Service-Oriented Architecture and Enterprise Architecture, Part 1: A framework for understanding how SOA and Enterprise Architecture work together
The first of a three-part series, this article provides a framework to help you understand how Service-Oriented Architecture (SOA) and Enterprise Architecture (EA) work together. First, get a brief introduction to and definitions of SOA and EA. Then learn about the scope and focus of SOA and EA so you can effectively compare and contrast the two. 		Articles 26 Apr 2007  
 
Service-Oriented Architecture and Enterprise Architecture, Part 3: How do they work together?
If you're adopting a Service-Oriented Architecture (SOA) and developing an Enterprise Architecture (EA) simultaneously -- or planning to -- you'll benefit from this article. The first two parts in this series compared and contrasted SOA and EA and covered problems that can result from not coordinating EA and SOA activities within an enterprise. The authors came face to face with these issues while working on a US$1.6 billion client engagement where both SOA and EA were under development. In this final installment of the series, learn from their experience as they provide guidance to help you address these challenges -- and hopefully avoid costly setbacks. 		Articles 30 Aug 2007  
 
Service-Oriented Architecture and Enterprise Architecture, Part 2: Similarities and differences
In this article, Part 2 of this series, you examine the architecture and the governance models of both Service-Oriented Architecture (SOA) and Enterprise Architecture (EA), and explore their similarities and differences. Then you learn about potential problems that organizations can face if they don't coordinate EA and SOA activities within the enterprise. 		Articles 21 May 2007  
 
SOA meets situational applications, Part 1: Changing computing in the enterprise
As Service-Oriented Architecture (SOA) comes of age, gaining wider acceptance in the enterprise, the Web 2.0 buzz grows louder -- perhaps matching the SOA hype of two years ago. Many clients and colleagues are asking, "What's the relationship between the SOA and situational applications?" "Are they orthogonal or complementary?" "Who cares about the distinction, and are these relevant to two totally different audiences?" This article covers the applicability of Web-based situational applications (SAs) to the enterprise, their relationship to SOA, and how you can use them to improve the current state of corporate IT. Learn about the IBM experience in building the Situational Applications Environment (SAE), which was developed to support the community-based computing that takes advantage of both traditional SOA and emerging Web 2.0 technologies and approaches. Also, examine several SAs, and learn about their business situations and challenges, architectures, tangible business results, technologies that enabled the solution, and the lessons learned.

Elements of Service-Oriented Analysis and Design
Experience from initial Service-Oriented Architecture (SOA) implementation projects suggest that existing development processes and notations such as Object-Oriented Analysis and Design (OOAD), Enterprise Architecture (EA) frameworks, and Business Process Modeling (BPM) only cover part of what is required to support the architectural patterns currently emerging under the SOA umbrella. Thus, there is a need for an enhanced, interdisciplinary service modeling approach. 		Articles 02 Jun 2004  
 
Boost application development with Amazon Web Services, Part 1: How to use the Amazon E-Commerce Service
This tutorial provides an overview of Amazon Web Services (AWS). AWS exposes raw product information and key parts of Amazon.com technology to third-party developers for use in their applications. After describing how AWS works in general, the tutorial focuses on the main AWS service, called the Amazon E-Commerce Service (ECS). As part of this tutorial, you will develop a small Web application that uses ECS to display book and music information.

Make SOA transactional
In the world of enterprise application integration (EAI), it's essential that all participating systems operate under an overarching global transaction so that these systems all return to a consistent state in case of a failure. With the various systems supporting different protocols, the transaction semantics must be propagated across these protocols so they can seamlessly participate in the global transaction. This article walks you through the steps required to make an example of a common integration scenario a transactional integration. 		Articles 10 Apr 2008
