Lambda
I recently started working on a workflow for picking up files from S3, processing them, and writing the results to another S3 location. This is a common pattern in data processing pipelines and our team wanted to see whether we could do it using AWS serverless services. We were able to get it running via Lambda functions and event triggers published to an AWS EventHub. The entire workflow was fairly easy to stand up once we grasped how the various services worked together.
