Cloud Service Architecture and Related Standards3,2

Abstract

Many enterprises plan to migrate their IT infrastructures to Cloud-based infrastructures through a phased approach. With the existing enterprise systems having arcane and inconsistent interfaces, the implementations have a tendency to develop into more complicated process flows, consisting of many subsystem interfaces to accommodate existing processes. In some cases, enterprise IT systems need to duplicate some functions to maintain consistency of business information so that enterprises can make sound financial decisions. These issues, however, are not the intent of this book. Instead, our approach is to look at the Cloud service architecture as a clean sheet scenario, peeling off issues and challenges layer by layer to reveal relevant, ultimate solutions.
