Why Linux might be good for your data centre

It's a topic that often generates fierce debate among IT professionals, with die-hard advocates on either side: should you stock your data centre with Windows servers, or with Linux servers? While both approaches have their merits, there are some unquestionable advantages to opting for Linux servers.

While Windows Server may be a relatively safe, comfortable and secure option, many object to Microsoft trying to police what sysadmins can and can't do with their own servers, and see moving to Linux as a way to take back control and forge their own destiny.

It's true that Linux servers negate the risk of vendor lock-in, allowing companies to mix and match between different services and providers. However, companies that make the move to Linux could find that the tools and processes they once relied don't support Linux, leaving them out in the cold.

More affordable

The first thing that any Linux fan will tell you when asked about its benefits is that unlike Microsoft's OS, it's free to install. While this is true for desktops, it's slightly more complicated in the server space.

You can technically download and run Linux in your data centre for absolutely nothing, but businesses will need support services in case things go off the rails, and those aren't free. With that being said, however, Linux is almost always cheaper to run than Windows Server, as there are no per-seat licensing costs.

More stable

Despite numerous improvements to Windows Server over the past few years, many people still view Linux as a more stable and reliable operating system, with a lower risk of crashes and errors. Linux can also handle more simultaneous processes and don't need to be restarted as frequently, leading to less overall downtime.

This is due in large part to the fact that it's incredibly stripped-back and efficient. Because there's very little in a Linux distro that doesn't absolutely need to be there, there's less to go wrong and throw your data centre into chaos.

Light on resources

Linux has a reputation for being incredibly lightweight, and it's a well-earned one. Most Linux distros can pretty much run on a toaster, and this is just as applicable to server software as it is to desktop operating systems.

You can run a Linux server on a machine as comparatively under-powered as the Raspberry Pi, which means it's incredibly easy to get servers spun up without necessarily needing stacks of expensive hardware to do so. This isn't likely to be much of a concern for larger enterprises, but if you're a small business or startup, Linux could slash your initial IT CapEx costs.

Improved security

Another major selling-point of Linux servers (and open source software in general) is a belief that they're inherently more secure than their counterparts. The theory is that because everyone is free to examine the source code, bugs are found more quickly and patches can be pushed out by the community, without waiting for the manufacturer to roll out a fix.

While this doesn't always hold true - the Heartbleed bug is proof of that - it must be said that Linux generally has less colossal security blunders than other operating systems, and is often held to be more resilient by cyber security experts.
