ESB is a key ingredient to build an SOA infrastructure, but it's not a must. Even with an ESB, if industry best practices and patterns are not followed, users will end up in a mess. This book will teach you the essentials to get started with WSO2 ESB and solve the most commonly-faced integration problems.</p> <p>The book starts by explaining the need for an ESB and the problems it solves. It will cover the most widely-used enterprise integration patterns, including Content Based Router, Dynamic Router, Splitter, Aggregator, Scatter &amp; Gather, Publish &amp; Subscribe, Detour, Service Chaining, Content Enricher and Message Broker. Learn how WSO2 ESB can bring third-party business messaging systems such as SAP, FIX, and HL7 into the SOA world, as well as how to integrate the Twitter connector into your business messaging flow.</p>
