Accounting/Billing Model Sample Clauses

Accounting/Billing Model. To allow the dynamic compensation to the customer and automatic subscrip- tion payment without the need of a TTP, the SC must hold funds to realize these transfers. Therefore, it is expected that the customer sends the subscription fee before the start of the service, and this fee is locked in the SC until the end of the SLA. Once the SLA is finished, the remaining funds are transferred to the SP. This is an unusual business model in cloud services; however, it can be found in “pre-paid” models and real estate renting models, where the customer pays in advance to rent a property for the subsequent period. The dynamic calculation of the compensation value works, inside the SC, as follows. Assuming that the monitoring solution will perform measurements every Pmonitoring minutes (the default value is 5 minutes), the sum of the time that the measurement was different than the agreed performance level (i.e., SLA violated) during the interval of compensation (Pcompensation) divided by the total expected measurements (Totalmeasurements) characterizes the period of violation (Pviolated), see Equation 1 and 2. This means that the SP was not delivering the defined performance level during Pviolated {α, Pviolated ∈ R | 0.0 ≥ α, Pviolated ≤ 1.0}
