Self-tuning BPEL processes

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.
