Each and every PC or server is run by an Operating System - the low-level software which communicates with the hardware equipment, including peripheral devices such as a mouse and a printer, and 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 Operating System. On a web server, each app runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard site scripts and server-side software like 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, which means that you'll be able to set up a different software environment on the same machine.
Multiple OS in VPS Servers
If you pick one of our VPS server plans, you'll have 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them rather than offering just one OS, because the applications that you might choose to run on the server may have specific requirements regarding the software environment. Each of the three has some advantages regarding the available packages that you may eventually install, but what is common between them is that they're really secure and reliable and have large communities that support them. The hosting Control Panel options for the VPS accounts depend on your Operating System choice, in order to provide you with more flexibility. In case 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 couple of minutes. We also offer you the option to maintain the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Servers
The dedicated server solutions that we offer come with three different Operating Systems to pick from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also regarded as the most reliable and secure OSs. We offer three different ones because each of them is backed by a different community. The packages which you can add on your hosting server are different and this may matter in case you want to install some piece of software with specific requirements regarding the hosting environment. In this light, the internet hosting Control Panel which you can select for the dedicated server also depends on the OS that you will choose. You can choose any of the three Operating Systems throughout the order procedure, yet if needed, we can always set up the server once again with an alternative one upon your request. As an optional service that you may add to the package any time, we can update the OS on a regular basis so as to keep it as risk-free as possible.
