Management services are generally free of charge. This applies for the use of the Price Online Display (the displaying of costs when activating services), Cloud Eye (resource monitoring), Cloud Trace (monitoring of access to resources) and Heat/Resource Templates.
For management services that trigger follow-up activities (Distributed Messaging Service — DMS, Simple Message Notification — SMN), there are basic free contingents. Usage in excess of the basic free contingent incurs costs for the excess amount. This can include costs for network services.
