QoS Class

The Quality of Service (QoS) Class is a classification system used by Kubernetes to organize Pods within the cluster into different classes and determine scheduling and eviction policies. When a Pod is created, its QoS Class is established based on the compute resources requests and limits specified. These classes are then utilized to determine scheduling and eviction decisions. Kubernetes has three QoS classes that a Pod can be assigned: Guaranteed, Burstable, or BestEffort.
