Siteleaf supports publishing to Amazon’s Simple Storage Service. S3 is a low-cost, highly durable service for static file storage and websites.
S3 allows you to set up custom redirects and routing rules.
AWS currently offers a Free Tier which includes 5GB storage and 20,000 hits per month in your first year, for more see: http://aws.amazon.com/free/
Amazon S3 is not a content delivery network, meaning your files will be served from a single data center. If you have a large amount of world-wide traffic, you may want to serve your S3 content through a CDN like Amazon CloudFront.
