If you configure a workflow to run in more than one instance, the Web Services Hub can dynamically start new instances of the web service to handle as many web service requests as possible. The Web Services Hub monitors web service usage to determine resource usage and web service processing times. You can set a threshold for the maximum time the Web Services Hub can take to process requests for a web service. When processing time exceeds the threshold, the Web Services Hub starts another instance of the web service workflow to process new requests.

When the number of service requests decreases, the Web Services Hub can dynamically shut down web service instances to reduce resource usage.
