Services Computing Overview Using computing (IT) technology to perform business services more efficiently and effectively

Description of Services Computing- Services Computing covers the science and technology that underlie Business Services and

bridge the gap between Business Services and IT Services. The core technology suite includes Service-Oriented Architecture (SOA) and Web services, business process integration and business performance management, and services innovation research.

- Solution Perspective (Bridging the gap between business services and IT services)

It covers whole lifecycle of services innovation research that includes business componentization, services modeling, services creation, services realization, services annotation, services deployment, services discovery, services composition, services delivery, service-to-service collaboration, services monitoring, services optimization, as well as services management.

1. Business-Centric SOA

1. Business Centric Service-Oriented Architecture (SOA)

Business Value: SOA starts with business!Componentization: An SOA is a component model that inter-relates services (the different functional units of an application or an enterprise) through well-defined interfaces and protocols between these services. Flexibility and Simplification: The interface is defined in a neutral manner that should be independent of the hardware platform, the operating system, and the programming language the service is implemented in. Loose Coupling: Service-oriented architectures are not new, but an alternative model to the more traditionally tightly-coupled object-oriented models that have emerged in the past decades. End-to-End Solution View: Business process, security, trust, and reliable messaging should play a significant role in any SOA. Various Realizations: Web services is just one technology to realize an SOA. An SOA may not use Web services. Expanding Web Services: from simple client-server model to any service-to-service (S2S) interaction model

EA method is represented in a two-dimension chart. The horizontal dimension represents EA design phases with a governance model supervising all phases. The vertical dimension represents important areas in the business of an enterprise which are customer facing, e.g., Service Fulfillment, Service Assurance, and Service Billing. Within each step of the EA process, multiple iterations may be needed, taking various areas into consideration.

Trend: Enterprise Architecture is being enabled by SOA

2.Multi-Dimensional Services Modeling

9



2. Multi-Dimensional Services Modeling (MDSM)

Challenges of Web Services Modeling- Both WSDL and BPEL4WS only focus on describing static

information about a Web service.WSDL describes the basic static information about a Web service,such as its abstract interface, bindings to particular message formats and protocols, as well as the location of the service. BPEL4WS describes the invocation relationships between Web service components within a business process.

- However, Web services inherently contain other information that should be covered, such as their dynamic information and relationships with each other.

MDSM Example: Three-Dimensional Web Services Modeling- Static information describes the descriptions of a Web service. - Dynamic information describes dynamic behaviors of a Web

service, including invocation history of a Web service and some Quality of Services (QoS) measurement, (e.g., its reliability in a specific time frame or its successful access rate).

- Relationship information describes relationships among Web services and their corresponding service providers.

3. Federated Services Publishing and Discovery

11



3. Federated Services Discovery Framework

The federated framework provides a uniform interface for both UDDI-based and WSIL-based service discovery; - It hides the complexity and

differences between UDDI and WSIL programming models.

- Search over UDDI registries and WSIL chains becomes transparent to application developers.

An application developer can use the same interface for any service searching and write all search queries in one document.

5. Adaptive Services Invocation

17



5. Adaptive Service Invocation

Simple Service Invocation (Challenges: what does the number actually represent? What is the unit of the measurement? )

Example Approach: MetaWSDL- Formally define the semantic

information of Web service interfaces and enable automatic parameter adaptation

- MetaWSDL is introduced as a superset of WSDL and is complementary to the current WSDL by enriching the semantic definitions of Web services.

- As a complement of WSDL, MetaWSDL documents should be published to the Internet and be associated with the original WSDL documents. (e.g. WSIL as a tool)

6. Services Relationship Modeling in SOA

In order to represent comprehensive SOA-oriented business relationships, a layered model is introduced.It intends to seek a dynamic and extensible solution by defining a richer and broader range of relationships at various levels oriented for dynamic business service integration. (Extension to Web Services Relationship Language (WSRL))

8. Integration of Web 2.0 and SOA (Data Aggregation Based Collaboration)

25



8. Integration of Web 2.0 and SOA (Data Aggregation Based Collaboration)

A RSS module used for syndicating business resources (site, organization, project, process, people, events, task or activity, documents, annotations) in RSS feeds.Business RSS enables independent modules (Web services) to create self-published, syndicated “capability shows," and gives business message exchange a new distribution method. Receivers may subscribe to feeds using “BRIEF" software (a type of aggregator), which periodically checks for and downloads new content automatically. Some BRIEF software is also able to synchronize (copy) bizcasts to any devices such as browser, handheld devices, wireless phones, as well as any applications.

An enterprise usually needs to collaborate with its value chain of suppliers, partners, and customers for a common goal. Traditional B2B Message Exchange could be replaced with BizRSS
