Flavors are used to determine the CPU, memory, and storage size of the instance. OpenStack comes with a predefined set of flavors, with different sizes that range from tiny to extra large. For the cirros image, we will use the small flavor, which has 2 GB RAM, 1 vCPU, and 20 GB storage. Access to flavors doesn't have a standalone API client; rather, it's a part of the nova client.
You can see all available built-in flavors at OpenStack GUI | Admin | Flavors:
