Why virtualize?
-
- Virtualization enables the simultaneous running of several separate operating systems (even of different types – Windows, Linux, MacOSX, etc.) on one computer (usually a server). In this way, both hardware and electrical energy are saved, since only one machine is running.
-
- Thanks to virtualization, it is possible to easily test, for example, program updates, program behavior or settings in different versions of operating programs. If something goes wrong, you simply revert to the original state of the system.
-
- From the above it follows that virtualization is great for backup. And even more backups during the day. So-called Disaster recovery is handled very well with it.
- In case of a server failure, normal recovery of the virtual server can be a matter of units to tens of minutes. In the case of a non-virtualized environment, this time is usually in the order of units to tens of hours. Critical virtual machines can run in a so-called cluster, and in case of failure of an active virtual machine, a cloned backup virtual machine takes over its function and the user hardly notices the failure.
We virtualize! This saves time and system resources. We will speed up recovery after a disaster. Virtualization makes sense.
