Data Center Virtualization: Cloud Computing Still a Work in Progress.
The AFCOM association recently revealed the results of a survey of 436 data center sites that showed the following trends: Cyber terrorism is an increasing concern, mainframe deployment is declining, storage deployment is increasing, and “green” technologies are definitely happening.
AFCOM found that there is a shift in data centers away from mainframe computers and toward other types of servers.
That makes total sense as virtualization is the mantra of the day for those companies that are interested in optimizing their power by having several operating systems function within just one server.
Data processing and storage is done within one server as opposed to a traditional system where the network is distributed in an elaborate design comprising of several servers and workstations all attached to their own separate hardware components.
