- S3 has a [static website hosting option](http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteHosting.html) that is simply a setting that enables configurable HTTP index and error pages and [HTTP redirect support](http://docs.aws.amazon.com/AmazonS3/latest/dev/how-to-page-redirect.html) to [public content](http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteAccessPermissionsReqd.html) in S3. It’s a simple way to host static assets or a fully static website.
- Consider using CloudFront in front of most or all assets:
- Like any CDN, CloudFront improves performance significantly.
- 🔸SSL is only supported on the built-in amazonaws.com domain for S3. S3 supports serving these sites through a [custom domain](http://docs.aws.amazon.com/AmazonS3/latest/dev/website-hosting-custom-domain-walkthrough.html), but [not over SSL on a custom domain](http://stackoverflow.com/questions/11201316/how-to-configure-ssl-for-amazon-s3-bucket). However, [CloudFront allows you to serve a custom domain over https](http://docs.aws.amazon.com/acm/latest/userguide/gs-cf.html). Amazon provides free SNI SSL/TLS certificates via Amazon Certificate Manager. [SNI does not work on very outdated browsers/operating systems](https://en.wikipedia.org/wiki/Server_Name_Indication#Support). Alternatively, you can provide your own certificate to use on CloudFront to support all browsers/operating systems.

- 🔸If you are including resources across domains, such as fonts inside CSS files, you may need to [configure CORS](https://docs.aws.amazon.com/AmazonS3/latest/dev/cors.html) for the bucket serving those resources.
- Since pretty much everything is moving to SSL nowadays, and you likely want control over the domain, you probably want to set up CloudFront with your own certificate in front of S3 (and to ignore the [AWS example on this](http://docs.aws.amazon.com/AmazonS3/latest/dev/website-hosting-custom-domain-walkthrough.html) as it is non-SSL only).
- That said, if you do, you’ll need to think through invalidation or updates on CloudFront. You may wish to [include versions or hashes in filenames](https://abhishek-tiwari.com/post/CloudFront-design-patterns-and-best-practices) so invalidation is not necessary.

- 🚪CDNs are [a highly fragmented market](https://www.datanyze.com/market-share/cdn/). CloudFront has grown to be a leader, but many alternatives that might better suit specific needs.

- 🐥**HTTP/2** is [now supported](https://aws.amazon.com/about-aws/whats-new/2016/09/amazon-cloudfront-now-supports-http2/)! Clients [must support TLS 1.2 and SNI](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValuesSupportedHTTPVersions).
- While the most common use is for users to browse and download content (GET or HEAD methods) requests, CloudFront also supports ([since 2013](https://aws.amazon.com/blogs/aws/amazon-cloudfront-content-uploads-post-put-other-methods/)) uploaded data (POST, PUT, DELETE, OPTIONS, and PATCH).
- You must enable this by specifying the [allowed HTTP methods](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValuesAllowedHTTPMethods) when you create the distribution.
