How do we reliably and repeatedly combine results from several distributed services on the web to produce a result for a user? Service chaining is the term commonly used for the process of organizing disparate web based services into an orderly process. For instance, a raw image is sent to a service that performs a coordinate transformation. This services sends the transformed image to a classifier service that processes the image to highlight areas of active fire. The result of this service is sent to a user’s client along with other geospatial data such as vegetation overlays, transportation. Service chaining will play an important role in future capabilities. … Web servers
