2. is a platform for developing and managing composite applications
3. Composite Application •  Architected as a set of modular, reusable services •  Has both loosely and tightly coupled parts •  May be distributed or may run in a single process •  Often requires integration with legacy and third-party systems •  Typically has an interoperability layer (Web Services or REST) as well as an internal communications (MOM) layer
4. Platform •  Scales up to distributed environments and scales down to small, single processes. •  Ubiquitous. Deploy standalone, in a Servlet container, in a Java EE application server, as part of an automated test environment (Maven, Ant). •  Extensible and customizable. Create features, configure custom runtime profiles. •  Standards based. Service Component Architecture, Spring, Web Services, JAX- RS, JPA/Hibernate.
5. Benefits Reduced Complexity Architectural Consistency Improved Testability Enhanced Reuse
6. Reduced Complexity Communications are abstracted so applications are not polluted with boilerplate API calls. Remote calls – synchronous and asynchronous – are simple Java invocations. public class ServiceClient {! !@Reference! !protected Service service;! !public void invoke() {! !!Message message = …! !!service.call(message);! !}! }! Service Service Client JMS Web Services Communications Fabric Communications Fabric
7. Enhanced Reuse Services can be exposed over multiple transports and protocols through minimal configuration <component name="LoanService”>! !<implementation.java class=”…."/>! !<service name="LoanService">! !!<binding.ws uri="wsloan"/>! !</service>! !<service name="RsLoanService">! !!<f3:binding.rs uri="/rsloan"/>! !</service>! !<service name="LoanGateway">! !!<f3:binding.file location="receive.queue”/>! !</service>! !<reference name="responseQueue">! !!<f3:binding.file location="response.queue"/>! !</reference>! </component>! REST LoanService Web Services File System Communications Fabric
8. No communications API calls makes distributed applications unit test-friendly and integration testing lightweight. Remote services can be mocked. Improved Testability public class ServiceClient {! !@Reference! !protected Service service;! !public void invoke() {! !!Message message = …! !!service.call(message);! !}! }! Remote service is mocked
9. Services are assembled through configuration, providing a unified model for modularity and communications as well as the ability to holistically design an application architecture. Services can be connected via synchronous request-reply, asynchronous one-way and pub/sub patterns. Architectural Consistency REST Web Services File System Channel Database
