HPA sets two parameters: the target utilization level and the minimum or maximum number of replicas allowed. When the utilization of a pod exceeds the target, HPA will automatically scale up the number of replicas to handle the increased load. Kubernetes’ default HPA is based on CPU utilization and desiredReplicas never go lower than 1, where CPU utilization cannot be zero for a running Pod.

It monitors the number of idle pods, or unscheduled pods sitting in the pending state, and uses that information to determine the appropriate cluster size. Horizontal Pod Autoscaling (HPA) adds more pods and replicas based on events like sustained CPU spikes.

Delete HPA object and store it somewhere temporarily. get currentReplicas. if currentReplicas > hpa max, set desired = hpa max. else if hpa min is specified and currentReplicas < hpa min, set desired = hpa min. else if currentReplicas = 0, set desired = 1. else use metrics to calculate desired.

HPA's native integration with Kubernetes makes it a straightforward choice, without the need for the more complex setup that KEDA might require. 3. Stateless Microservices Scenario: You're running a set of stateless microservices that handle tasks like authentication, logging, or caching.

May 16, 2020 · It requires the Kubernetes metrics-server. VPA and HPA should only be used simultaneously to manage a given workload if the HPA configuration does not use CPU or memory to determine scaling targets. VPA also has some other limitations and caveats. These autoscaling options demonstrate a small but powerful piece of the flexibility of Kubernetes. Introduction to Kubernetes Autoscaling Autoscaling, quite simply, is about smartly adjusting resources to meet demand.
