Service Oriented Architectures

1. Service Oriented Architectures Presentation By: Clifton Sweeney November 3rd 2008

2. What are Service Oriented Architectures? (SOA) • Provides methods for systems development and integration.

3. What does a business need? • Highly distributable communications and integration backbone.

4. What are we discussing today? • Technologies that make up SOA. • Approaches that unify concepts in SOA. • Extensions of the original concept.

5. Goals • Streamline existing business processes. • Streamline a version of SOA (xSOA) for widespread use. • Incorporate the use of Web Service. • Seem-less running of programs throughout the network to eliminate barriers.

6. General Architecture • Structures large applications as an ad hoc collection of smaller modules called services. • Focused on creating a design style.

8. Bound Pairs • Service interface • Defines the identity of a service. • Service implementation • Implements the work to be done.

9. Services - Characteristics • Everything is a service. • Everything is autonomous. • Everything is invocable.

10. Services - Roles • Client • SOAP to XML • Provider

11. Services - Roles • Service Brokering • Trusted party that forces providers to adhere to common practices.

13. Enterprise Service Bus • Software architecture construct. • Referred to as middleware. • Open bus designed for implementation, deployment, and management of SOA based solutions.

14. Enterprise Service Bus • Responsibilities • Control flow and translations of all messages between services. • Pulls together applications to create assemblies of services to form composite business processes.

17. Successful ESB requirements • Dynamic connectivity • Integration capabilities • Security • Monitoring Health • Scalability for future

18. Enabling Technology in ESB • ESB fuse four types of technologies: • Integration brokers • Application servers • Business process management • Adapters

19. Integration Brokers

20. Application Servers

21. Business Process Management • BPM is the new generation of technology that provides end to end visibility and control over all parts of a long lived, multi step information request that spans multiple applications and humans in multiple enterprises.

22. What does that mean? • BPM software solutions in an ESB include: • Workflow related processes • Process analysis • Visualization techniques www.pega.com

23. Adapters • Provide connectivity • Semantic disambiguation • Translation services between apps and collaborations.

24. Adapters Con’t

25. Extending SOA (xSOA) • SOA could be extended to support capabilities such as service orchestration, intelligent routing, provisioning, and service management. • Guarantee the integrity of data and security of messages.

26. xSOA • Is an attempt to streamline SOA. • Its layers embrace a multi-dimensional, separation of concerns in such a way that each layer defines a set of constructs, roles, and responsibilities.

27. xSOA con’t

28. xSOA Con’t • xSOA incorporates a service composition tier to offer necessary roles and functionality for the consolidation of multiple services into a single composite service.

29. Successfully build and deploy a distributed SOA you need? • Service enablement • Service orchestration • Deployment • Management
