CentOS Linux
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.

For running Oracle databases, Solaris can't be beat. Leveraging Zones allows for virtualization out of the box. In addition, using zones with clustering can make migrating from Solaris 10 to 11 very easy. Finally, in an enterprise environment that requires 24/7 up-time and meeting SLA's, Solaris is a viable and robust choice.

Cons
CentOS Linux
- To maintain maximum stability, software packages may not be the latest and greatest versions but you can easily compile their source code yourself if a packaged version is missing certain functionality.
- Sometimes, the major version releases of CentOS may be delayed in delivery due to the project's infrastructure limitations. RHEL sets the cadence and others like CentOS and Oracle Enterprise Linux follow soon after.
- As it's meant for server installations, personal computer and laptop peripherals that sport the latest technologies might not be supported right away.

- It seems that Solaris is becoming an afterthought at Oracle.
- Oracle should be more vocal in their commitment to Solaris

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.

The support teams are well trained and responsive. Patches are rolled out regularly and are easy to deploy and backout.

Stress testing and timing is key. You need test systems that mirror the live environments. User testing must be reflected in peak loads.

Alternatives Considered
CentOS Linux
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.

We also use Linux in our shop. Linux is capable, and a very good OS. Solaris was chosen because we can afford it. Again Linux is capable, but Linux is a disruptive technology i.e. it is a "good enough" Unix.

CentOS Linux
- Since CentOS is free, our developers and engineers can use it without regard for dipping into project budgets.
- We can spin up a CentOS VM, use it and then destroy it without having to worry about licensing headaches.
- CentOS can run on just about any hardware platform: server, laptop, old hardware, etc. so that makes it less expensive in that we don't have to buy specialized hardware for it.

- It just runs like a top, this mean TCO is low
- We've not had issues with Solaris running on Sparc.
- Reliability is above reproach.
