WEBEN Web Chaching Data Solutions Definition: Weben is an enterprise application which aims to decrease the response time and increase the performance of the all kinds of http based query service (SOAP, RESTFul, for example) exposed by service provider systems by storing the service data in a cache system and returning the response from the cache when the same query is made again and decrease the load of service provider system by reducing the consumption of resources such as CPU, Memory, I/O. Needs met by Weben: The basic approach applied with Weben is keeping query data of client applications in a cache with its input criteria. In this way when the same query is received from the same service with the same input criterion, this request will be sent directly to the client application via the cache without calling back-end system. Hereby this will result in a significant improvement in response time for both client application responses (performance improvement) as well as a reduction in the overhead of system resources (CPU, Memory, Disc, Network) or back-end systems. Performance improvement and decreasing load is the measure of success that Weben application aims. This measure is directly proportional to the cache hit rate (Cache Hit Rate) of the queried data as it is in all cache systems. One of the issues that needs to be solved with Weben is eviction. Removing data from cache because of the lifetime is over is called eviction. The data placed on the cache has a lifetime and should be deleted from the cache when its timeliness and validity are lost. Otherwise, both data lost its timeliness and validity is returned to the querying client application and also causes unnecessary data stacking on the cache.
