Introduction
Barely 25 years ago, we all started surfing the World Wide Web. Around
the same time, we started using mobile phones on a regular basis. At
that time, however, not many people thought about bringing those two
technologies together. Even fewer people expected the combination to
become as popular as it is today.
If you remember that time, you’ll know that companies like Google
didn’t even exist. Amazon wasn’t around yet, and everyday devices such
as iPods, iPhones, or iPads weren’t even invented. Even Nokia—for
years to come one of the leading companies for mobile phones—was
just getting started, and look how their role has changed. When you
remember—and we assume some of you do—the past 25 years, you can
easily see how fast things move in the IT area.
Let’s fast forward to today. In today’s world, not only can you surf the
web using your PC, you can also use your smartphone, tablet, phablet,
TV, or gaming console—to name only a few. Because of this, we face the
challenge of providing business applications that address a virtually end-
less number of consumption channels. Furthermore, to remain compet-
itive, we see a necessity to implement social and technological trends
alike.
This book is about a product that enables you to implement those trends
for SAP Business Suite applications: SAP Gateway. The book takes you
on a tour to learn everything you need to know about SAP Gateway. If
you are new to SAP Gateway and its concepts, you should take this tour
from Chapter 1
to Chapter 16 in one read. If you already understand
some of the concepts and technologies involved, we did our best to
allow you to take detours, start in the middle of things, and jump
around if you like. To make the tour as convenient as possible for you,
the book is structured not only in simple chapters but also into several
overarching parts.
