Top Linux Server Vendors

Filed under
Server

This article offers a 2019 update on several of the world’s top Linux server vendors, a very important but often mysterious section of the IT world that many people know little or nothing about. This is because Linux and its various flavors, called “distros” (for distributions), are underlying operating systems that run applications on servers and PCs and aren’t adjusted or changed by users as a matter of routine.

For public internet servers, Linux is dominant, powering about twice the number of hosts as Windows Server, which is trailed by many smaller players, including traditional mainframe OSes. The supercomputer field is completely dominated by Linux, with 100% of the TOP500 now running on various versions.

Internet-based servers' market share can be measured with statistical surveys of publicly accessible servers, such as web servers, mail servers or DNS servers on the Internet: the operating systems powering such servers are found by inspecting raw response messages. This method gives insight only into market share of operating systems that are publicly accessible on the Internet.

The Linux OS started out as being exclusive to regular x86 desktop PCs, but it has since found its way into everything from Android phones to Google Chromebooks to those powerful super-servers mentioned above. IT decision-makers in the market for Linux servers should know that the very best Linux distros are tailored to specific types of users. Ubuntu, for instance, is very easy to use, because it’s designed for newbies. On the other hand, Red Hat Enterprise Linux, openSUSE, CentOS and others designed for the data center require a lot more expertise.

Raspberry Pi 4: Chronicling the Desktop Experience – Week 1

This is a weekly blog about the Raspberry Pi 4 (“RPI4”), the latest product in the popular Raspberry Pi range of computers. The purpose of the blog is two-fold. Primarily, it’s to share my experiences using the RPI4 purely as a desktop replacement machine, to see what works well, and what doesn’t. It’s also to act as an aide-mémoire for myself. Along the way, I’ll be exploring what I’m looking for from a desktop machine. Smooth running multimedia, office based software, email, networking, and productivity apps are all high on my list of priorities. Rest assured, even though I am a huge advocate of the Pi range of computers, I’ll be brutally honest in my critique of RPI4. For example, the RPI4 is marketed as an energy efficient computer. In a way that’s very true. The Pi consumes a mere 2.8 watts when idle and about 5w when maxing out all 4 cores. But the firmware doesn’t automatically switch off the monitors’ backlight. Instead, it only blanks the screen. While there are plans to fix this issue (part fix with a working vcgencmd), it’s a startling omission. With inadequate power management of the monitors, it’s hard to consider the Pi 4 as an energy efficient desktop solution. Read more
