Abstract
Dynamic provisioning of computing resources to fulfill the application requirement based on its current demand is one of the key challenges in cloud environment. However, availability of a resource to the application is not possible just by launching the VMs, but by the subsequent reconfiguration of the provisioned VMs, which is time-consuming and application dependent. In order to solve the instant resource provisioning problem, in this paper we propose to use some auto-scaling techniques based on prediction and proportional thresholding.
