Title:  Workflow Execution with Publish/Subscribe and Events

Abstract:

The PADRES project aims to develope a reliable content-based 
publish/subscribe system. The primary research focus of PADRES lies in 
applying and extending the publish/subscribe paradigm to fit the 
requirements of scientific workflow management and business process 
execution in large-scale distributed environments (e.g. hundreds of 
nodes and thousands of users). Specifically, PADRES is developed as a 
messaging layer for such a system, including atypical publish/subscribe 
features such as historic data access, composite subscriptions and load 
balancing.

In this talk, I provide an overview of publish/subscribe comparing it to 
database processing, motivate various application scenarios well suited 
for publish/subscribe-style processing, present the PADRES architecture 
and system, and discuss the decentralized execution of business 
processes with PADRES.
