This brings me to their problem... Pricing! Their pricing (https://www.cloudboost.io/pricing) makes little to zero sense. First it is priced too low, a sign of future problems ahead. Second, I think they've got the entire model wrong. They should charge for bundles of API calls and GB of storage. Pay for what you use like cloud providers.
An example of pricing I would implement might look like $10 per GB of storage and $0.15 every 1k of API calls.
Thus a smallish example application that uses 2 GB of storage and makes 500,000 API calls a month would pay $95 / month.
