This topic describes how you are billed for Serverless workflow.

Pricing

When you use Serverless workflow, you pay only for what you use. You are charged based on the number of step transitions in your flow execution. For example:

  • 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 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 includes three branches, and each branch includes one task step for executing the branch. Therefore, the total number of step transitions is two, including one choice step transition and one task step transition.
