Title:
"Beyond Middleware and QoS - Service-Oriented Architectures - Cult or
Culture?"
Abstract:
State-of-the-art middleware such as CORBA, RMI or .NET Remoting
represents a stack of interoperability layers to connect different
islands of code. While all these existing solutions are widely used for
the development
of commercial and industrial software, they still lack essential
features:
First of all, there is no accepted middleware standard to connect
different technology platforms with each other. And second, standard
middleware
promotes a tight coupling between peers. SOA principles introduce loose
coupling which is important when even small parts of a distributed
system
are not under control of the developers. One implementation of these
principles, XML Web services, are capable of bridging heterogeneous
languages, platforms, and middleware. On the other hand, complain about
immature, missing or even competing standards for XML Web services. And
it
still seems unclear how component-based technologies and services fit
together. The keynote tries to illustrate how the upcoming universe of
middleware, services and components could look like. Not only from a
functional perspective but also keeping quality of service issues in
mind.
