Horizontal Scaling

Horizontal scaling for the Kubernetes Cluster is represented via two implementations:

  • platform-managed horizontal scaling - allows adding/removing Kubernetes nodes. Based on your needs, you can configure scaling triggers to automate this process based on resource utilization.
  • Kubernetes-managed Horizontal Pod Autoscaler - scales deployments up/down based on observed CPU utilization

With both of these horizontal scaling methods, Kubernetes Cluster always has nodes available (when needed) and healthy application pods.

Tip

An extended real case example (WordPress) on the Kubernetes Cluster Scaling is provided within the linked article.
