SWF FAQ–> To coordinate the application execution across workers, you write a program called the decider in your choice of programming language. The separation of processing steps and their coordination makes it possible to manage your application in a controlled manner and give you the flexibility to deploy, run, scale and update them independently. You can choose to deploy workers and deciders either in the cloud (e.g. Amazon EC2 or Lambda) or on machines behind corporate firewalls.
