Commercial and community supported Linux distributions

Commercial versions of Linux have support of a company. This is what many companies want. Example of commercially supported Linux distributions are RedHat and Ubuntu.

With RedHat it is possible to get a release of Linux that will be supported for a few years, such a release has software which is well tested. At the same time it is also possible to get a release of RedHat Linux that is supported for much shorter period of time, but it has newer software.

It is also possible to get unsupported and free versions of Linux, if a company trusts packages, or has expertise in-house to support these, or can deal with issues until these are resolved by maintainers of that specific distribution.

Example of free distribution of Linux are Debian and CentOS. Debian looks like Ubuntu, and CentOS looks like RedHat Linux.
