Global vertical auto-scaling for application containers

A computer program product for global vertical auto-scaling for processing units, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by one or more processors, the program instructions executable to:

• periodically learn one or more functions, based on resource consumption metrics samples of processing units;
• use the one or more functions to obtain a predicted maximal resource consumption value per resource and a predicted minimal resource consumption value per resource for a processing unit;
• determine a global priority of the processing unit, wherein the global priority determines a rank of the processing unit in an order of precedence for getting resources;
• calculate a prioritized predicted consumption value per resource for the processing unit, based on the global priority, the predicted maximal resource consumption value, and the predicted minimal resource consumption value;
• extrapolate, from the prioritized predicted consumption value, a resource requirement value per resource and a resource consumption limit value per resource for the processing unit;
• and
• feed the resource requirement value and the resource consumption limit value to a processing unit management system.

A computer system for global vertical auto-scaling for processing units, the computer system comprising one or more processors, one or more computer readable tangible storage devices, and program instructions stored on at least one of the one or more computer readable tangible storage devices for execution by at least one of the one or more processors, the program instructions executable to:

• periodically learn one or more functions, based on resource consumption metrics samples of processing units;
• use the one or more functions to obtain a predicted maximal resource consumption value per resource and a predicted minimal resource consumption value per resource for a processing unit;
• determine a global priority of the processing unit, wherein the global priority determines a rank of the processing unit in an order of precedence for getting resources;
• calculate a prioritized predicted consumption value per resource for the processing unit, based on the global priority, the predicted maximal resource consumption value, and the predicted minimal resource consumption value;
• extrapolate, from the prioritized predicted consumption value, a resource requirement value per resource and a resource consumption limit value per resource for the processing unit;
• and
• feed the resource requirement value and the resource consumption limit value to a processing unit management system.
