Building SOA with Tuscany SCA

Fri, 09 Nov 2007 08:30:00 EST

Many articles have already been written about service-oriented architecture (SOA) and Service Component Architecture (SCA), for example, see references [1] and [2]. In this article we'll focus on a freely available, open source implementation of the Service Component Architecture that provides a simple way to implement SOA solutions. This SCA implementation is being developed in the Apache Tuscany Incubator project. The project started in 2006 and is being used by many who are looking for a simple SOA infrastructure. The recent Tuscany SCA version 1.0, which was released in September 2007, supports the Service Component Architecture specifications 1.0.

Real SOA

SCA is a powerful and simple business level programming model that extends prior approaches to be able to implement services based solutions. SCA defines how services can be described, assembled, and deployed in a meta-data driven fashion, independent of an implementation language and a deployment platform. The approach is based on the idea that each business function consists of one or more components brought together into a composite application. These, in turn, are composed into a network of services that create specific business solutions.

Real SOA - Web Services and Service Oriented Architecture

A challenge facing many organizations is how to quickly and effectively react to frequent changes in business requirements, whilst improving productivity and reducing costs. To achieve this, you need a flexible infrastructure that can meet the demands of a changing marketplace and seize emerging opportunities. To address this challenge, Service Oriented Architecture (SOA) promotes an architectural approach that replaces rigid proprietary systems with heterogeneous, 'loosely-coupled' services. The Service Component Architecture (SCA), along with Service Data Objects (SDO), makes this architectural concept a reality and provides the programming model to build SOA solutions for agile businesses.

Service Component Architecture (SCA) is a simple model for creating service-oriented applications. This article highlights the benefits of SCA and introduces SCA concepts by walking through an example. The example has been developed using the Apache Tuscany open source project (http://incubator.apache.org/tuscany/). All the sample code in this article is licensed under the Apache License 2.0 (www.apache.org/licenses/LICENSE-2.0) and the resources with the article gives a link to the sample files. Both the Apache Tuscany and PHP SCA_SDO (http://pecl.php.net/package/sca_sdo) projects provide a free service oriented infrastructure for creating, packaging, deploying, and managing applications built with the SCA programming model.
