Distributing the load among a cluster of servers can accelerate a slow running Web Service. Especially a Web Service that consumes a lot of CPU power and that serves a large number of concurrent clients. The open source SOAP intermediary Membrane SOA Monitor now comes with a loadbalancer for Web Services. The URL rewriting functionality of the monitor, that modifies endpoint addresses and schemaLocations in WSDL documents works together with the loadbalancer. The architecture of the balancer is based on some Spring beans and is therefore very flexible. For example, the dispatching strategy that selects an endpoint in the cluster can be exchanged by other implementations.
