On the contrary! We hope people will use the cloud for production, controlling your devices, relaying information, flashing updates, and much much more!
Certain things (streaming music, sending many hundreds or thousands of requests a minute, very low latency local communications (like remote controlling a car)) might not always be a great fit for the cloud however. You can still use the Core/Photon for these, but sometimes it’s best to work over the local network, or through your own server as well as the Cloud.
If you want to send lots of data quickly, or make lots of requests in a very short period of time, I would recommend using TCP / UDP sockets with whatever service you want to consume.
I hope that helps!
