Compute Flavors

Overview

Compute Flavors are predefined configurations that determine the amount of CPU, RAM, and storage resources allocated to a virtual machine. Each Flavor offers a different combination of these resources, allowing users to select the appropriate one based on the performance needs of their applications.

pluscloud open uses the SCS standard for Flavor naming. This standard uses a combination of letters and numbers to describe the specifications of each Flavor. The first part of the name identifies the number of virtual CPUs (vCPUs) available in the Flavor, while the second part describes the amount of random access memory (RAM) available. The third part, if present, indicates the amount of disk space allocated for the instance. All Flavors following that standard are prefixed with “SCS-”.

Available Flavors

The following table shows the list of all public Compute Flavors:

* Note on the ‘Disk (GB)’ column:

The flavors without a disk size do not use a local root disk, they use instead a (cinder-) volume of self-selected size which the instance then will use as the root disk device.

The flavors with a defined root disk offer a real root disk, which is then also located locally on the same hypervisor as the instance. This can also be recognized by the letter ’s’ at the end of the flavor name. Additional details can be found here https://docs.plusserver.com/en/compute/pluscloudopen/reference/local-storage/

Deprecated Compute Flavors

As a certified Souvereing Cloud Stack, we implement the latest Compute Flavor specifications. Part of the lifecycle management is also to deprecate old Compute Flavors. The ‘os:deprecation’ property is used to indicate when a particular Compute Flavor is set for deprecation, signalling that it may be removed or phased out in the future. You can also find a note in the description field.

The following table shows deprecated Compute Flavors and their deprecation date.
