Building Workflows with AWS Step Functions
AWS Step Functions use a state machine to represent the workflow. A workflow consists of a set of tasks, each of which represents a discrete activity to be performed. Each task is defined by a state of the state machine. In this article, we will learn about the main concepts of AWS Step Functions and apply those to build a workflow for a sample business process: Order Fulfillment.

Serverless Solution to Offload Polling for Asynchronous Operation Status Using Amazon S3
This article proposes a solution to redirect the polling part to the Amazon Simple Storage Service (S3) - a highly available, scalable, and secured object storage service managed by Amazon Web Services public cloud provider (AWS). It will present a serverless implementation using AWS Lambda functions, but this is not mandatory if you want to use S3.
