Background on Service Oriented Architecture CORBA MS COM EJB component model Web Services

SOA Definition Service Oriented Architecture is: An Application Architecture that is designed to achieve loose coupling among interacting software applications. SOA provides greater flexibility in developing, integrating, and managing Enterprise Applications

SOA Definition 2 Service-Oriented Architecture is: An application architecture in which all functions, or services, are defined using a description language and have invokable interfaces that are called to perform business processes. Each interaction is independent of each and every other interaction and the interconnect protocols of the communicating devices. Because interfaces are platform-independent, a client from any device using any operating system in any language can use the service.

SOA Definition 3 Service-Oriented Architecture is: A set of components which can be invoked, and whose interface descriptions can be published and discovered World Wide Web Consortium (W3C)

Service Definition Service is: A unit of work done by a service provider to achieve desired end results for a service consumer. Both provider and consumer are roles played by software components ServiceProviderServiceConsumer Service Request Service Response

Services and SOA A service in SOA is an exposed piece of functionality with three major properties: The interface contract to the service is platform-independent. The service can be dynamically located and invoked. The service is self-contained. That is, the service maintains its own state.

The Service-Oriented Approach SOA is a design and a way of thinking about building software components. – Use-Based Solely Published Contract – Network Addressable Interface – Stresses Interoperability – Dynamically Discovered and Used

The Benefits of a SOA Better Return on Investment Code Mobility Focused Developer Roles More Security Better Testing/Fewer Defects Support for Multiple Client Types

The Benefits of a SOA (2) Service Assembly Better Maintainability More Reuse Better Parallelism in Development Better Scalability Higher Availability

“Integration accounts for 35% of Application Implementation and Maintenance Costs” - Gartner Group

Today Integration Point-to-Point Integration is difficult to manage and maintain over time Proprietary Integration Brokers and Messaging Solutions means customers are ‘locked in’ to vendors Integrating Integration products is commonplace License and Consulting costs are too prohibitive for mainstream adoption
