Research Interest

Professor Wong's research interests are in the areas of resource management in cloud computing and performance analysis of systems that support electric vehicles. Many organizations today are offering services over the Internet. Of interest is a scenario where an organization, referred to as a subscriber, acquires resources from an infrastructure provider to deploy its applications and pays for these resources on an as-needed basis. Such a strategy is attractive because the subscriber does not have to operate its own data center; it can also adjust the resource level as demand changes. From the subscriber’s perspective, it is desirable to acquire enough, but not an excessive amount of resources to provide an acceptable quality of service, which is measured by how well a given performance target is met. Queueing theoretic models are used to determine the resources required to meet a performance target based on response time. The accuracy of this model is evaluated using data obtained from running a web application on an experimental system. A PhD student, Ali Rajabi, is working on this topic under Professor Wong’s supervision.
