Build workflows for Amazon Forecast with AWS Step Functions

This post shows how to create a Step Functions workflow for Forecast using AWS SDK service integrations, which allows you to use over 200 with AWS API actions. It shows two patterns for handling asynchronous tasks. The first pattern queries the describe-* API repeatedly and the second pattern uses the “Retry” option. This simplifies the development of workflows because in many cases they can replace Lambda functions.

Building a difference checker with Amazon S3 and AWS Lambda

This blog post shows how to create a scalable difference checking tool for objects stored in S3 buckets. The Lambda function is invoked when S3 writes new versions of an object to the bucket. This example also shows how to remove earlier versions of object and define a set number of versions to retain.
