There is no better kept secret in the computer industry than the All-Everything Machine. Most people simply have not heard about it. Another secret is that from "time immemorial," IBM has made the finest, most architecturally elegant, most usable, most productive, and most affordable computer system. That system is in its fifth incarnation as of mid 2016, and its 30-year oldadvanced underpinnings provide the greatest business value in the industry.That's an awful long time for any company to keep such a secret but don't expect IBM to keep the secret for much longer. Big Blue has begun to focus on claiming the proceeds from the many years of advanced development that culminated in its newest version of the All-Everything Machine. That's what this book is all aboutUsing a 40-year old "nobody else can afford to build one" architecture, IBM continues its technology lead by far compared with all the other server machines. One would have to conclude that this technology is about 40 years ahead of its competition even before you factor in that forty years have passed from its conception and IBM's developers have not stood still. IBM calls the box a "mainframe for the masses" and Big Blue is now shaping its Z13 mainframe chips to be as close to this one time small system design as possible.When you finish this book, you will understand why IBM is proud to have built the finest computer system in the world, and you will have a good idea of the value such a machine can provide for your business.
