Every personal computer or server is run by an Operating System - the low-level program which interacts with the computer hardware, including peripherals such as a mouse and a printer, along with any apps that are currently installed 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 Operating System. On a server, each and every application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard Internet site scripts and server-side software like a media server. When a virtual server is generated on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so that you will be able to set up a different software environment on a single machine.
Multiple OS in VPS Servers
Our VPS server packages come with three Linux releases that you can select from for the Operating System of your new hosting server - Debian, Ubuntu and CentOS. Apart from being 100 % free, the OSs are very stable and protected and the main reason to offer the three of them is to ensure that you can run every app that you'd like, as different pieces of software could have different requirements for the environment they work on. Each of the three OSs is backed by a large community of web developers who have developed thousands of software packages that you can set up and use on your VPS. Based on the Operating System which you select, you will also be able to choose between three different Control Panels to control your hosting content. Of course, should you decide that you need another OS, we could always re-install the server with it. As an additional upgrade, we also provide weekly updates of the Operating System for maximum stability and security.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they're absolutely free so they will not increase the cost of your new hosting server, but also because they are outstandingly secure and stable. Each of them is supported by a vast community of web developers, so you'll be able to choose from many hundreds of software packages that you may install on your server if the app that you intend to employ has certain requirements. The Operating System will also determine what hosting Control Panel you can use as the Control Panels that we offer run on specific OSs only and since we would like to give you as much adaptability as possible, we offer several OSs and multiple Control Panels. If you choose a server with a given Operating System, we could change it upon request in case it turns out that you will need alternative one. We can also keep the OS updated on a weekly basis as a part of our optional Managed Services upgrade.
