None of these are really Cloud Storage Normally I wouldn't reply to something like this but as someone who has built, runs a cloud storage service, and is building a "Next Gen." cloud storage service I feel like I have to in this case. I hate articles like this because services like Backblaze, Carbonite, Crashplan etc. are mentioned and throw in to the same pool as services like DropBox, FireFile.io and S3. Backblaze, Carbonite, Crashplan etc. are not cloud storage they are just back up services nothing more. iCloud is a confused middle man, its a half a backup service and half cloud storage with the photo iWork stuff it can do. Google Drive is about the same but is closer to a cloud storage service.
Proper cloud storage is something were the files always live in the "cloud", those files can be accessed through multiple different ways, across multiple devices at any time or the same time. Thats were services like WebDAV would come in so you could mount the storage as a remote disk and access the files directly from the cloud but none off that. DropBox is about as close as the avg. person can get to cloud storage but because of the syncing service it limits a few things that could make it even better. S3 can do a lot of the stuff and is cloud storage but because of the complexity it makes it out of reach of the avg. person. Amazon should never tell the user about Get and Put requests, telling me how much the rate for transfer is, if your in one DC its this amount if your in this DC its this other amount. Cloud storage is also suppose to be simple.

I agree, a cloud is different from a offsite backup solution. Cloud implies some work that is distributed. Offsite storage is just backup.
Unfortunately marketeers have hijacked the word "cloud" for their own purposes.

But Amazon is not really marketing S3 at end-users the way icloud, backblaze or dropbox do.
S3 is in a different market segment. It's a platform on which you can build a service offering.
If you are technically savvy enough you can use S3 'bareback'. Otherwise there are a bunch of services/software that use S3 as a backend and obfuscate all the nuances of pricing and api.
