US Patent RE48714 Managing application performance in virtualization systems

Methods, systems, and apparatus, including computer program products, for assuring application performance by matching the supply of resources (e.g., application resources, VM resources, or physical resources) with the fluctuating demand placed on the application. For example, the systems and methods disclosed herein can be used to ensure that the application is allocated sufficient resources when it is initially deployed to handle anticipated demand; dynamically alter the resources allocated to the application during operation by matching the resource requirements to the actual measured application demand; and predict future resource requirements based on planning assumptions related to future application demand.
