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.
