Source: Introducing sole-tenant nodes for Google Compute Engine — when sharing isn’t an option from Google Cloud Platform
Today we are excited to announce beta availability of sole-tenant nodes on Google Compute Engine. Sole-tenant nodes are physical Compute Engine servers designed for your dedicated use. Normally, VM instances run on physical hosts that may be shared by many customers. With sole-tenant nodes, you have the host all to yourself.
You can launch instances using the same options you would use for regular compute instances, except on server capacity dedicated to you. You can launch instances of any shape (i.e., vCPU and memory). A placement algorithm automatically finds the optimal location to launch your instance across all your nodes. If you prefer more control, you can manually select the location upon which to launch your instances. Instances launched on sole-tenant nodes can take advantage of live migration to avoid downtime during proactive maintenance. Pricing remains simple–pay only for the nodes you use on a per-second basis with a one-minute minimum charge. Sustained use discounts automatically apply, as do any new or existing committed use discounts.
Sole-tenant nodes enable a number of valuable use cases:
- Compliance and regulation – Organizations with strict compliance and regulatory requirements can use sole-tenant nodes with VM placement to facilitate physical separation of their compute resources in the cloud.
- Isolation and utilization – Control instance placement directly via user-defined labels, or let Compute Engine automatically handle instance placement across nodes. You can also create and launch different machine types, or “shapes” on your nodes, in order to achieve the highest level of utilization.
It’s easy to get started with sole-tenant nodes. You can launch a VM onto a sole-tenant node from the Google Cloud SDK, as well as from the Compute Engine APIs (support for Google Cloud Console coming soon):
// CREATE A NODE TEMPLATE
gcloud beta compute sole-tenancy node-templates create mynodetemplate
--node-type n1-node-96-624 --region us-central1
// PROVISION A NODE GROUP OF SIZE TWO
gcloud beta compute sole-tenancy node-groups create mynodegroup
--node-template mynodetemplate --target-size 2 --zone us-central1-a
// CREATE INSTANCE WITH 4vCPUS AND 8GB OF MEMORY ON A NODE
gcloud beta compute instances create my-vm --node-group
mynodegroup --custom-cpu 4 --custom-memory 8 --zone us-central1-aFor guidance on manual placements and more, check out the documentation. Visit the pricing page to learn more about the offering, as well as regional availability.
