Building an image processor on AWS Lambda using The Serverless Framework

Good writeup on setting up an image processor using The Serverless Framework, a thing comparable to the aforementioned apex (and with an awfully generic and confusing name imho 😉).

1. When a user uploads a file an ObjectCreated event is produced and a Lambda function is invoked.
2. The Lambda function calls Amazon Rekognition to detect the faces and emotion of each face in the uploaded image.
3. The Lambda function processes the image and persists the image in Amazon S3

Here’s an example set of results:

The code of the Lambda function that calls Amazon Rekognition and processes uploaded images is available on GitHub.
