Description

https://cwiki.apache.org/confluence/display/CLOUDSTACK/Quota+Service+-+FS

Quota service while allowing for scalability will make sure that the cloud is not exploited by attacks, careless use and program errors. To address this problem, we propose to employ a quota-enforcement service that allows resource usage within certain bounds as defined by policies and available quotas for various entities.
Quota service extends the functionality of usage server to provide a measurement for the resources used by the accounts and domains using a common unit referred to as cloud currency in this document. It can be configured to ensure that your usage won’t exceed the budget allocated to accounts/domain in cloud currency.
It will let user know how much of the cloud resources he is using. It will help the cloud admins, if they want, to ensure that a user does not go beyond his allocated quota. Per usage cycle if a account is found to be exceeding its quota then it is locked. Locking an account means that it will not be able to initiat
e a new resource allocation request, whether it is more storage or an additional ip. Needless to say quota service as well as any action on the account is configurable.
