Virtualization of the server instance is nowadays a standard. Hardware, licensing policy of operating systems and applications, as well as technologies such as backup, monitoring or management environment are adapted to it. The view of virtualization as an advantage of portable virtual servers running on virtual hardware has become ordinary.
Technologies of virtual networks and virtual network devices, or virtual disk systems based on the internal drive, come to the foreground. Software-defined data centres (SDDC) such as vision extend virtualization to all components of infrastructure, not only the processor and memory. Virtual switches, routers, firewalls, storage arrays enable a much higher level of abstraction from specific hardware. But the most important thing is that the same virtualization platform for servers, as well as infrastructure, allows for a much higher level of automation of IT processes and is able to meet the requirement to provide IT as a service much better.
