Web Services are a natural fit for building distributed computing platforms. Which of the following
qualities of Web Services make them suitable for distributed computing?
A.
WSDL,SOAPand XML promote language and platform Independence and interoperability
B.
WSDL can be used to define components that can be distributed in multiple servers.
C.
UDDI allows services deployed in a distributed infrastructure to be discovered and consumed.
D.
Web Services are deployed to the web tier of the distributed architecture.
Explanation:
Web Services are a natural fit for building distributed computing platforms.
* WSDL, SOAP, and XML promote language and platform independence and
interoperability.
* UDDI allows services deployed in a distributed infrastructure to be discovered
and consumed.
* Simple Object Access Protocol (SOAP) enables service binding and invocation
using standards based protocols such as HTTP and JMS.
* The platform for SOA should support the WS-* standards
Note: Openness is the property of distributed systems such that each subsystem is
continually open to interaction with other systems. Web services protocols are
standards which enable distributed systems to be extended and scaled. In general, anopen system that scales has an advantage over a perfectly closed and self-contained
system.
