Overview
Serverless Image Handler on AWS creates a serverless architecture to initiate cost-effective image processing in the AWS Cloud. The architecture combines AWS services with sharp, an open-source image processing software, and is optimized for dynamic image manipulation. You can use this AWS Solution to help you maintain high-quality images on your websites and mobile applications to drive user engagement.
Benefits
Deliver dynamic images at run-time based on your customer’s device.
Detect and blur inappropriate images using Amazon Rekognition.
Crop images using the facial recognition capabilities of Amazon Rekognition.
Interact directly with your image handler API endpoint using image files that already exist in your account with a simple web interface.
Save on storage costs via automated version control, eliminating multiple versions of images.
Technical details
You can automatically deploy this architecture using the implementation guide and the accompanying AWS CloudFormation template.
Step 1
The AWS CloudFormation template deploys an Amazon CloudFront distribution that provides a caching layer to reduce the cost of image processing and the latency of subsequent image delivery. The CloudFront domain name provides cached access to the image handler API.
Step 2
Amazon API Gateway provides endpoint resources and initiate the AWS Lambda function.
Step 3
A Lambda function that retrieves the image from your existing Amazon Simple Storage Service (Amazon S3) bucket, and uses sharp to return a modified version of the image to the API Gateway.
Step 4
An S3 bucket for log storage, separate from your customer-created S3 bucket for storing images. If selected, the solution deploys an S3 bucket for storing the optional demo UI.
Step 5
If you activate the image URL signature feature, the Lambda function retrieves the secret value from your existing AWS Secrets Manager secret to validate the signature.
Step 6
If you use the smart crop or content moderation features, the Lambda function calls Amazon Rekognition to analyze your image and returns the results.
