Specifying resource limits and configuring autoscaling

As a container orchestrator, Kubernetes comes out of the box with two important features that help to manage your cluster resources:

• Resource requests and limits for Pod containers
• HPA, which allows automatic scaling of your Deployments or StatefulSets based on CPU resource usage (stable support), memory resource usage (beta support), or custom metrics (also beta support)
