Every PC 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, as well as any applications that are present 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 OS. On a server, any application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This goes for both standard site scripts and server-side software such as a media server. If a virtual server is generated on a physical one, there can be two separate Operating Systems, named guest OS and host OS, which means that you'll be able to set up a different software environment on the very same machine.
Multiple OS in VPS Hosting
If you choose one of our virtual private server plans, you will have as many as 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them rather than offering just a single OS, because the apps that you might choose to run on the server may have specific requirements regarding the software environment. Each one of the three has certain advantages in terms of the available plans that you can afterwards install, but what's common between them is the fact that they're really stable and dependable and have large communities which support them. The hosting Control Panel options for the VPS accounts depend on your OS choice, so as to give you more flexibility. If you order the virtual server with one OS and you need a different one later, our tech support team can easily reinstall the VPS with the new one in just a few minutes. We also offer the option to maintain the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Web Hosting
The dedicated server solutions that we offer come with as many as three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they are also considered to be among the most stable and risk-free OSs. We supply three different ones since each one of them is backed by a separate community. The packages that you could add on your web server are different and this may matter if you want to install some piece of software with particular requirements for the hosting environment. In this light, the internet hosting Control Panel that you can select for the dedicated server is also determined by the OS that you'll pick. You can select any of the three Operating Systems throughout the order procedure, but if necessary, we can always install the server once again with a different one upon your request. As an additional service that you may add to the package any time, we can update your OS on a regular basis in order to keep it as secure as possible.
