Introduction

Abstract

Implementing distributed systems, let alone systems that provide real business value, has been challenging to accomplish over the years. Non-distributed systems have always been the first type of application that developers start creating. As such, when developers start to enter the realm of distributed systems, they often take many issues for granted that pose significant challenges. These challenges might be obvious to veteran developers that have had to create hosts for these distributed processes, but they still seem to rear their ugly heads. The biggest challenge consistently has been that of tightly coupled systems. It becomes prohibitively expensive to make changes as needed to meet the demands of the business when systems contain tightly coupled components.
