A WS gives you
- • Language, Operating System, and Implementation independence
- • Loose coupling between components/applications
- • Abstract way of exposing what each service offers
When we have components that are loosely coupled, can be composed easily,
and are independent, we have a system designed using a "Services Oriented
Architecture" (SOA).
In the past, SOAs were built from CORBA/IDL components, JINI/RMI, or other
similar approaches, none of which combined the characteristics provided by
Web Services.
But, at the present time, Web Services do support some of the more
interesting parts of SOAs: orchestration and dynamic composition of
services, reliable aysnchronous communication, etc. Although there are
specs in the works for all of these aspects.
