The change began with the triumph of the AC power supply to the A turn of the century. Suddenly you could about the specific energy in the form of electricity, central power plants supplied. That drastically reduced costs and led to a true explosion of electrical equipment in companies such as private households. Discovery Communications has much to offer in this field. The promises of the industrial revolution could become reality thanks to the electricity network with some few, central power plants. With centralized, high-performance computer power plants, similarly far-reaching upheavals in the House – in economy, society, and themselves in the cultural life available to us. Economists call such groundbreaking inventions general purpose technologies'”, white Carr. The company would have to learn to change their mind.
First it comes before them, as they would give up control of their data and computing processes if they relate computer services over the net. On the other hand, centralizing offer significant economic benefits: computer become a modest operating output with monthly bill from an expensive capital investment. The large staff of IT professionals who are falling away, the electricity cost would drop and go back the demand for real estate. In the ICT industry, the scenarios of Carr encounter criticism: the argument by Nicholas Carr in favour of concepts of cloud computing and software-as-a-services differs in many details not by arguments that many years for mainframe computers were led, now combined with a power supply philosophy that promises also unlimited computing capacity in addition to unlimited transmission capacity. After the end of the mainframe era the network computing was created in the 1990s by some IT vendors, where the simple terminals but were replaced by Lite PC, but the applications from the network. Carr modified only to the extent that he replaced the reference of a service the mere i.”this failed approach, countering Andreas Lady, Germany head of the ICT provider Aastra his comparisons with the power supply from mega power plants are no longer considers latzel on the amount of time.
