Managing Projects and Users

An OpenStack cloud does not have much value without users. This chapter covers topics that relate to managing users, projects, and quotas. This chapter describes users and projects as described by version 2 of the OpenStack Identity API.

Projects or Tenants?

In OpenStack user interfaces and documentation, a group of users is referred to as a project or tenant. These terms are interchangeable.

The initial implementation of OpenStack Compute had its own authentication system and used the term project. When authentication moved into the OpenStack Identity (keystone) project, it used the term tenant to refer to a group of users. Because of this legacy, some of the OpenStack tools refer to projects and some refer to tenants.

Tip

This guide uses the term project, unless an example shows interaction with a tool that uses the term tenant.
