Cyclops: Rating-Charging-Billing
Solution for Cloud providers

Cyclops is a comprehensive dynamic rating-charging and billing solution for cloud services.
Designed for IaaS, as well as PaaS and SaaS.

Usage Data Records

UDR micro-service connects to cloud installation such as OpenStack, or CloudStack and autonomously collects the usage data. Harmonised data is being saved into a Time Series Based database and exposed through REST APIs.

Rating & Charging

Dynamic rates are generated through a rule engine by considering the various policies, environmental factors and pricing strategies. A charge for the usage made is calculated by using the harmonised data from UDR micro-service.


Various plans, discounts and coupons are considered through a billing engine to calculate the price to be paid by the user. Once the invoice is generated, the service connects to the payment gateway for payment fulfilment.


Data from the UDR, RC and Billing micro-services is presented to the end user in the form of charts, statistics and bills. Administrators can manage user accounts, select what meters are being used and configure the rating details.
