Each desktop or notebook or server is run by an Operating System - the low-level program which communicates with the hardware, including peripherals such as a mouse or a printer, together with any apps that are currently installed on the system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, each application runs within the parameters defined 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. If a virtual server is generated on a physical one, there can be two independent Operating Systems, called guest OS and host OS, so you will be able to set up a different software environment on a single machine.
Multiple OS in VPS Servers
In case you choose to acquire one of our VPS server plans, you will be able to choose one of the three Linux distributions that we offer for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most well-known and most reliable server OSs out there and we offer them so that you have a choice for the software environment of your machine in case that you wish to install some application with precise requirements in terms of the packages that have to be present on the hosting server. We also offer three hosting Control Panels and which one of them you'll be able to use depends on the OS that you've selected. We leave the chance to change the server Operating System open, so when you want to use an application that requires an OS different from the one you already have, we can always re-install 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
The dedicated server solutions that we offer come with three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they are also considered to be among the most dependable and safe OSs. We provide three different ones as each one of them is supported by a different community. The packages which you can add on your server are different and this may matter in case you need to install some piece of software with specific requirements regarding the hosting environment. In this light, the hosting Control Panel that you can select for the dedicated server also depends on the OS that you will select. You can select any of the three Operating Systems during the order procedure, but if necessary, we can always install the server anew with an alternative one upon your request. As an optional service that you could add to the package whenever you want, we can update your OS regularly in order to keep it as risk-free as possible.
