With the advent of distributed computing, application management is driven into a new era. In this world, application quality of service, resource availability at different domains, and user requirements, are combined in a dynamic, synergistic, and geographically broad cooperation. We present an architecture and initial implementation of a middleware that satisfies user requests according to expected requirements, distributes networked resource load beyond the local environment, and respects the logical constraints of different domains. Static characteristics of resources are advertised as service offers using the CORBA trading service, while dynamic changes in their state are reported using the CORBA event service. We present a model where, unlike traditional high-level management systems, resources compete to satisfy application requirements
