We piloted with CentOS and RedHat, however, ultimately landed on Ubuntu as it was quickly rising in popularity and has become one of the most widely used in the world. 

Ubuntu Linux is reliable, has easy package management and is easy to upgrade from one version to the next. Windows can not offer that. Ubuntu's deployments are easy with a very reliable machine, which Windows has shown that they can't do.

We previously evaluated Centos and OpenStack.

When I started using it initially, it had better accessibility and speed. I have a low-end laptop with an AMD processor that doesn't work well with Windows. So, I chose Ubuntu Linux as it works efficiently on that device too.

I can't speak to Unbuntu versus Red Hat or other Linux solutions, however, I am aware that some people use them.

Before choosing Ubuntu Linux, I evaluated other options like CentOS. I felt Ubuntu Linux was good compared to other solutions in terms of support.

We evaluated CentOS and Red Hat.

I have evaluated other distributions of Linux, such as Red Hat.

There are those who prefer Windows for its UI features, but I am not one of them. 

When it comes to the stability of Ubuntu Linux versus that of Windows, the former, in respect of developer machines, is less energy consuming, which translates into a longer shelf life. 

We prefer both Mac and Unix. 

The main advantage of Unix is that it's free. 

Windows Unix and Ubuntu provide a free license and one need just pay for the hardware. Mac is costly. Ubuntu provides a cheaper and better option. 

However, the price criteria is not why we use Ubuntu Linux, but because it is scalable, stable and developer-friendly. 

Windows is a more user-friendly solution than Ubuntu Linux. 

Some of my colleagues use Mint, but it's a matter of preference and specific to each person. 

RHEL and SUSE Linux.

Before choosing Ubuntu Linux, I evaluated SUSE. I chose Ubuntu Linux because it has a low maintenance cost.

VMware vSAN (still have), Microsoft Windows Storage Spaces Direct/S2D (still have), Dell EMC ECS/Atmos (still have), OpenStack Swift (still have), AWS S3 (still have), Azure (still have), Datacore (did a trial), and many others.

Some others to look at and consider include Dell EMC ScaleIO, Elastifile, Hedvig, HDS HCP, NetApp StorageGrid, Nexenta, Noobaa, Rozo, Starwind, Storpool, Virtuozzo, and WekaIO, among others.

We may have evaluated other options, however, it was a long time ago. 

Many other Linux distros were selected for testing, but Debian core was very stable. However, the Debian distro itself was very annoying, missing many basic packages, and had little to no support for template deployment in VMware vCenter 5.5 to current.

I evaluated RedHat and Debian.

I also like Red Hat, CentOS and Fedora; however, upgrading to latest releases without reinstalling the complete OS seems only to be painless with Ubuntu (please correct me if I am wrong, maybe it always went well for you?).

We evaluated Google Cloud Compute and Amazon AWS.

Not really. For me, ten years ago the options were only two; stay with Windows or change to Linux.

Cisco or Juniper.

I've evaluated Red Hat and Windows 10. I'm still using Windows 10, e.g. I'm using it in parallel with Ubuntu Linux.

I have been working on many Linux Distro till now. I evaluate the new release of the main distros to find out new features.

We did not evaluate other options.
