What distribution is most used in production environment
I've come across Red Hat allot lately and am wondering if I need to get studying. I'm an avid Ubuntu server user but don't want to get stuck only knowing one distro.
What is the way to go if i want to know as much as I can for use in real world situations.
It really depends. I work for a large company and we use Ubuntu, Oracle, RedHat, and SLES. We were moving from Oracle to Ubuntu but now we are going back to RedHat.
Currently we deploy like this:
Ubuntu: PostgreSQL, web servers, some engineering workstations, and big data
Oracle & RedHat: web servers, security applications, and network systems
So just having a fundamental understanding of Linux and you will be fine
SUSE: SAP and HR software
Mostly cost. We used to run a lot of Oracle databases and they have become extremely expensive to keep running. So we are migrating to PostgreSQL. The servers were getting migrated to CentOS but now that RedHat fucked that distro we are going back to RedHat. Part of that deal is switching from chef to Ansible. So to save costs we are consolidating to a single vendor.
Oracle DB are sucking a lot of money, but they fork RHEL for free...(well it is open for everyone), they offer more expensive contract on top of Oracle DB, what a free estate.. haha... Nice work ORACLE... :/
