A recommended approach to building a service is to design its physical contract prior to its underlying solution logic. This “contract first” process is very effective at ensuring
that contract design standards are consistently incorporated. It also allows us to tune the underlying logic in support of the service contract, which can optimize runtime performance and reliability.

D. There are four primary types of meta information we are interested in abstracting when applying this principle: technology, functionality, programmatic logic,
and quality of service.
E. Service Abstraction raises design-time considerations associated with the
technical service contract, service design specifications, and source code, as
well as non-technical contract documents, such as SLAs.

What of the following statements is (are) False?
A. Encapsulation refers to the logic, resources, and information contained
within the service boundary. A service, in its entirety, is comprised of a contract and what it encapsulates.
B. Autonomy refers to the parts of what the service encapsulates that are exposed to and
hidden from consumer programs outside of the service boundary. In other words, the
application of this principle determines how much of the encapsulated logic we make
public.
C. The only meta data typically not directly affected is quality of service information. Regardless of what is encapsulated, it is usually considered preferable for these details to be consistently documented, published, and shared.
D. Service Abstraction raises design-time considerations associated with the
technical service contract, service design specifications, and source code, as
well as non-technical contract documents, such as SLAs.
E. Once a service is implemented, its abstraction levels are established and difficult to change thereafter. This introduces the potential for risks that can typically be avoided at design-time.
B. Autonomy refers to the parts of what the service encapsulates that are exposed to and hidden from consumer programs outside of the service boundary. In other words, the application of this principle determines how much of the encapsulated logic we make public.
The goals behind Service Reusability are tied directly to some of the most strategic objectives of service-oriented computing:
• To allow for service logic to be repeatedly leveraged over time so as to achieve an increasingly high return on the initial investment of delivering the service.
• To increase business agility on and organizational level by enabling the rapid fulfillment of future business automation requirements through wide-scale service composition.
• To enable the realization of agnostic service models.
• To enable the creation of service inventories with a high percentage of agnostic services.
