What does this AWS Solution do?
The Serverless Image Handler solution combines highly available, trusted AWS services and the open source image processing suite Sharp to enable fast and cost-effective image manipulation on the AWS Cloud. The solution automatically deploys and configures a serverless architecture that is optimized for dynamic image manipulation, and uses Amazon CloudFront for global content delivery and Amazon Simple Storage Service (Amazon S3) for reliable and durable cloud storage at a low cost.
Version 4.1 of the solution uses the most up-to-date Node.js runtime. Version 4.0 uses the Node.js 8.10 runtime, which reaches end-of-life on December 31, 2019. To upgrade to version 4.1, you must deploy the solution as a new stack. For more information, see the deployment guide.
AWS Solution overview
AWS offers a simple solution that automatically deploys and configures a serverless architecture that is optimized for dynamic image manipulation. The diagram below presents the Serverless Image Handler architecture you can deploy in minutes using the solution's implementation guide and accompanying AWS CloudFormation template.
Serverless Image Handler architecture
AWS Lambda retrieves images from your Amazon Simple Storage Service (Amazon S3) bucket and uses Sharp to return a modified version of the image to the Amazon API Gateway. The solution generates a Amazon CloudFront domain name that provides cached access to the image handler API.
Additionally, the solution deploys an optional demo user interface where you can interact directly with your image handler API endpoint using image files that already exist in your account. The demo UI is deployed in an Amazon S3 bucket to allow customers to immediately start manipulating images with a simple web interface. CloudFront is used to restrict access to the solution’s website bucket contents.
