It's pretty fast and easy to setup. As for skills needed, anyone that can create a blog or download a torrent can figure it out.
Here's how to do it.
- Create an Amazon Account.
- Sign up for S3 and create your "buckets". Buckets are like folders on a server, but buckets live on many servers around the world.
- Sign up for Cloudfront, using your "Access Key ID". * Go to your Account and click on "Access Identifiers"
Next step is adding and removing files, right? We use Firefox Change-arounds. It works like FTP application and you can manage upload/delete your files.
