Initial Findings for Provisioning Variation in Cloud Computing

Cloud computing offers a paradigm shift in management of computing resources for large-scale applications. Using the Infrastructure-as-a-service (IaaS) cloud computing model, users today can request dynamically provisioned, virtualized resources such as CPU, memory, disk, and network access in the form of virtualized resources. The client typically requests resources based on computational needs and pays for resource instances based on their capacity and time utilized. Mapping these virtual resource requests to physical hardware could vary for identical requests. This can potentially cause variations in the performance of applications deployed on such resources. The performance of the application can vary according to the physical layout of the provisioned hardware (the number of Virtual Machines (VMs), the size/configuration of the VMs and the inter-VM locality).
