Every single personal computer or server is run by an Operating System - the low-level software that interacts with the computer hardware, including peripherals such as a mouse and a printer, as well as any applications that are present on the system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a server, any app runs within the parameters established by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard Internet site scripts and server-side software like a media server. In case a virtual server is set up on a physical one, there can be two separate Operating Systems, called guest OS and host OS, which means that you can set up a different software environment on a single machine.
Multiple OS in VPS Servers
In case you decide to purchase one of our VPS server plans, you shall be able to select one of the three Linux releases that we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most well-known and most dependable server OSs on the market and we offer them so that you have a choice for the software environment of your machine in case that you would like to install some app with specific requirements regarding the packages that have to be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you may use depends on the OS that you've chosen. We leave the possibility to change the server Operating System open, so when you want to use an application that requires an OS different from the one you have, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing any security updates which may be released.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server plans - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they're 100 % free so they won't increase the price of your new hosting server, but also because they are extremely secure and stable. Each of them is backed up by a large community of developers, so you'll be given the option to choose from a myriad of software packages that you may install on your server if the application that you would like to work with has certain requirements. The Operating System will also determine what web hosting Control Panel you can use as the Control Panels that we offer run on specific OSs only and since we want to give you as much versatility as possible, we offer multiple OSs and multiple Control Panels. If you get a server with a certain OS, we will change it upon request if it turns out that you will need alternative one. We can also keep your OS updated on a weekly basis as part of the optional Managed Services upgrade.
