Since the function is central to the image CDN, we’ll start with that. This is when you’d want to look into an architecture that saves the optimized images to S3 as opposed to doing it inside the function. These would get optimized fine with this architecture.īut if your goal is to have a CloudFront image CDN that optimizes high resolution DSLR pictures, then this won’t be the right architecture for you. For example, WordPress creates smaller dimension version of images and those are almost always smaller than 1MB. In a lot of situations, this might be a non-issue. This means that we can’t have CloudFront optimize images that are larger than 1.33MB base encoded. Specifically, has a response limit of 1.33MB for base64 encoded response bodies. So once CloudFront optimizes the image in those 13 regional edge caches, it’ll have actually optimized the image across the entire CloudFront network.Īnother thing to keep in mind with this architecture is restrictions. That’s because there are only 13 regional edge cache locations where your function can run. This won’t really increase your costs compared to if you stored the optimized image on S3. This means that a function has to run multiple times to optimize an image. So our function will need to run once more to generate one. But, if someone requests the same image from London afterwards, CloudFront won’t have an optimized image saved there. So, for example, if someone requests an image from New York, our function will run and optimize there. This means that, when our function runs, it’s only optimizing the image for a specific CloudFront regional edge location. The first one is that CloudFront doesn’t save optimized images anywhere. Architectural tradeoffsĪs you can see, this architecture is quite simple, but comes with some tradeoffs. The response from the function then gets sent to CloudFront, which caches it. If the response is an image that it can optimize, it’ll do so. Our function kicks in when the origin returns a response. Otherwise, it forwards the request to the origin. If there’s a cache hit, it returns the cached response. That’s why we’re going to rely solely on a single function. With our image CDN, we want to keep the architecture as simple as possible. There are different ways to architect one, and each has some advantages and tradeoffs. So with this out of the way, let’s start by looking at the architecture of our image CDN.

So keep on reading if you want to learn how to set up an image optimizing CDN with CloudFront! How does an image CDN work? But it’s only using it as a CloudFront configuration example.Īs you’ll see then, there’s nothing WordPress specific about how to configure CloudFront. This article will use the CloudFront distribution from that guide. If you’re looking to know how to set up CloudFront with WordPress, there’s an in-depth guide for that already. You can use what you’ll see to create an image optimizing CDN for whatever use case you might need one for.
That said, I think it’s worth clarifying that this article isn’t about showing you how to configure CloudFront as an image optimizing CDN for WordPress only. Now, I’ve mentioned a WordPress a few times already. It’s actually quite simple to create a simple image optimization CDN with CloudFront using a function. But if you’re not using Ymir, you’re not without options either. Now, CloudFront doesn’t have an image optimizer product like Bunny CDN does. For example, Bunny CDN has an optimizer product that’ll do image optimization on the fly for you. They can do it seamlessly and require little to no integration with WordPress. That said, a lot of these plugins rely on (or try to upsell you) an image CDN to perform image optimization.Īn image CDN is generally a better way to optimize images.

But until that day, most of us install plugins that optimize images for us. There’s currently talk of adding webp conversion to WordPress. But, in most cases, it means converting images to the webp image format. As an example, this can mean converting gifs to pngs if they’re not animated. Page speed insight expects you to have optimized images. That said, if you’ve ever had to deal with getting a good page speed insight score for a client, you know page caching is just one of part of the equation! There are other things necessary to optimize the performance of a WordPress site. Using a content delivery network (CDN) is a great way to make your WordPress site fast for anyone on the planet. In a previous article, we looked at how you could use CloudFront to do WordPress page caching.
