Operating Systems
So, you're ready to delve into what your Linux VPS will run?
The Linux server platform is used worldwide by enthusiasts, technically-savvy entrepreneurs and small to large (very, large) companies. It has, without doubt, become one of the most powerful operating systems for VPS. Furthermore, it is a cost-effective replacement to Windows Server (or even Desktop) with fantastic desktop editing, email clients et al.
The most remarkable feature of Linux is that the Linux Operating System is entirely open-source. Due to this, it can feature and integrate with other open-source programs; like PHP-based applications, Apache Web server and so on. Without going into too much detail this is all well and good but what do its users say? Well, the Linux control panel console is largely preferred for editing configurations etc - so it's free and it's the preferred toolset.
There are many, many Linux distributions (commonly known as "distros") for users or for use on a server. So, if you are looking to deploy the Linux VPS for your workload, you can opt Linux “distros” or “distributions”, which this category will help you with.
