Each PC or web server is run by an Operating System - the low-level program that communicates with the hardware, including peripheral devices such as a mouse and a printer, and any applications that are currently 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 app runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard Internet 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 separate Operating Systems, referred to as guest OS and host OS, so you can set up a different software environment on a single machine.
Multiple OS in VPS Web Hosting
In case you choose to acquire one of our virtual private server packages, you shall be able to opt for one of the three Linux distributions that we provide for the Operating System 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 in order to give you a choice for the software environment of your machine if you want to install some app with particular requirements in terms of the packages that should 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've chosen. We leave the option to replace the server Operating System open, so if 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 all the security updates which may be available.
Multiple OS in Dedicated Servers Hosting
The dedicated server plans that we offer come with as many as three different Operating Systems to choose from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also considered to be among the most stable and secure OSs. We provide three different ones because each of them is backed by a separate community. The packages which you can add on your web server are different and this may matter if you want to install some piece of software with specific requirements regarding the hosting environment. In this light, the web hosting Control Panel that you can select for the dedicated server also depends on the OS that you'll pick. You may choose any of the three Operating Systems during the order process, yet if needed, we can always set up the server anew with a different one upon your request. As an optional service that you could add to the plan any time, we can update the OS on a regular basis in order to keep it as secure as possible.
