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
. But for everything server & compute related, I recommend CentOS Linux.

It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.
Read full review Pros First of all, CentOS is one of the most secure and stable OSes straits from the box. High performance on the average hardware. In most of my scenarios—easy and quick deployment. Huge KB community that helps to build and support different services on CentOS. Versions lifecycle. Read full review It is simple to install - there is no advanced knowledge required to begin building virtual computers It is easy to use - adding new virtual machines is simple with wizard-based deployment It enables easy portability - moving virtual machines from one host to another is straight-forward and simple It is free Read full review Cons 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. Read full review I have had issues in the past when it has come to resizing VM disk storage. The issue is entirely detailed here: https://www.virtualbox.org/ticket/9103 -- the problem was caused because of having existing snapshots (which error message output was not detailing). I haven't had to deal with the issue due to my dynamic disk sizes not being small from the start anymore (this is mostly an issue for my Windows VMs where the base disk may need significant size for the OS). It looks like, for a resize, that a merge of all snapshots has to occur first -- one user on that list details a workaround to maintain snapshots by cloning the VM. (Note: 5.2 was just released a few weeks ago, and looks like it should prevent the problem happening in the future by properly informing users that it isn't possible with snapshots). Certain scenarios, like resizing disks, required dropping into a terminal as there were no options to previously do so via the GUI. According to some recent posts, I've seen that v5.2 has added disk management stuff like that to the GUI (or will be adding it). I'm comfortable with dropping into the terminal, but in a teaching scenario or when evaluating the learnability of the tools, it complicates things. Read full review Likelihood to Renew
I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used
Read full review Usability
Easy and quick to use. Runs at sufficient speed even with 5/6 VMs running, and can handle a bridged network with ease. Easy to disassociate from the host to ensure the environment built within VB is quarantined should anything happen, meaning no risk to physical hardware. Quick to pick up. Quick to add new machines. Cloning feature very quick and comprehensive. I've never had a VM crash or freeze.

Dependency on the Host OS means it is as reliable as it is possible to be. Application errors are beyond the purview of the application.

No issues, especially with the extensions addons.

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.

Oracle have a very fast response rate and a strong user community. One can geet help from many sources if they choose to research for themselves.

We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.
Read full review Alternatives Considered
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
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.

VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition

The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.
Read full review Return on Investment 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. Read full review For personal use, there is no monetary investment, I am running 5 CentOS servers flawlessly in my home lab. Saves a ton of money in an enterprise environment by not having to purchase physical test servers. (Cost of Enterprise product is way lower vs Cost of standing up physical servers and/or cloud servers) Makes virtualization very easy and friendly for everyone for test instances.
