Organisations looking to build and offer Cloud services on Apache CloudStack need to be able to either monetize their offerings and charge for usage or monitor and report on their Cloud's consumption. Majority of such organisations already have existing billing or business support systems and do not require an integrated billing or reporting system, provided the usage data can be exported from CloudStack in a standard and structured format such as XML, JSON, or CSV. Tariq Iqbal of ShapeBlue provides an overview of the Apache CloudStack Usage Metrics, Usage Server and the multitude of ways for accessing the Usage Data for billing and reporting purposes, including real world use cases of some of the integration projects he has worked on.
