What are virtual servers

Virtual server definition

What is a virtual server?

The term “virtual server” is used to denote a virtual machine (VM for short) that is created by special software on a hardware server and that behaves like a physical server even though it is not. The virtual server also provides resources such as CPU, interfaces, hard disks or memory. The virtual server is assigned to the real hardware on a physical machine. Multiple virtual servers can be installed on a physical server.

Due to their special properties, virtual servers are often used to test other operating systems and new software or to examine unknown files for malware in a secure environment (see also: sandboxing software). In addition, virtual servers save costs for maintenance, cooling and electricity, which is why they are particularly interesting for companies with large data centers or large resource requirements.

How does a virtual server work?

The basic principle behind this is to use the existing resources of the physical server in combination with those of the virtual server. To put it simply, a virtual server is a computer file that behaves like a "real" computer. The virtual machine offers the same functions and programs as a physical server. The particular advantage of a virtual server is that it acts separately from the rest of the system and the system itself is thus protected from manipulation.
