I was looking for a server edition of Fedora to download, and just found that they don't have one. It's very strange to me. If Ubuntu has both desktop and server editions, why doesn't Fedora follow suit?
Why isn't there a server edition for Fedora like Ubuntu?
ubuntu;fedora
Fedora only has a Desktop edition.  In my experience, server distros have a longer support lifetime than desktop distros.  If you want something that has a longer support cycle, use Red Hat Enterprise Linux, or one of the RHEL clones like CentOS.  Fedora really isn't suited for a long-term support OS, because at best you'll get 13 months of support if you install a release the day it comes out (Unlike RHEL).While Fedora is really only aimed at the desktop, the OS certainly supports being installed as a server, using the DVD or network installer.  RHEL6 is based on Fedora 12 (with backports from later Fedoras and security fixes) and uses the same installation software as Fedora, so there's nothing stopping you from using Fedora as a server OS, just don't expect to get updates or security fixes past the end of its support lifetime.
