Linux ServerWatch writes about the slow but sure death of UNIX by the onslaught of Linux and customers moving from older proprietary UNIX systems to commercially supported open source enterprise Linux distributions. "Linux does have one killer feature that is driving the switch: lower cost. Many companies are discovering Linux to be extremely attractive from a cost perspective. Take the experience of Sabre, a travel company that replaced Solaris with Red Hat Enterprise Linux (RHEL) running on x86 machines, resulting in lowering costs 90 percent (with a three-fold speed gain to boot). These potential cost savings, which include hardware maintenance costs savings, are not to sniffed at."

RE[2]: Misleading...

Member since:

Actually for commercial use Solaris is NOT free.

"In order to use the Solaris 10 Operating System for perpetual commercial use, each system running the Solaris 10 OS must have an entitlement to do so." - Sun Solaris License Legal requirements.

Ah, but the entitlement IS free. So you're wrong :-)

If you cease paying for a subscription at Redhat you can legally continue to use the OS even commercially.

Unless RedHat has changed their license since I was a subscriber, that isn't true. They told us that unless we stripped out their copyrighted material (which at the time consisted of several specific packages) we couldn't continue to use it.

Though you will get no support (including errata) for that OS. More importantly though is the existence of CentOS which is the source from Redhat compiled. It is for all intents and purposes Redhat Enterprise Linux. Difference? Support. If you want commercial support for the OS and the applications that run on (most of them) you will want Redhat. Otherwise you have a truly free and truly open alternative which cant be said for any commercial flavour of unix AFAIK.

By contrast, you'll every major release for free from Sun and security fixes in the meantime.

So again, you might want to look closer :-)

For those that want something that is completely open source (for all the parts Sun owns) but is fully redistributable, look here:

...commercial support is coming soon too.
