What’s Server Virtualization Technology?

The word virtualization will get bandied about a good deal in the realm of business, what does that term really mean? The word virtualization can be used to consult a variety of technologies, but it’s most generally connected with servers and server technology.

In the basic form, virtualization means disconnecting, or decoupling, the program utilized on that server in the hardware itself. For servers, this means that exactly the same hardware may be used to host a variety of servers, whatever the kind of software each is running.

This means that exactly the same physical bit of hardware may be used to host a web server running Home windows, another running Linux, another running OS/2 and so forth. Because the software is not determined by the hardware platform, a variety of software environmenets can share exactly the same physical box.

So with virtual server technology, you might have just one blade system running three separate Home windows servers, two different Linux systems and so forth. As these server environments are virtualized, they are able to all run on a single blade server.

This method helps companies reduce hardware, because the physical hardware is frequently probably the most costly a part of managing a web or application server. Rather of every server running by itself dedicated hardware, a number of different servers can share exactly the same atmosphere, allowing companies to chop costs and lower the complexness of managing their personal computers. Less servers means less requirement for pricey support and maintenance, supplying another financial savings for money strapped companies.

Virtual Machines

The word virtual machine is frequently used along with virtual server technology. Essentially, the virtual machine may be the server atmosphere that’s running on the particular bit of hardware. So each Home windows and Linux server running with that blade product is another virtual machine.

The virtualization process functions by putting a thin layer over the surface of the physical server. That thin layer can be used to partition the sever into distinct areas, with every area dedicated one virtual machine. The computing sources around the server are shared of all individuals virtual machines, allowing them to benefit from the ability available without requiring to dedicate the whole bit of hardware one software process.

Separate Entities

An advantage of virtual server technologies are that every vitual machine is its very own separate entity. This means that an issue with a credit card applicatoin or software program on a single virtual machine may have no effect on the rest of the virtual machines, despite the fact that all individuals other servers are running on a single bit of hardware. That strict separation of sources enables companies to operate multiple servers on a single hardware, without fear that an issue with one system brings the whole company to the knees.
