When to use Amazon SWF


Here are some scenarios where SWF can be used:

  • When you have multiple tasks that need to be coordinated and executed in a specific sequence based on some dependency or in parallel

  • When you have a distributed application and you need to coordinate and process tasks in a distributed application environment
  • When you need to execute ordered application steps
  • When you need to manage the application state during distributed execution
