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

- New implementation uses nanoseconds. Due to that, the places where the Profiler is used as a Monitor and/or
a stopwatch will suffer with the difference in the return
- Also added a getDuration(), which returns the time in nanoseconds in case someone wants to use it instead
- Added an extra test to check if the getDuration() works fine with nanoseconds
- Fixed the test that checks the time in milliseconds: I added an error margin to cover the test better

Removing resource leaks from UsageSanityChecker and
refactoring it (encapsulation, removal of copy and paste, constants...)
Modularize static method for closing Statments in TransactionLegacy
and reusing this new method from other classes (Upgrade2214to30)
Create Unit and Integration Tests for UsageSanityChecker
Add DBUnit cases and integration profile for nitegration tests as
a base for future DB tests
Introduction of a new Transaction API that is more consistent with the style
of Spring's transaction managment. The existing Transaction class was renamed
to TransactionLegacy. All of the non-DAO code in the management server has been
updated to use the new Transaction API.
ACS is now comprised of a hierarchy of spring application contexts.
Each plugin can contribute configuration files to add to an existing
module or create it's own module.
Additionally, for the mgmt server, ACS custom AOP is no longer used
and instead we use Spring AOP to manage interceptors.
The managed context framework provides a simple way to add logic
to ACS at the various entry points of the system. As threads are
launched and ran listeners can be registered for onEntry or onLeave
of the managed context. This framework will be used specifically
to handle DB transaction checking and setting up the CallContext.
This framework is need to transition away from ACS custom AOP to
Spring AOP.
