Services Computing and ecosystem services chapter quiz answer

1. The combination of a plurality of services and services constituted assembled together to provide the functionality of a business task or process implemented. If further service combinations can be packaged as a service, the service can be considered a combination of service implementation.

2. As long as there is inventory in the service, whether it is application services, business services or service orchestration, can be used as sub-assembly services are services portfolio.

The service whether directly meet the needs of consumers, the service can be ecosystem (Services ecosystem) in services are divided into vertical (Vertical) and service level (Horizontal) service. Therefore, when performing the service system construction, you can advance the service partition for both types, and in accordance with its characteristics, different design principles apply, respectively, for analysis and design. ×

4. Due to the lack of uniform standards organizations and standards, there is currently no mature service-oriented programming languages, but with the development of service-oriented and generic Web Service standards, service-oriented programming languages ​​is expected to occur in the future, and to provide for service fully supports implementation. ×

5. The objectives include service-oriented technology: flexibility, scalability, robustness, reusability and efficiency, to meet business needs. Organizational flexibility, inherent interoperability, vendor selection diversification, alliances, business and technical consistency, reduce IT investment, increase return on investment: commercial.

6. From the perspective of the scope, service oriented computing services are often based on a scope of ecosystem services; in object-oriented computation, the scope of the object are often based on a software system.

7. From the viewpoint coupling, in object-oriented computation, if we carefully divided according to function, to reach the "relative independence" between the modules and the module, we can achieve the similar service-oriented computing loose coupling. ×

8. service portfolio provides flexibility and reusability. However, due to the particular sub-services can participate simultaneously to a plurality of business processes, "bottlenecks" and the "single point of failure" problems such combination business functions and services implemented in poor reliability in object-oriented implementation of similar functionality. ×

9. In the object-oriented computation, code reuse through inheritance be implemented library functions and class members. Service-oriented computing, code reuse in service levels.

10. As the member is a network service using service-oriented computing system constructed out service, a network application is natural.
