Data center virtualization is the process of moving information storage from physical to virtual servers in different locations, reducing costs and increasing data availability. It combines high-speed data transfer and server virtualization, allowing data to exist in multiple locations and reducing the need for physical servers. It also costs less than traditional data storage and reduces hardware and personnel costs.
Data center virtualization is a method of moving information storage from physical to virtual servers, often in a different location. In the past, large companies maintained physical servers on site that held huge amounts of business information. These servers were expensive, both to purchase and to maintain. With data center virtualization, it has become possible to separate both hardware and location from data. This reduces costs and increases data availability.
Data center virtualization actually comes from the combination of two different technologies; high-speed data transfer and server virtualization. Without both of these components, data center virtualization becomes extremely impractical. While high-speed data transfer has been around for a long time, server virtualization didn’t become practical until the early 21st century.
High-speed data transfer allows separation of information from location. With traditional data centers, information was stored on site, so it was always accessible to workers. As Internet speeds increased, it became possible to retrieve information from distant locations almost as quickly as a home server. With this kind of speed at your fingertips, you can maintain your data center almost anywhere there’s a good Internet connection.
Server virtualization is all about using software to do the work of hardware. A single computer running a single server will always have periods where it is idle or doing very little. By running server virtualization software on that single machine, it can act as if it were two or more completely independent servers. Now, when one server is down, the others can still function. This reduces inefficiency and reduces the number of machines needed to perform tasks.
There are many business applications for data center virtualization. Data can exist in multiple locations at the same time. When changes are made to a database, the change can migrate through a series of virtual servers until all have the new data. Instead of databases being offline when the server needs a fix, the business can simply log into an offsite location. If one of the offsite locations becomes inaccessible, other servers with the same information are available.
Data center virtualization also costs less than traditional data storage. On the local front, the company has fewer servers to maintain, reducing hardware and personnel costs. The offsite location has a number of virtual servers. These machines are doing the work of many physical servers, which also reduces their cost.
