It's an apples to oranges comparison. Maybe for the low-level tech, but certainly not what it's used for. There are lots of online backup services out there. Some of them publicly make it known they use Amazon S3 for storage. I'm sure there are some other companies, who own their hardware, like Backblaze, but didn't optimise their cost structure using custom builds.
