Each PC or web server is run by an Operating System - the low-level software that communicates with the hardware, including peripherals such as a mouse and a printer, together with any applications that are installed on your system. Any program input using 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 web server, each app runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard site scripts and server-side software such as a media server. When a virtual server is set up on a physical one, there can be two separate Operating Systems, called 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 Servers
In case you pick one of our VPS server packages, you will have as many as three different Operating Systems to choose from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just a single OS, because the applications that you may wish to run on the server could have specific requirements regarding the software environment. Each one of the three has some pros regarding the available packages that you may afterwards install, but what is common between them is that they are really stable and reliable and have huge communities which support them. The web hosting Control Panel alternatives for the VPS accounts depend on your OS choice, so as to provide you with 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 a matter of minutes. We also offer you the option to keep the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server solutions - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they're completely free so they will not increase the cost of your new hosting server, but also because they are really stable and secure. Each of them is supported by a big community of web developers, so you'll be given the option to choose from a large number software packages that you may install on your server if the app that you would like to work with has certain requirements. The Operating System will also determine what internet hosting Control Panel you can use as the Control Panels that we offer run on specific OSs only and because we want to provide you with as much flexibility as possible, we offer a couple of OSs and multiple Control Panels. If you choose a server with a certain OS, we can change it upon request if it turns out that you need alternative one. We could also keep the OS updated weekly as a part of the additional Managed Services upgrade.
