IBM bills by the network interface, hundreds of dollars per months to get a dual bonded NIC for private and public transfer. If you use the bandwidth close to capacity all day long for he whole month, it ends up the same cost as you would pay on Amazon for transferring that amount of GB.
But, it needs to be open source. Otherwise I'd rather stick with AWS Cognito + Dynamo/AppSync, because primarily that I can depend that it'll be around in five years. Even if I believe FaunaDB cloud will around, I know I won't be able to convince my other stakeholders. But, if it's open source, I can always argue that if FaunaDB-as-a-service disapears, I can host it myself (as a last resort).

Hard to say their cloud "sucks" when they offer a solution featuring the very thing being complained about in regards to other cloud services. Or maybe IBM's cloud really is terrible, but it would be hard to know that as an outsider since you failed to provide any substantiating info. If you could expand upon your initial assertion, that would surely help the rest of us see your point and assist you in proving your case.
