Le Use-case Cn285 avec la solution de S.A.S. is a multi-cloud infrastructure management solution that offers several services based on recurring and variable pricing.

A daily statement allows to calculate the number of gigabits used by the servers of customers.
The pricing is based on the maximum amount of gigabits read by service and server in the period, here in monthly. services usage data are regularly reported to Cn285 thanks to Cn285 integration features. Cn285 then calculates the maximum number of GB used on the servers for each of the services.
The maximum amount that has been identified by Cn285 gives rise to the calculation of the usage fee through the service's pricing grid.

Fro example for :
  • from 0 to 128Gb : T1 €

  • from 128Gb to 256Gb : T2 €

  • from 256Gb to 512Gb : T3 €

So for a customer with a maximum monthly reading of 150Gb for a tariff of 128*T1€ + 22*T2€ = x€ for 150Gb.
