Jul 19, 2021 · Cluster Autoscaling (CA) manages the number of nodes in a cluster. 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. Best Practices for Kubernetes Autoscaling Make Sure that HPA and VPA Policies Don’t Clash.

Scaling Java applications in Kubernetes is a bit tricky. The HPA looks at system memory only and as pointed out, the JVM generally do not release commited heap space (at least not immediately). 1. Tune JVM Parameters so that the commited heap follows the used heap more closely.

Without the metrics server the HPA will not get the metrics. This is the snippet from Kubernetes documentation. " The HorizontalPodAutoscaler normally fetches metrics from a series of aggregated APIs (metrics.k8s.io, custom.metrics.k8s.io, and external.metrics.k8s.io).Scaling Java applications in Kubernetes is a bit tricky.
