This topic describes the billing rules and billing method of CloudFlow.
Billing rules
When you use CloudFlow, you only pay for the resources that you use. You are charged based on the number of step transitions in your flow execution. Examples:
A parallel step has three branches, and each branch contains one task step. Therefore, the total number of step transitions is four, including one parallel step transition and three task step transitions.
A foreach step includes a task step, and the task step is executed four times in a loop. Therefore, the total number of step transitions is five, including one foreach step transition and four task step transitions.
A choice step has three branches, and each branch contains one task step. If one branch is executed, the total number of step transitions is two, including one choice step transition and one task step transition.
