If I have an EC2 instance, running a web app (HTTP), and I have an Amazon-provided SSL certificate, I can use CloudFront to make the EC2 instance accessible via HTTPS, handling the certificate automatically. Is this a legitimate use of CloudFront, or should this be done differently?

    did you try using an Application Load Balancer? depending on your use case perhaps CF is overkill Sep 19 at 17:17

    @OscarDeLeón I looked at ALB, however the base price seems pretty high for this particular instance - the ALB would cost about as much as the instance itself.

Yes using CloudFront is a legitimate way to enable https, and (as iBug pointed out in comments) can reduce your bandwidth egress costs a little. Another option is to use an application balancer, which integrates with AWS Certificate Manager (ACM) to enable https.

A lower cost method is to install a certificate directly on your EC2 instance using Lets Encrypt and some of their compatible software. You can't use an ACM certificate with just an EC2 instance. Certbot is a common piece of software used to request LE certs.

  • Thanks for these pointers, I will be checking out Lets Encrypt

  • Using CloudFront generally reduces your cost if the origin is an EC2 instance (or S3). EC2 and S3 charges a flat egress price while CloudFront charges "use more, pay less", and it even starts lower (8.5¢ for US / Canada vs EC2 9¢).

  • Thanks iBug I added your comment to the answer. AWS bandwidth is pretty expensive either way, for some sites I use an external caching CDN which can reduce costs more.
