US 2019/0317826 A1 · METHODS AND SYSTEMS FOR ESTIMATING TIME REMAINING AND RIGHT SIZING USABLE CAPACITIES OF RESOURCES OF A DISTRIBUTED COMPUTING SYSTEM

Abstract

Computational methods and systems that estimate time remaining and right size for usable capacities of resources used to run virtual objects of a distributed computing system are described. For each stream of metric data that represents usage of a resource of a distributed computing system, a model for forecasting metric data is determined and used to compute forecasted metric data in a forecast interval. A resource utilization metric is computed from the forecasted metric data and may be used to estimate a time remaining before the usable capacity of the resource is expected to be insufficient and the resource usable capacity is adjusted. The resource utilization metric may be used to determine the capacity remaining is insufficient. A right-size usable capacity for the resource is computed based on the resource utilization metric and the usable capacity of the resource is adjusted to at least the right-size usable capacity.

Dependent claims

A process stored in one or more data-storage devices and executed using one or more processors of a computer system to adjust usable capacity of a resource used by virtual objects of a distributed computing system, the process comprising:

computing two or more models for forecasting metric data based on a sequence of metric data that represent usage of the resource in a historical window;
selecting a model of the two or more models that corresponds to the sequence of metric data in the historical window;
computing forecasted metric data in a forecast interval using the model;
computing a resource utilization metric based on the forecasted metric data;
when the resource utilization metric is greater than the usable capacity of the resource, determining an estimated time remaining in the forecast internal that corresponds to an estimated time in the forecast interval when the usable capacity of the resource is expected to be insufficient;
and
adjusting the usable capacity of the resource used by the virtual objects when the resource is projected to have insufficient usable capacity in the forecast interval.
