Frequently Asked Questions
Cloud Infrastructure and Capacity
Do you support on-demand or non pre-emptible server types?
Yes. Cloudspace Server Pools can use either Spot instances or On-Demand instances.
Spot instance pricing is set via an open market auction. On-demand instance pricing is set to the average of the Spot market price for those instances in other leading cloud providers. In other words, On-demand instances in Rackspace Spot are priced at the Spot market price of other cloud providers.
Do you support GPU enabled hardware?
Yes, GPU enabled hardware is now available in Spot; including NVIDIA H100 and A30 GPUs.
Where should my critical data be stored?
We offer persistent volumes to store critical data.
We are also working on providing PostGres and MySQL Databases-as-a-service. If you'd like to get early access and provide feedback, we would love to hear from you.
Pricing and Billing
Will you charge my credit card when I enter it?
No. We charge your credit card at the end of each 30-day billing cycle or upon exceeding a certain bill threshold. A temporary authorization charge may be made to validate your payment card but is refunded within 72 hours.
When will I be billed?
Billing is in arrears, usually monthly; or on hitting certain bill thresholds. You are only billed on the actual usage of cloud resources via your Cloudspaces from the time those resources were made available to you.
If I spin up and tear down an environment, will I be charged?
We will determine the fractional hours of resources consumed, such as compute hours, persistent volume GiB-hours, load balancer hours, and bill you for the pro-rated amount (correct to the second), but subject to a minimum of 1 hour in a 30-day cycle. If you have used 0 and 1 hour of resources in a month, you will be billed for 1 hour.
Kubernetes Control Plane
Do you charge for the Kubernetes control plane?
We provide an easy to use, non-production (not highly available) control plane for free. This includes management for processes like etcd, kube-apiserver, kube-controller-manager, kube-scheduler, cloud-controller-manager, and other services. A highly available control plane that requires additional resources and management overhead is available as an optional add-on.
Is the Kubernetes control plane highly available?
By default, Cloudspaces use a non-production Kubernetes control plane that is not highly available. For production workloads, select the add-on that enables a production-grade, highly available control plane.
Does Cloudspace node pre-emption affect the Kubernetes control plane?
No, the Kubernetes control plane remains active and unaffected by node pre-emption. However, Cloudspaces that have lost all nodes will be automatically cleaned up after a 7-day period of inactivity.
