Over the past few years in the field of information technology (IT) has developed a new paradigm - cloud computing. Although cloud computing is just a special way of providing computing resources, and not a new technology, they have revolutionized the way information and services are provided.
Initially IT was dominated by mainframes. Over time, this rigid configuration gave way to the client-server model. The modern IT industry is becoming increasingly mobile, pervasive and, of course, cloudy. But this revolution, like any other, contains the old components from which it evolved.
Thus, in order to correctly understand cloud computing, it must be remembered that they essentially inherit the previous systems genetically. In many ways, a turning point means "back to the future," and not a final end to the past. In this amazing new world of cloud computing, there is room for innovative collaboration of cloud technology and proven effectiveness of previous systems, such as powerful mainframes. This true change in the approach to computing provides IT staff with enormous opportunities, allowing them to take change management for themselves and use them for the benefit of themselves and their organization.
