Sole-tenant node clusters

Dataproc clusters can be created on Compute Engine sole-tenant nodes . A sole-tenant node is a Compute Engine server that is dedicated to hosting your project's VMs only. Creating a Dataproc cluster on a sole tenant node keeps the cluster's VMs physically separate from VMs in other projects. The clusters function as standard Dataproc clusters, but with additional hardware isolation to address security and compliance concerns.

Dataproc sole-tenant node clusters are created in a user-specified sole-tenant node group . Each cluster's master, worker, and secondary worker instances will be created within this sole-tenant node group.

First steps

1. See Before you begin .

2. Create a sole-tenant node template .

3. Create a sole-tenant node group .

   • Use autoscaling node groups if you will create autoscaling clusters in the sole-tenant node group.

     Node group autoscaling recommendations:

     • Make sure the node group's max-nodes is sufficient for the maxInstances of clusters you will create in the sole-tenant node group.
     • Use the default or migrate-within-node-group node group maintenance policy; VMs may be unavailable for up to one hour with the restart-in-place policy.

Creating a sole-tenant cluster

• Before creating a sole-tenant cluster, see the sole-tenant node VM restrictions .

• If you create an autoscaling cluster in a sole-tenant node group, it is recommended that node group also use autoscaling (see Node group autoscaling recommendations ).
