I have started using Amazon S3 to store many of the files my websites use. This cuts down the demand on my own server and, alongside the Cloudfront service, offers improved website performance.
When uploading your files to Amazon S3 make sure that you allow all users to have read access to the files. Otherwise, your website content won’t be displayed properly – you may see http 403 errors returned (suggesting that the file is not available without logging in).
You can make your files accessible by selecting each folder in your S3 bucket, right-clicking and selecting ‘Make Public’ option.
It’ll take a while if you have many website files, and please make sure that you only select this option for the files that you want everyone to be able to read.
