Operating systems for servers

Operating systems for servers

A major decision-making criterion for selecting a suitable dedicated or virtual hosting server is the possibility to select from different operating systems. The right operating system is vital to any server. It manages major system resources such as main memory, harddisks and input and output devices, and makes them available to the application programs. This makes the operating system the most important link between the hardware components and the user’s application software.

As an Internet service-provider, Keyweb offers to users and developers a wide variety of operating systems which can also provide considerable scope at root level. In addition to the licensed Windows operating systems, namely Windows Server 2012 Standard and Windows Server 2012 R2 from Microsoft®, you can also choose the right system for you from five different low-cost Linux derivatives and one Unix derivate. Keyweb’s open-source portfolio includes the Debian, SuSE and Ubuntu operating systems, as well as Images CentOS, Fedora and FreeBSD. The KeyHelp® and Plesk administration tools are available to manage the respective server systems.

With the selected administration interface, or should you not require an admin panel, the following versions of Linux and Unix derivatives can be installed:

Debian openSUSE CentOS Ubuntu FreeBSD and Fedora
Server with Administration Plesk 8
6 and 7 14.04 only if customer specifies,
always in the current version
Server with Administration KeyHelp® 8
- - 14.04
Server without any administration software 8
13.2 6 and 7 14.04

As a further alternative, we can offer you Apple®’s Unix-based Mac OS X operating system in the variants Mac OS X Yosemite and Mac OS Yosemite Server. Mac OS X is the basic operating system for your Mac Server infrastructure. This operating system is only available in combination with the Mac Hosting products.

It is ultimately up to you which operating system best suits your requirements and makes it possible for you to implement your specific projects. We will be happy to provide any advice you may need.
