CentOS 4 Offers Strong RHEL Alternative
Clone-ing Around?By any number of different measures, Red Hat Enterprise Linux (RHEL) currently is the established leader in the North American enterprise Linux space. Unlike its cousin Fedora (which is free) or its Red Hat Linux ancestors, RHEL can sometimes have an unpalatable cost associated with it (check out this graph on current server subscription costs). Not everyone needs the excellent support offered by Red Hat for RHEL and not everyone can afford to upgrade their systems three times a years with Fedora. What's a penniless admin to do? Send in the clones.
Thanks to Red Hat's commitment to the principles of open source as well as its open source licensed software utilization, clones of RHEL are available. The clones are not deformed knockoffs of RHEL's splendor rather they are shadows of RHEL that offer most of the same packages as RHEL (without Red Hat logos and trademarks) and in at least one case also promise errata updates at a near Red Hat pace (see Figure 1).
