Kubernetes Cluster: Horizontal Scaling
Horizontal scaling for the Kubernetes Cluster is represented via two implementations:
- Jelastic-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.
