After creating the AWS S3 static website it was time for securing the website for communication over the network using HTTPS. Because we don't want anybody spying on us.

ACM

I had to setup a certificate from ACM with the domain name www.komlalebu.com I registered from Route53.

Cloudfront

I had to setup the cloudfront distribution with requested custom SSL certificate, and also configure the alternate domain name

Then I had to configure the Cloudfront origin domain name to point to the S3 static URL endpoint. Paste everything excluding http://

S3 static website URL: http://blog.komlalebu.com.s3-website-us-east-1.amazonaws.com which we had previously configured.

Once it was done, I got my Cloudfront secure distribution URL.
Cloudfront Domain name: https://d1cs99***.cloudfront.net

Route53

I had to setup Route53 with an alias record with name www.komlalebu.com and the alias value pointing to the Cloudfront Domain name.

And it was done. The website is secure.
