Web services allow processes to communicate by passing XML documents over well known ports and protocols (typically HTTP). The SOAP and WSDL recommendations promote features such as interoperability and loose coupling that enable web service clients and the services they access to be written in different languages and run on different platforms. For example, a C#® client running on Windows® can access a Java™ web service running on Linux™.
