• Instance - virtual machine (can be also called container, droplet and so on).
• Project - a named set of instances. Corresponds to the entire cloud or one of its regions (if supported).

• Volume - an external disk attached to a running instance.
• Flavor - a named combination of instance parameters such as number of CPUs, RAM, hard disk size and so one (can be also called instance type or droplet size).
• Network - a named set of IP addresses. An instance can obtain one or more addresses from this set.
