The architecture is built on AWS Lambda and DynamoDB, along with a small Ruby Sinatra service to handle payments and access control.
After running it for a while and getting some limited feedback from potential users/customers, I ultimately abandoned the project due to an apparent lack of interest. For hobby projects, it's fairly easy to spin up a self-hosted data store for low volume needs (or use one of the other free services). For anything more than that, a business is probably going to spend the necessary time/money to maintain a full DBMS or use something like Firebase.
I might be missing an opportunity (I've had thoughts about resurrecting the project), but for the time being, I'm just not convinced there is enough demand on the paying side.
Maybe what we really need are more consumer-friendly, self-hosted (and secure) home VPN options. That way you can just run your services on the local network, and still have remote access without opening your devices to the world (or to other companies' servers). Until the average grandma can do that, the "personal cloud" idea will probably be overshadowed by manufacturers' desire to provide proprietary remote access options, because those go hand-in-hand with things like subscription pricing models, data mining, etc.
> Right now, the cloud - especially for IoT - isn't a healthy ecosystem. Your shiny new smart thermostat might as well be dialing into AOL on a dedicated landline. And unlike public services, these proprietary service providers lack long-term guarantees of service availability.
> What we need is a push for openness and interoperability in the cloud, and that will only happen if consumers demand it. The service providers are incentivized to do just the opposite.
