Abstract

An integrated service selection model selects a service instance from a given repository or registry using a combination of general query and rule based selection process. First it selects comparable instances into a group using a query string. The group is further monitored to consider all aspects of operations to select the specific instance to render the service.

Integrated Service Selection Model for Web Services

  Disclosed is a method that will process multiple service selection criteria at one place where a common decision model is provided. The process spans on two loosely related stages. The first stage is to use a general query against a registry or UDDI to identify a list of similar services into a cluster like Service Desk. The second stage is to apply diverse criteria real time during the operations phase to select a specific service instance for a service request. This selection model is further decomposed into dynamically re-configurable primitives such that multiple disparate decision factors can be aggregated together to support comprehensive business needs without resort to manual coding. The selection model is self-adjusting by calculating the aggregation results continuously from changes of decision factors.

As an example, a business could start with a simple selection criteria that assigns service requests to a pool of Web Services instances queried from a private registry or public UDDI on a random basis. As the business grows, it can add "time" as a new factor and assign service requests based on other directives (round robin, random, etc.) as well. Other factors not viewed by the traditional resource load balancing sense can now be added to the selection model and processed in a common approach. Likewise, proximity and locale types of decision factors are also included.
