Simplify Serving Dynamic Image Sizes with AWS Serverless Technology
A simple, efficient, and cost-effective solution to manage images dynamically using the AWS Serverless Image Handler.
On-demand resizing
Delivery
Pay-per-use
Cost
Near zero
Ops overhead
The Challenge
The client needed to serve many different image sizes/crops across web and mobile without pre-generating and storing every variant, which was ballooning storage costs and slowing down releases.
Our Approach
- Deployed the AWS Serverless Image Handler backed by Lambda and CloudFront.
- Configured on-the-fly resizing, format conversion, and smart cropping driven by URL parameters.
- Set up caching rules at the CDN layer to avoid repeat compute for popular sizes.
- Wired up infrastructure as code so the stack could be replicated across environments.
The Outcome
The client now serves any image size on demand with a single source image, cutting storage costs and eliminating a whole class of build-time image processing jobs.
