Chapter 4. Flavors for instances
An instance flavor is a resource template that specifies the virtual hardware profile for the instance. You select a flavor when you launch instances to specify the virtual resources to allocate to the instance. Flavors define the number of virtual CPUs, the amount of RAM, the size of the root disk, and the size of the virtual storage, including secondary ephemeral storage and swap disk, to create the instance with. You select the flavor from the set of available flavors defined for your project within the cloud.
