Component Instance Scaling Policy Overview

After scaling policies are configured, instances can be automatically added or deleted based on resource changes or a specified schedule. This reduces manual resource adjustment to cope with service changes and service peak, helping you save resources and labor costs.

ServiceStage supports the following scaling policies:

• Manual scaling: Manually configure an instance scaling policy for a component. After the policy is configured, the number of component instances increases or decreases immediately.
• HPA: In Kubernetes, a HorizontalPodAutoscaler is a built-in component that provides horizontal pod autoscaling (HPA). It supports the application-level cooldown time window and scaling threshold functions based on the Kubernetes HPA.
