- Standard way of describing a service via WSDL
- Standard message interchange via SOAP.
- Discovery occurs through UDDI registry - not a dynamic network of peers.
- Central registry for publishing services
- Service broker that maintains the registry
- Service requestor that uses the borker to find services
Web
Services rely heavily on centralized servers running services. However,
the client side is free to discover and use a variety of services. Web
Services appear somewhat P2P like, but there is no dynamic network and
thus, for the time being remains largely server-reliant.
Web Services seem to be a reasonable complimentary platform with P2P applications requiring centralized services (more later).
