This IBM® Redbooks® publication discusses the real world experience of an enterprise that developed and implemented IBM z/OS® cloud services.

Embarking on a cloud strategy can be overwhelming. No sh...
IBM CICS and the Coupling Facility: Beyond the Basics
It's easy to look at the title of a book and think "that's old news" or "I already know all there is to know on that subject."

The main focus of the book is lessons learned from the impleme...
