In this example we'll be using Node.js along with the Serverless framework to build our app. In this article, we'll take an in-depth look at the benefits of dynamic image resizing and walk you through using the Serverless Framework to resize your images dynamically with AWS Lambda. Serverless' auto-scaling, pay-per-execution functions not only let you avoid that massive collection of pre-scaled cloud data, but also significantly cut down on your compute costs, since you won't need to maintain a fleet of image scaling servers. Serverless Framework, which makes it very easy to build applications using AWS Lambda and other Serverless compute providers, is a great solution for this use case. And pre-scaling the original image to all imaginable sizes will result in an unsustainable hit to your cloud storage capacity and therefore to your monthly bill. But what's the ideal image size? Given the huge variety of potential screen sizes, that question is nearly impossible to answer. With those downsides in mind, it's in your interest to generate and serve a compressed image of lower but still good quality.

And finally, most visitors can't tell the difference between an original image and one with a data footprint 10 times smaller.

If the image download gets interrupted, they have to reload the entire page, eating into their data plan and causing frustration to boot. Then there's the fact that mobile visitors may well have a less-than-reliable network connection. But the lower-effort alternative, serving the full-size original image, doesn't scale.Ībove all, large images dramatically increase page load times, impacting the user experience and driving up bounce rates. Does your website or app contain images? Then you've probably had to deal with the problem of resizing those images for different page layouts and devices of all shapes and sizes, not all of them predictable.
