Each personal computer or server is run by an Operating System - the low-level program that interacts with the hardware, including peripherals such as a mouse and a printer, along with any apps that are installed on your 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 application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard site scripts and server-side software such as a media server. In case a virtual server is created on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, which means that you can set up a different software environment on a single machine.
Multiple OS in VPS Hosting
In case you decide to purchase one of our virtual private server packages, you'll be able to choose one of the three Linux releases that we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. They're among the most popular and most reliable server OSs on the market and we offer them in order to give you a choice for the software environment of your machine in case that you need to install some application with specific requirements regarding the packages that have to be present on the hosting server. We also offer three internet hosting Control Panels and which one of them you could use depends on the OS that you have selected. We leave the option to change the server Operating System open, so when you want to use an app 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 all of the security updates that may be available.
Multiple OS in Dedicated Web Hosting
In case you decide to purchase one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a larger choice regarding the system environment on the machine as different applications can have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select any of these OSs and enjoy a reliable and safe hosting service. Based on your decision, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected in the beginning does not meet the requirements of the software that you intend to run. We can also upgrade the OS on a regular basis to keep it as secure as possible using our Managed Services upgrade package.
