摘要:
A resource consumption of a resource compartment for a time interval is predicted. A resource entitlement for the resource compartment for the time interval is determined based on the predicted resource consumption.

A control system for controlling resource entitlement for a resource compartment in a resource-on-demand system includes nested loops. An inner loop includes an adaptive feedback control system including an adaptive controller operable to automatically determining a gain for the control system. The gain varies depending on a demand of the resource compartment in a previous interval, and the adaptive controller is operable to determine a resource entitlement for the resource compartment for a current interval based on the gain and a target utilization for the current interval. An outer loop includes a feedback control system operable to automatically determine the target utilization for the current interval, wherein the target utilization varies based on at least one QoS metric measured for the previous interval and a QoS metric target.

Embodiments of the present invention pertain to dynamically resizing a virtual machine container. According to one embodiment, an optimal utilization is determined based on a desired performance for a multi-tiered application and transaction mix information that describes a mix of transactions that result from executing the multi-tiered application. Automatic modification of an amount of a physical resource a virtual machine container is entitled to for executing a particular application component associated with the multi-tiered application is enabled where the amount is automatically modified based on the optimal utilization.
摘要:
A technique for controlling an output of a computing system having multiple adjustable inputs includes providing a set of adjustable inputs to the computing system, observing an output of the computing system while the system is in operation, and selecting a subset of adjustable inputs from the set of adjustable inputs based on the observation of the output. The inputs in the selected subset are then adjusted to achieve a desired output of the computing system.

A method for controlling resource allocation is provided. The method includes determining a service metric associated with a first application, wherein the first application is associated with one or more virtual machines. The method further includes comparing the service metric to an application specific service level goal associated with the first application and modifying a resource allocation associated with the first application at one or more of the virtual machines.
摘要:
A system for managing resources automatically among nodes includes a node controller configured to dynamically manage allocation of node resources to individual workloads, where each of the nodes is contained in one of a plurality of pods. The system also includes a pod controller configured to manage live migration of workloads between nodes within one of the plurality of pods, where the plurality of pods are contained in a pod set. The system further includes a pod set controller configured to manage capacity planning for the pods contained in the pod set. The node controller, the pod controller and the pod set controller are interfaced with each other to enable the controllers to meet common service policies in an automated manner. The node controller, the pod controller and the pod set controller are also interfaced with a common user interface to receive service policy information.

摘要:
A resource entitlement control system includes a controller, a model estimator, and a controller designer. The controller is operable to control an allocation of resources to a resource container. The model estimator is operable to calculate model parameters based on performance metrics and past resource allocations to the resource container, and the controller designer is operable to calculate one or more controller parameters based on the model parameters. The controller is also operable to calculate a control variable for controlling the allocation of resources to the resource container based on the controller parameters and the performance metrics.
