To prevent system capacities from being exhausted without notification, you can set up quotas. Quotas are operational limits. For example, the number of gigabytes allowed for each tenant can be controlled so that cloud resources are optimized. Quotas are currently enforced at the tenant (or project) level, rather than by user. Using the command-line interface, you can manage quotas for the OpenStack Compute Service and the Block Storage Service. Typically, default values are changed because a tenant requires more than 10 volumes, or more than 1TB on a Compute node.
