An Operating System is the low-level software which manages a computer. It controls how your hardware functions, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between apps, and the prioritization of apps if multiple ones run simultaneously. Every program which is installed on a desktop or a notebook functions by sending requests to the OS for various services using an application program interface (API). The communication with the OS is possible using a Graphical User Interface (GUI) or a command line. In the hosting world, the Operating System is what commands a web server along with all the software installed on it, which includes not only website scripts, but also every other application for example a VOIP or a game server. In case there are virtual machines created, they employ a guest OS that is run on the server host OS.
Multiple OS in VPS Servers
If you choose to buy one of our VPS server packages, you'll be able to select one of the three Linux releases which we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most widespread and most stable server OSs on the market and we offer them so that you have a choice for the software environment of your machine if you want to install some application with precise requirements regarding the packages that should be present on the server. We also offer three web hosting Control Panels and which one of them you can use will depend on the OS that you've picked. We leave the option to replace the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. In addition, we can keep the OS up-to-date on a weekly basis by installing any security updates that may be available.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they're free so they will not increase the cost of your new web hosting server, but also because they are extremely secure and stable. Each of them is supported by a vast community of developers, so you'll be able to choose from countless software packages that you could install on your server if the application that you want to employ has certain requirements. The Operating System will also determine what hosting Control Panel you can use because the Control Panels that we offer run on particular OSs only and because we want to provide you with as much freedom as possible, we offer a couple of OSs and multiple Control Panels. If you get a server with a certain OS, we will change it upon request if it turns out that you'll need another one. We can also keep your OS updated on a weekly basis as a part of our useful Managed Services upgrade.
