https on S3 WITHOUT cloudfront possible?
We currently want to start hosting all our assets through AWS S3 and we also want to server everything over https. I understand I can use the Amazon Certificate Manager (ACM) with Cloudfront to server assets over https. The problem is that we are in the medical industry and we are legally prohibited to host anything outside the EU. With S3 I can choose a location (Frankfurt for us), but with Cloudfront I just get this option:
So I thought that I could maybe use Letsencrypt to generate my own certs. But I think I then still need to use ACM which only works with Cloudfront, which means I still can't use it.
Does anybody know if I can somehow setup S3 with https but without cloudfront?
Answer
Unfortunately you can't use an SSL certificate with your custom domain with S3. You can use the S3 domain with the Amazon SSL certificate like: https://my-example-bucket.s3-website-us-east-1.amazonaws.com.
If you want to use a custom domain with SSL, and you can't use CloudFront, then you will need to look into placing some other proxy in front of S3 like your own Nginx server or something.
