This topic describes the billing policies of Serverless workflow.

Billing policies

When you use Serverless workflow, you pay only 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 parallel 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 parallel foreach step transition and four task step transitions.
  • A choice step has three branches, and each branch includes one task step for executing the branch. Therefore, two step transitions are involved in the execution of a branch, including one choice step transition and one task step transition.
