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.

Red Hat
RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.

  • In most of my scenarios—easy and quick deployment.
  • Huge KB community that helps to build and support different services on CentOS.
  • Versions lifecycle.

  • RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
  • Red Hat distribution integration is seamless as it is integrated into the kernel.
  • OpenStack support enables more customized VM templates and network configuration control.

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.

Red Hat
  • 1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
  • 2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
  • 3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
  • 4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
  • 5- Engineering team has to be more reactive when new feature is requested.

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.

RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!

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.

  • RHEV has provided a positive ROI as our customers are not experiencing as many outages during maintenances.
  • We have not experienced any catastrophic failures as a result of vsphere losing connection to the ntp.
  • There has been a level of stability in our environment that was not previously experienced with our previous vendor.
