Optimizing Client Latency in a Distributed System by Using the “Remote Facade” Design Pattern

In this paper we investigate the role of the Remote Façade pattern in the optimization of distributedsystems. The intent of this pattern is to wrap fine-grained remote objects in a coarsegrainedinterface and thus greatly reduce the total number of calls executed over the network. The measurement of the performance gain achieved by implementing this pattern is donethrough testing with a distributed application written in C# and using the latest Microsoftframework for distributed systems (Windows Communication Framework). Furthermore, wewill be presenting the scenarios in which the implementation of the Remote Façade patternbrings a significant performance gain. Finally we show further scenarios in which the performancebrought by this pattern can be investigated
