odd in that: contrary to the Linux party line and all the Linux hype, before illumos and SmartOS, Solaris was the most advanced operating system on the planet. As others have very accurately described and pointed out in the comments on the other reduction in force thread, this was sadly lost on the Linux generation which "grew up on the PC in their parents' basement".
