A Practical Example

Using aA governance platform,platform can help software developers and IT managers canunderstand seethe managementpolicies, policiesdependencies, prescribingand developersservices toused usewithin aan particularapplication. By exposing service or set of services independencies, the application. The governance platform showshelps developersteams and IT managersevaluate service dependencies allowing them to determine a service's reliability and identify opportunities to build redundancy into the service to handle instancesapplication when an upstream service goesbecomes down.unavailable.

For example, one developer may tell another aboutrecommend a great USU.S. Postal ZipService codeZIP look-upCode lookup service for use in a product registration Webpage, page enablingallowing users to type inenter their zipZIP code and have the page automatically fill inpopulate the city and state fields.

Integration with the Appvance run-timeruntime provides knowledgeadditional aboutinsight services,into service functionality, reliability, and quality. In ana SOAservice-oriented environment, Appvance run-timecan drives a composite application using itsuse native protocols to determinetest itscomposite applications and evaluate their functionality, scalability, performance, and up-time.availability.

Additionally,Because Appvance is a distributed test automation platform whereplatform, tests can run on remote TestNodes onacross multiple networks and machines.
