There are various technologies for IBM i that are available in support of web services. The following sections look at some of the most popular technologies from two perspectives: the web service provider perspective and the web service consumer perspective. 

Who is the consumer and who is the provider for a web service?

Consumer and provider of a web service request

The consumer is the client application (for example, browser or client application). The client application might use SOAP or REST to consumer the web service.
