Self-tuning BPEL Processes

摘要

The performance of BPEL processes depends on the composing web services. Monitoring web service performance and adapting to changes in service performance are essential for creating self-tuning BPEL processes. Unfortunately, BPEL supports neither performance monitoring nor dynamic adaptation mechanisms. In this paper, we present a monitoring and rebinding infrastructure for BPEL that transparently enhances existing BPEL processes with self-tuning behavior.
