Services-based enterprise integration patterns made easy, Part 1: The evolution of basic concepts
This series of articles explains services-based enterprise integration patterns in an easy-to-understand, step-by-step way. In this installment, Part 1 of the series, you learn about the two earliest integration patterns -- data sharing only and remote procedure call (RPC) -- which help introduce the concepts of service provider and service consumer, platform independence, and connectivity. Exploring RPC helps you get familiar with the basic steps necessary for two applications to share functionality. This article also includes a general description of the concepts of loose coupling, code reuse, and layering and componentization. Part 2 of the series will continue the discussion of the early patterns, while Parts 3 and 4 cover the Service-Oriented Architecture (SOA)-based integration patterns, including examples.

Services-based enterprise integration patterns made easy, Part 4: Enterprise service bus
The first three articles in this series covered the basic concepts necessary to develop services-based integration patterns and explained the various components and standards that, together, are known as Web services. Web services are designed to deal with some of the heterogeneity found in a large enterprise. However, Web services alone aren't enough to provide a complete solution to the heterogeneity problem. In this installment, Part 4 of this series, learn about the enterprise service bus, which, along with Web services, completes services-based integration patterns. 		Articles 12 Dec 2008  
 
Services-based enterprise integration patterns made easy, Part 3: Web services and registry
Part 1 and Part 2 of this series covered the basic concepts necessary to develop services-based integration patterns. This article, the third in the series, and the upcoming Part 4 further develop these ideas so the services-based integration patterns become full-blown services-based patterns. This article in particular deals with the components that are together commonly referred to as Web services, which were originally designed for services that can be accessed over the Internet. You'll also see that many of the Web services components can be used with services that don't use the Internet and that only require a network connection. 		Articles 14 Apr 2008  
 
Services-based enterprise integration patterns made easy, Part 2: More on the evolution of basic concepts
This installment, Part 2 of the series, picks up where you left off in Part 1. Now that you've learned about the two earliest integration patterns -- data sharing (socket programming) and remote procedure call (RPC) -- you continue developing the basic concepts. Check out two more developed patterns: distributed objects and asynchronous messaging. Explore the concepts of language independence, declaration of service interfaces, rudimentary ideas of publication and discovery of services, and basics of the enterprise service bus (ESB).
