Serverless Kubernetes in the cloud

All the major cloud providers now support serverless long-running services for Kubernetes. Microsoft Azure was the first to offer it. Kubernetes interacts with nodes via the kubelet. The basic idea of serverless infrastructure is that instead of provisioning actual nodes (physical or VMs) a virtual node is created in some fashion. Different cloud providers use different solutions to accomplish this goal.

Don’t forget the cluster auto scaler

Before jumping into cloud provider-specific solutions make sure to check out the Kubernetes-native option of the cluster autoscaler. The cluster autoscaler scales the nodes in your cluster and doesn’t suffer from the limitations of some of the other solutions. All the Kubernetes scheduling and control mechanisms work out of the box with the cluster autoscaler because it just automates adding and removing regular nodes from your cluster.
