Each service
provides its functionality to the rest of the system as a well-defined interface described in a
formal mark-up language, and the communication between services is both platform- and
language-independent. Thus, modularity and re-usability are ensured, enabling several
different configurations and achieving multiple business goals. The first service-oriented
architecture relates to the use of DCOM or Object Request Brokers (ORBs) based on the
CORBA specification.
A service is a function that is well-defined, self-contained, and does not depend on the context
or state of other services. Services are what you connect together using Web Services.
A service is the endpoint of a connection. Also, a service has some type of underlying
computer system that supports the connection that is offered. The combination of services,
both internal and external to an organisation, makes up a service-oriented architecture. The
technology of Web services is the most likely connection technology of service-oriented
architectures. Web services essentially use XML to create a robust connection.
