FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
I have been a CentOS user for over 10 years and remain loyal to the core OS. When it comes to stability and speed, there's no other OS I'd recommend over it. I base this recommendation on my personal experience, as I have multiple development and production servers running the CentOS software today. It's running on newer and older hardware with ease, and the price is right!
FreeBSD is the closest to a UNIX style operating system. This has been extensively used by vendors in the field of routing, switch and security as their base operating system. This speaks for itself being a reliable, scalable and secure operating system.
Some packages can be quite old compared with other distributions
Breaking changes appear often when packages are obsoleted usually with no supported transition path (this is a general *NIX problem, but it's more accentuated in CentOS)
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.
Ubuntu Linux is another candidate that we've evaluated. It stacks up well against CentOS Linux, however it does have some quirks we need to deal with such as package management and stability. For the most part, the server version of Ubuntu is stable, but we stick with CentOS Linux because it seems to have a slight edge over Ubuntu in that realm as well. I have colleagues at other firms that are wholesale Ubuntu server infrastructure, and they are very happy with it and Ubuntu is favorable there. With the changes that have occurred or may still yet occur at CentOS Linux, we may go down the path towards Ubuntu. But for now, CentOS Linux is where we are parked and will remain for the foreseeable future.
FreeBSD was the only operating system out of many I tried to install easily on older hardware and to run in a very performant way. For example, I had a lot of trouble trying to get Ubuntu to install on older hardware and when it did, it was too slow to use. FreeBSD installed quite easily and even after installing a desktop such as XFCE - it still run surprisingly fast. I was very impressed with it's performance, which it seems is a goal of the FreeBSD project.
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.
