Preemptible and Spot Instances on QHub¶
A preemptible or spot VM is an instance that you can create and run at a much lower price than normal instances. Azure and GCP use the term preemptible, AWS uses the term spot, and Digital Ocean does not support these types of instances. However, the cloud provider might stop these instances if it requires access to those resources for other tasks. Preemptible instances are excess Cloud Provider’s capacity, so their availability varies with usage.
Google Cloud Platform¶
Preemptible instances can be defined via using the
in the QHub config file as following.
google_cloud_platform: project: project-name region: us-central1 zone: us-central1-c availability_zones: - us-central1-c kubernetes_version: 1.18.16-gke.502 node_groups: # ... preemptible-instance-group: preemptible: true instance: "e2-standard-8" min_nodes: 0 max_nodes: 10
