RESTful services on the grid are possible, and even fundamentally
compatible with our present security model, although not a lot of
standardization work has yet been done. One of the distinctions
between grid and cloud computing so far -- two terms that are equally
difficult to define -- is that OGSA has clung so tightly to SOAP that
lighter-weight communication mechanisms as used in the cloud are not
as popular for production services, and hence not supported out of the
box in any (or at least most) grid stacks.
Progress is possible, though -- see http://code.google.com/p/rest-client/
for example.

Web Services denotes a standardized system for applications to
exchange
information over networks through a network firewall, using a
combination of
HTTP -- low-level communications protocol
SOAP -- for XML message encoding and exchange
WSDL -- (Web Services Description Language) describes available Web
Services
A Web Service is a program that processes SOAP messages coming
through a
network. In operation, it generates a proxy program that manages
communications on behalf of a client application.
The standardized Web Services include
WS-Security
WS-Addressing
WS-Notification
WS-Reliability
WS-Transaction
