There are significant changes in progress in the way in which IT is delivered, how it is used and consumed, and by whom it is consumed. The drivers are relentless. Massive growth in scale, including the number of users, their geographic locality, huge growth in the amount, type and velocity of data, and the increasing desire to not only provide access and safety, but create value for the company and it's customers from the data. This book takes a very methodical approach to describing the drivers, the architectural choices, and very importantly, identifying the stress or breaking points so that you can deal with them ahead of time and not as your project is in crisis.
