An Operating System is the basic software that controls a computer system. It handles how your hardware operates, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between applications, along with the prioritization of applications if multiple ones run at once. Each and every program that's installed on a desktop or a laptop works by sending requests to the OS for various services using an application program interface (API). The interaction with the OS is possible using a Graphical User Interface (GUI) or a command line. In the web hosting field, the Operating System is what commands a web server as well as all of the software installed on it, which includes not only website scripts, but, in addition any other application for example a VOIP or a game server. When there are virtual machines created, they use a guest OS that runs on the server host OS.
Multiple OS in VPS Servers
In case you choose to purchase one of our VPS server
plans, you shall be able to choose one of the three Linux releases that we offer for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most popular and most stable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you wish to install some app with specific requirements regarding the packages that have to be present on the server. We also offer three hosting Control Panels and which one of them you can use will depend on the OS that you have selected. We leave the chance to change the server Operating System open, so if you want to use an app that requires an OS different from the one you have, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing all of the security updates that may be available.
Multiple OS in Dedicated Servers
In case you decide to purchase one of our dedicated servers
, you shall find three Operating Systems on the order page as we want to give you a larger choice regarding the system environment on your machine as different apps can have specific requirements. CentOS, Ubuntu and Debian include different modules developed by their large support communities, so you can select any of these OSs and benefit from a reliable and safe web hosting service. Based on your choice, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you have selected initially does not meet the requirements of the software that you want to run. We can also update your OS routinely in order to keep it as secure as possible through our Managed Services upgrade package.
