1. A method comprising:

  • identifying demand for computing resources provided by multiple computing devices, wherein the multiple computing devices correspond to multiple servers located at one or more location;

    identifying operating states or modes for the computing devices based on the identified demand using a multivariable controller, the multivariable controller configured to determine how to alter multiple manipulated variables in order to create changes to multiple controlled variables;

    generating one or more models using historical data;

    correlating changes to the operating states or modes of the computing devices with changes in power consumption or with changes in response time, using the generated one or more models;

    generating a profile identifying a number of computing devices or processing units to operate in each of the operating states or modes;

    identifying one or more of the computing devices or processing units to undergo one or more state or mode changes based on the profile; and

    generating one or more control signals to trigger the one or more state or mode changes in the one or more computing devices or processing units,wherein the multiple manipulated variables include the operating states or modes of the computing devices; and

    wherein the multiple controlled variables include a power consumption of the computing devices and a response time of the computing devices.
