Guide to SOA and the cloud

A few years ago, SOA and the cloud were coupled only to indicate that the latter was driving out the former. Now, some experts are starting to view the relationship between the two technologies more positively.

Introduction

With the emergence of cloud computing and cloud applications, some people believed the new technology would make service-oriented architecture (SOA) obsolete. While some still hold that belief, others have found SOA to be very advantageous to the cloud. The first section of this guide covers the relationship between SOA and the cloud, and the second goes into other architectural concepts, such as representational state transfer (REST). Also included are a quiz and key terms. Read on to find out more about the relationship between SOA and the cloud.
