The AGPL does not prevent offering the software as a service. It's got a reputation as the GPL variant for an open-core business model, but it really isn't that.
Most companies trying to sell open-source software probably lose more business if the software ends up in the Debian/Ubuntu repository (and the packaging/system integration is not completely abysmal) than when some cloud provider starts offering it as a service.
