Server static HTML page from Lightsail object storage bucket

Hello.

As far as I know it is possible to publish using a Lightsail bucket and a CDN distribution.

There is also a similar method using S3 buckets and CloudFront.
In this case, unlike the Lightsail bucket, access can be controlled using the S3 bucket, so it is possible to block communication that does not go through CloudFront.
