Dynamo: Dynamic monitoring of WS-BPEL processes

Dynamo advocates that pre-deployment validation and testing are intrinsically inadequate for tackling the ephemeral and rapidly changing context in which service oriented applications are deployed. Validation must be shifted to run-time and continuous monitoring must be introduced. We propose a simple architecture that, through specific and simple annotations, allows for the automatic creation of instrumented WS-BPEL processes. These processes interact with a special-purpose proxy that enacts the monitoring activities and permits us to dynamically set the level of monitoring through use of a web-based interface.
