Vertical Pod Autoscaler (VPA)

VPA automatically adjusts pod resource requests and limits.

Frequently Asked Questions

Frequently asked questions

What is the purpose of configuring stabilization windows and using appropriate scaling policies?

Configure stabilization windows, use app appropriate scaling policies, set reasonable min/max replicas, use multiple metrics for better decisions, implement cooldown periods, and monitor scaling behavior.

How does Cluster Autoscaling automatically manage resources?

Cluster autoscaling automatically adds or removes nodes based on pod scheduling needs. When pods can't be scheduled due to resource constraints, cluster autoscaler adds nodes. When nodes are underutilized, it removes them.

What techniques can be used to predict future load?

Use machine learning to predict future load based on historical patterns, implement scheduled scaling for known patterns (business hours, events), combine predictive and reactive scaling, and continuously refine predictions. Tools like KEDA support predictive scaling based on time-series analysis.

What are the key differences between Horizontal Pod Autoscaler (HPA) and Vertical Pod Autoscaler (VPA)?

HPA scales by changing replica count (horizontal). VPA scales by adjusting resource requests/limits (vertical). HPA is for handling increased load. VPA is for optimizing resource allocation.
