Is it true that most of Silicon Valley runs on CentOS?

It's mixed CentOS, Debian and Ubuntu.

Ubuntu is limited to younger folks and younger companies.

Not SV, but according to my anecdata, RHEL/CentOS is more oftenly used in enterprise deployments, while Debian (and Ubuntu) traditionally dominates Web deployments. A Debian-style Apache httpd setup with structured config files and a2ensite, a2enmod, etc. is also what mainstream shared hosting workflows are based on.

Anecdata as well, but in the years I was doing consulting in the shared hosting biz, CentOS was the clear frontrunner based on everyone I did for work. CentOS and WHM/cPanel.

And half of them had screwed up their entire setup by installing the Remi repos. Sigh.

I've been surprised how many SMBs use CentOS, I expected them to be mostly Debian too.

What kind of experience do you have to say that? (Just asking)

Netflix runs 150k servers on Ubuntu so ...

I watched a video of a recent presentation from someone at Facebook who manages their operating systems and he said they use CentOS across their fleet, so that's probably a sizeable amount.

Any reason being said or any guesses to the reasons?

The company I work for mostly uses Gentoo.

It's literally the oldest most out of date Linux distro available (even this update), so probably. CentOS recently added Python 2.7 instead of Python 2.6...

I'm pretty sure RHEL 7.0, which was released in 2014, shipped with Python 2.7 as the default.

Well what are the downsides of this? One is not limited to Python 2.7 because of the operating system, for instance.

We (Red Hat) also released an easy way to do a side by side install of newer tooling without impacting the OS. Python 3 was released on Red Hat Enterprise Linux in 2013, and we currently support Python 3.6.

Here's more on how software collections work and what is released: https://developers.redhat.com/products/softwarecollections/o...

You see old and crusty, users see a stable software API that receives security updates for decades.

IIRC it's a clone of redhat and redhat is in the business of support.

Big companies goes to red hat because they promise to support software beyond their life cycle for years. So that's that.
