Flavors define the compute, memory, and storage capacity of nova computing instances. To put it simply, a flavor is an available hardware configuration for a server. It defines the size of a virtual server that can be launched.
.. osdoc:: https://docs.openstack.org/nova/latest/user/flavors.html
.. sample:: Compute/v2/flavors/read.php
.. sample:: Compute/v2/flavors/list.php
Each iteration will return a :php:class:`Flavor` instance <OpenStack/Compute/v2/Models/Flavor.html>.
By default, only the id, links and name attributes are returned. To return all information
for a flavor, you must pass true as the last parameter, like so:
$flavors = $service->listFlavors([], null, true);
