In this tutorial, we are going to walk you through how to complete a WordPress Amazon S3 integration as well as optionally using a content delivery network (CDN) alongside it. This can dramatically save you on bandwidth costs, act as a backup, and help speed up your site.
Amazon S3 is a storage solution, and part of Amazon Web Services many products. It is very similar to a web host, but generally offers less expensive bandwidth and storage. Typically this is used for large sites that either need additional backups or are serving up large files (downloads, software, videos, games).
Amazon has a proven track record of being very reliable, and because of their massive infrastructure, they are able to offer very low storage costs. Some of S3’s customers include Netflix, airbnb, SmugMug, Nasdaq, etc.
