Service Oriented Architecture: An Integration Blueprint

Overview of this book

Service Oriented Architecture (SOA) refers to building systems that offer applications as a set of independent services that communicate and inter-operate with each other effectively. Such applications may originate from different vendor, platform, and programming language backgrounds, making successful integration a challenging task. This book enables you to integrate application systems effectively, using the Trivadis Integration Architecture Blueprint, which is supported by real-world scenarios in which this Integration Blueprint has proved a success.This book will enable you to grasp all of the intricacies of the Trivadis Architecture Blueprint, including detailed descriptions of each layer and component. It is a detailed theoretical guide that shows you how to implement your own integration architectures in practice, using the Trivadis Integration Architecture Blueprint. The main focus is on explaining and visualizing the blueprint, including comprehensive descriptions of all of its layers and components. It also covers the more basic features of integration concepts for less experienced specialists, as well as shedding light on the future of integration technologies, such as XTP and Grid Computing. You will learn about EII and EAI, OGSi, as well as base technologies related to the implementation of solutions based on the Blueprint, such as JCA, JBI, SCA and SDO.The book begins by covering fundamental integration for those less familiar with the concepts and terminology, and then dives deep into explaining the different architecture variants and the future of integration technologies. Base technologies like JCA and SCA will be explored along the way, and the structure of the Trivadis Integration Architecture Blueprint will be described in detail, as will the intricacies of each component and layer. Other content includes discovering and comparing traditional and modern SOA driven integration solutions, implementing transaction strategies and process modeling, and getting to grips with EDA developments in SOA. Finally, the book considers how to map software from vendors like Oracle and IBM to the blueprint in order to compare the solutions, and ultimately integrate your own projects successfully.

Grid computing/XTP scenario

This scenario shows how the business pattern for grid computing and Extreme Transaction Processing (XTP) technologies described in Chapter 1 can be implemented.

Implementing the grid computing business pattern

The grid computing business pattern can be implemented using a data grid framework and is shown in the following diagram:


  • An application makes a change to an object in the distributed cache.

Primary flow:

  1. 1. The data grid ensures that the modified object in the distributed cache is updated.

  2. 2. The relevant backup data is updated.

  3. 3. Depending on the topology of the cache, the data may be distributed across the entire cluster or only across certain computers.

  4. 4. Applications can register their interest on changes to data by applying a suitable filter. In this case, they receive an event whenever the data has been changed.
