Each and every personal computer 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, along with any apps 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, every single app 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 independent Operating Systems, named guest OS and host OS, so you will be able to set up a different software environment on a single machine.
Multiple OS in VPS Servers
In case you select one of our VPS server plans, you'll have 3 different Operating Systems to pick from - CentOS, Debian and Ubuntu. They are all Linux distributions and we offer them instead of offering just a single OS, as the apps that you might want to run on the server may have specific requirements about the software environment. Each one of these three has certain pros with regard to the available packages that you could eventually install, but what's common between them is that they are really secure and reliable and have huge communities which support them. The internet hosting Control Panel alternatives for the VPS accounts depend on your OS choice, so as to give you more flexibility. When you order the virtual server with one OS and you need a different one later, our technical support team can easily reinstall the VPS with the new one in just a few minutes. We also offer the option to keep the Operating System on your server up-to-date weekly.
