Redistributing workloads across worker nodes based on policy

Abstract:

Workload redistribution is provided. Upper and lower thresholds of resource utilization by worker nodes in a worker node group are defined. Hot and cold regions are determined in the worker node group to provide policy-based rescheduling of the worker nodes and redistribution of workload on the worker nodes based on the upper and lower thresholds of resource utilization. Resource utilization data corresponding to the worker nodes in the worker node group are collected at defined time intervals. It is determined whether an average resource utilization of any worker node in the worker node group is greater than the upper threshold of resource utilization based on the collected resource utilization data. In response to determining that the average resource utilization of any worker node in the worker node group is greater than the upper threshold, redistribution of the workload on the worker nodes is triggered.
