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.
Changes from Github code review:
- Added marvin test for quota plugin API
- removed unused commented code
- debug messages in debug enabled check
- checks for nulls, fixed access to member variables and feature
- changes based on PR comments
- unit tests for UsageTypes
- unit tests for all Cmd classes
- unit tests for all service and manager impls
- try-catch-finally or try-with-resource in dao impls for failsafe db switching
- remove dead code
- add missing quota calculation case (regression fixed)
- replace tabs with spaces in pom.xmls
- quota: though default value for quota_calculated is 0, the usage server
makes it null while entering usage entries. Flipping the condition so
as to acocunt for that.
- quotatypes: fix NPE in quota type
- quota framework test fixes
- made statement period configurable
- changed default email templates to reflect the fact that exhausted quota may not result in a locked account
- added quotaUpdateCmd that refreshes quota balances and sends alerts and statements
- report quotaSummary command returns quota balance, quota usage and state for all account
- made UI framework changes to allow for text area input in edit views
- process usage entries that have greater than 0 usage
- orocess quota entries only if tariff is non zero
- if there are credit entries but no balance entry create a dummy balance entry
- remove any credit entries that are before the last balance entry
when displaying balance statement
- on a rerun the last balance is now getting added
