CloudFront

What is it?
AWS' CDN offering.
Why did we choose it?
For its integration with other AWS services (namely, Lightsail).
What do we use it for?
Contrary to what might be expected, we don't use CloudFront as a CDN in the normal sense of delivering static content like images and videos (we use BunnyCDN for that).
We use CloudFront as a first point of entry for users visiting Deserted Chateau. Rather than a user first reaching our load balancer, they instead first reach CloudFront, which sends on the request to the load balancer. This is for security reasons and AWS implementation reasons.
