What is S3 storage?

The best way to think of this is a file, older-based storage, accessible to REST APIs, so it's not accessible through the normal disk read-write APIs. You cannot mount it as a disk. It is a great way to store large amounts of data, for example, if you're going to be bringing into your cluster or into your database. It's also a great way to store backup for a database and so on. The charges in here are based on the amount of storage actually
used, so there's no reservation for this storage. They start at $0.14/GB/month. There are also charges for data transfers, and we're dealing with data, we're always concerned about what will it cost for us to move the data into the cloud or get it out of the cloud when need be.
