This application is an end-to-end sample application for .NET Enterprise Application Server technologies. It is a service-oriented application based on Windows Communication Foundation (.NET 3.0) and ASP.NET, and illustrates many of the .NET enterprise development technologies for building highly scalable, rich "enterprise-connected" applications. It is designed as a benchmark kit to illustrate alternative technologies within .NET and their relative performance. The application offers full interoperability with Java Enterprise, including IBM WebSphere's Trade 6.1 sample application, and newly provided implementations on Oracle Application Server 10G (OC4J) and Oracle WebLogic Server 10.3 (Oracle implementations included with the download below). As such, the application offers an excellent opportunity for developers to learn about .NET and building interoperable, service-oriented applications.
Service-oriented architecture has proven to be a boon in the computing world. At its core, SOA provides enterprise patterns for systems development and integration where legacy systems are viewed as discrete business capabilities and packaged as standards-based services interfaces. SOA also typically describes an IT infrastructure that allows different applications to exchange data with one another as they participate within business processes. Over the past few years, SOA has grown almost exponentially in popularity, becoming one way for companies to knit together applications and processes in a flexible, reusable and cost-effective way. SOA separates functions into distinct units, or services, which developers make accessible to users over a network, ideally allowing them to combine and reuse them in the creation of business applications. These services communicate with each other by passing data from one service to another or by coordinating an activity between two or more services.
The ActiveBPEL™ engine is a robust runtime environment that is capable of executing process definitions created for the Business Process Execution Language (BPEL) standard.
Confusion about Services Based Architectures [SBA, SOA, EDA, ...] has been created by a number of industry elements. Industry critics like Forrester first used the term Services Based Architecture until 2000 when Gartner came up with their own term Services Oriented Architectures (SOA). Forrester was still using the term SBA in 2002. Gartner next created the term Event Driven Architecture and has now come full circle back to SOA 2.0 (supporting both SOA and EDA like the original SBA).
For those unfamiliar with business-driven architecture, I believe the most viable, agile architectures will be comprised of a blend of architecture strategies, including (but not limited to) service-oriented architecture, event-driven architecture, process-based architecture, federated information, enterprise integration and open source adoption.
InfoQ has gathered a virtual panel of Enterprise Architects who have lived and implemented SOA for most of this decade to better understand what SOA means to IT in 2009.
