In SWF, what does the domain represent?

In Simple Workflow Service (SWF), the domain acts as a namespace that is used to organize workflows. This organizational structure allows developers to manage and categorize workflows conveniently within the service. By utilizing domains, users can create separate spaces to differentiate workflows that may have the same name but belong to different applications or environments. It helps in maintaining clear boundaries and minimizing conflicts between workflows, thus enhancing manageability.

Although domains do interact with various elements of the workflow, such as worker tasks and execution environments, their primary role is to serve as a mechanism for organizing and segregating workflows logically. This is essential for scaling applications and ensuring that workflows can be called and executed in an orderly manner.
