For a very small instance with only a couple of concurrent users a CDN might not make much difference. But if you take a look at your web server logs you’ll quickly notice that every post / like / vote triggers a storm of requests from other instances to yours, looking up lots of different things. It’s easy to imagine how quickly this would overwhelm an instance once it gets even a little busy.

One of the first web performance tools people reach for is to use a CDN, like Cloudflare. But how much difference will it make? In this video I show you my web server logs before and after and compare them.

Are you using s3 for storage or block storage? S3 is pretty cheap but I'm wondering if Cloudfront would still help me with the load on the ec2 instance when federation traffic is slamming it.

yes!

so the way this works is, you only pay for the lift from your EC2 instance to the s3 bucket, then cloudfront serves the bucket directly to public, which is far cheaper than EC2-> public

i dont think ive even triggered the non-free tier of cloudfront yet.
