An Operating System is the fundamental software which controls a PC. It controls the way your hardware operates, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between all the applications, as well as the prioritization of apps in case several run at once. Any program that is installed on a PC operates by sending requests to the OS for various services by using an application program interface (API). The interaction with the OS can be done via a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what controls a web server along with all of the software installed on it, which includes not only website scripts, but, in addition every other application for example a VOIP or a game server. In case there are virtual machines created, they employ a guest OS which runs on the server host OS.
Multiple OS in VPS Servers
If you choose to purchase one of our VPS server
plans, you shall be able to opt for one of the three Linux releases that we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most preferred and most reliable server OSs available and we offer them so that you have a choice for the software environment of your machine in case that you wish to install some application with specific requirements regarding the packages that need to be present on the hosting server. We also offer three hosting Control Panels and which one of them you'll be able to 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 software that requires an OS different from the one that's already present, we can always reinstall the VPS. In addition, we can keep the OS up-to-date on a weekly basis by installing all of the security updates which may be released.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server
plans - CentOS, Ubuntu and Debian. They're 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 server, but also because they are very secure and stable. Each of them is supported by a large community of web developers, so you'll be able to choose from a myriad of software packages that you could install on your server if the application that you intend to use has specific requirements. The Operating System will also determine what internet hosting Control Panel you can use as the Control Panels that we offer are compatible with particular OSs only and because we would like to provide you with as much flexibility as possible, we offer several OSs and multiple Control Panels. If you get a server with a given Operating System, we can change it upon request in case it turns out that you will need alternative one. We can also keep the OS updated on a weekly basis as a part of our useful Managed Services upgrade.
