Applications today can span on-site and off-site environments, as well as across multiple compute resources in the cloud. Come learn how to simplify your application’s state management, asynchronous tasks and work distribution with Amazon Simple Workflow (SWF). During this session, you will learn how to use the SWF Flow Framework to define your application logic in “workflows” that are managed at high-scale and with fault-tolerance by Amazon SWF.
