Credits are a virtual currency that can be used to purchase CloudBurst testing services, available from the Silk Performer Cloud Portal or your sales representative.
The billing process follows a pre-paid model: You first purchase Credits and then decide how and when you want to use them.
Credits must be purchased in advance.
Credits can be used for Virtual User license fees and for Cloud infrastructure (load-test agents) rental fees.
These are calculated based on the maximum number of concurrently active Virtual Users in a 24-hour testing period. The fee per active virtual user is dependent on the application type under test:
Virtual user cost protection: When your application doesn’t scale to meet the loads you anticipated, virtual user price protection means you only pay for what you have used.
The infrastructure rental fee is comprised of a passive and an active fee. The passive fee is charged for the time an agent runs, the active fee is only charged for the time the running agent is used to execute a load test. During the execution of a load test, both the passive and the active fee are charged.
Please contact supportline or your sales representative if you need more instances for your load-test.
