Amazon S3 Integration for WordPress
Stop slow websites! The Amazon S3 plugin allows you to place the downloadable products from your store in the Amazon S3 cloud instead of hosting on your own site.
Amazon provides a service called Simple Storage Service, or S3- great service for hosting and storing your files online, cheaply. With S3, you only pay for what you use, giving it the name "the elastic cloud". By storing your downloadable files in the cloud instead of on your site, you increase download speeds exponentially, as well as reducing the amount of storage needs on your own hosting.
Super simple to install, connects easily with your Amazon S3 account.
