In any role where you need raw server power, CentOS Linux is extremely well suited. It is extremely stable, and in my experience, probably the most stable of the Linux distros available. It has a very wide base of support from 3rd party sources for additional functionality that do not come already in the CentOS Linux distribution itself. It is not as appropriate for situations that are customer facing or end user facing. For those, I recommend Ubuntu Linux. But for everything server & compute related, I recommend CentOS Linux.

Cons
Open Source
  • CentOS is not a great desktop platform. Although some would disagree with that statement, I think that CentOS is better suited to life as a server.
  • Since CentOS is community-supported some software vendors will not officially support it because it isn't Red Hat.

  • Needed more CASE tools like RDi on IBM i to be developed.
  • The webSphere-related hosting procedure needs to improvised for quick turnaround or setup.
  • Just like XML-into, JSON based parser will be helpful to deal with modern data sets.

Again, written documentation is excellent, even on the older versions. The support community is the best. It is comprehensive and I would say that it global because it transcends national boundaries. Also, you find all types of people using CentOS to do all sorts of things so you are bound to find someone to talk to if there are problems.

CentOS is based on RHEL, so it really came down to the costs when making the selection between our options. RHEL offered more support and features, but nothing that we specifically needed. CentOS is fully customizable, something Windows Server was also lacking in many ways. The stability and speed was unmatched in comparison to Windows, and we were not utilizing any Windows-specific software to require us to use the Microsoft alternative. My years of experience have also made it a breeze to set up and configure new CentOS instances, leading me to stay where I'm comfortable.

IBM i is IBM's well-told and well-known system. IBM i is popular in companies in the manufacturing and supply chain business. Thanks to IBM that it kept IBM i (AS400) ever-evolving so far.

Return on Investment
Open Source
  • CentOS's support of RPM packages makes it very easy to replicate RHEL servers for development or testing in cheap / free environments
  • CentOS's minimalistic desktop environment requires additional tweaking / packages if you want to have a usable desktop environment with the niceties of other modern distributions. As a result, if developers want to use CentOS, they'll need to spend more time customizing it than other distros.
  • CentOS's easy customization from the command line lends itself well to our virtualization infrastructure where setup can be easily scripted to modify CentOS's configuration files.
