Web services is an Internet technology that enables businesses to provide their services, and to discover the services of other businesses. These services are self-contained, self-describing modular applications that businesses can publish, discover and invoke across the Web. This publish-discovery mechanism facilitates B2B communication by enabling business applications to directly connect to other business applications.

These systems may then interact with the Web Service in a manner prescribed by its definition, using XML-base messages conveyed by Internet protocols.
