An Operating System is the low-level software which manages a computer. It controls the way your hardware functions, the communication with peripheral devices such as a monitor, a printer or a keyboard, the allocation of memory between your applications, plus the prioritization of apps if multiple ones run simultaneously. Every program that's installed on a desktop or a laptop operates by sending requests to the OS for various services via an application program interface (API). The interaction with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the hosting field, the Operating System is what controls a hosting server together with all the software installed on it, which includes not only website scripts, but also every other application for example a VOIP or a game server. In case there are virtual machines created, they employ a guest OS that is run on the server host OS.
Multiple OS in VPS Servers
If you decide to acquire one of our VPS server plans, you'll be able to select one of the three Linux distributions which we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most popular and most dependable server OSs available and we offer them in order to give you a choice for the software environment of your machine in case that you want to install some application with particular requirements with regards to the packages that need to be present on the server. We also offer three internet hosting Control Panels and which one of them you could use depends on the OS that you've selected. We leave the possibility to replace 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. In addition, we can keep the OS up-to-date weekly by installing any security updates that may be available.
Multiple OS in Dedicated Servers
The dedicated servers we offer come with as many as three different Operating Systems since we want to give you more flexible plans which will let you install and run any type of web software irrespective of its system requirements. The options are CentOS, Debian and Ubuntu and these 3 OSs are some of the most reliable and secure ones, not mentioning that they don't have any license charges. All three have a large number of developers that have created numerous software packages that you could install and use on your hosting server. We also offer three hosting Control Panels and which one you can use will depend on the Operating System that you choose when you sign up. If you need another OS subsequently, it will not be a problem since we can always reinstall your server. With our Managed Services package we can also keep your OS secure by upgrading it on a weekly basis with any patches that are released for it.
