Amazon Simple Workflow Service (SWF) is a task-based API that makes it easy to coordinate work across distributed application components. It provides a programming model and infrastructure for coordinating distributed components and maintaining their execution state in a reliable way. Using Amazon SWF, we can focus on building the aspects of the application that differentiates it.

A workflow is a set of activities that carry out some objective, including logic that coordinates the activities to achieve the desired output.

Workflow history consists of complete and consistent record of each event that occurred since the workflow execution started. It is maintained by SWF.

Benefits of Amazon SWF

It enables applications to be stateless, because all information about a workflow execution is stored in its workflow history.
For each workflow execution, the history provides a record of which activities were scheduled, their current statuses and results. The workflow execution uses this information to determine the next steps.
The history provides steps in detail that can be used to monitor running workflow executions and verify completed workflow executions.
