Abstract:
Globally distributed services need more than location transparency.
An implementation of such a service has to scale to millions of users
from all over the world. Those users may have different and varying
quality-of-service requirements that have to be considered for an
appropriate distribution and installation of service components. The
service also has to scale to thousands of administrative domains
hosting those components. AspectIX is a novel middleware architecture
which extends CORBA by a partitioned object model. A globally
distributed service can be completely encapsulated into a single
distributed object which contains not only all necessary components for
scalability (e.g., caches and replicas) but also the knowledge for
self-organization and distribution of the service. For distribution
and installation of components, the service considers object-external
policies to achieve administrative scalability.
