Abstract
The functionality of applications is increasingly being made
available by services. General concepts and standards like SOAP,
WSDL, and UDDI support the discovery and invocation of single web
services. State-of-the-art process management is conceptually
based on a centralized process manager. The resources of this
coordinator limit the number of concurrent process executions,
especially since the coordinator has to persistently store each
state change for recovery purposes. In this paper, we overcome
this limitation by executing processes in a peer-to-peer way
exploiting all nodes of the system. By distributing the execution
and navigation costs, we can achieve a higher degree of
scalability allowing for a much larger throughput of processes
compared to centralized solutions. This papers describes our
prototype system OSIRIS, which implements such a true
peer-to-peer process execution. We further present very
promising results verifying the advantages over centralized
process management in terms of scalability.
