Each notebook or desktop or web server is run by an Operating System - the low-level program which interacts with the hardware, including peripherals such as a mouse or a printer, along with 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, each and every application runs within the parameters specified by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard Internet site scripts and server-side software such as a media server. When a virtual server is created on a physical one, there can be two separate Operating Systems, called guest OS and host OS, so that you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Servers
If you decide to purchase one of our VPS server packages, you shall be able to choose one of the three Linux distributions that we supply for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most widely used and most dependable server OSs out there and we offer them so that you have a choice for the software environment of your machine if you need to install some app with specific requirements with regards to the packages that have to be present on the web hosting server. We also offer three web hosting Control Panels and which one of them you could use depends on the OS that you've selected. We leave the chance to replace the server Operating System open, so when you want to use software that requires an OS different from the one that's already present, we can always re-install the VPS. In addition, we can keep the OS up-to-date on a weekly basis by installing all of the security updates that may be available.
Multiple OS in Dedicated Servers
The dedicated server packages that we offer come with three different Operating Systems to select from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license taxes, but they are also known as the most stable and secure OSs. We provide three different ones for the reason that each of them is backed by a different community. The packages which you can add on your server are different and this could matter if you need to install some piece of software with particular requirements about the hosting environment. In this light, the hosting Control Panel that you can select for the dedicated server is also determined by the Operating System that you will pick. You may choose any of the three Operating Systems throughout the order procedure, yet if needed, we can always set up the server anew with an alternative one upon your request. As an additional service that you could add to the plan at any time, we can update the OS on a regular basis in order to keep it as secure as possible.
