Distributed computing, falling technology prices and budget liberalization have led to the proliferation of application specialization servers. For CIOs, this will lead to a significant increase in support costs, not just the exponential growth of the number of servers, but also the spread of the distribution within the company, often away from the central technical support resources. These platforms are often not fully utilized, nor conform to enterprise standards, resulting in compliance audits and security are difficult to guarantee. It is these problems and costs that drive attention to "server consolidation," Server virtualization, and cloud computing. Server consolidation virtualization central server cluster means replacing the big ...
