CoreGRID partner (WP3:
Programming models) |
|
|
Overview |
NEReSC has been involved in a
number of research
projects in the area of internet-scale/Grid computing. In order
to support our research projects, we have been investigating issues
related to the architecture of Web Services and
message-oriented/event-driven programming models for their
implementation. |

Service- and Message-Orientation |
Service-orientation is the contemporary architectural paradigm of
choice for developing distributed applications. The paradigm is
based on the concepts of “services” and “messages” where
applications orchestrate message exchanges between their constituent
services. Although the underlying service and message abstractions
may seem trivial, they are the basis for constructing
loosely-coupled systems which are scalable, reliable, and robust.
While the principles of service-orientation can be applied to the
implementation of applications using many distributed computing
technologies, it is the advent of XML together with the set of
existing and emerging Web Services technologies and their
surrounding hype that has refocused attention on service-oriented
architectures. Our focus is on a message-oriented architectural
paradigm for Web Services. |
