messaging - Can I use MQTT for my use case? -

-

so, have bunch of mobile devices (millions) , have backend system. needs/use case are:- 1. collect data devices , send backend. 2. send push messages backend system individual or groups of devices.

so, given scenario, make sense use mqtt communication between backend , devices? 1 of confusions, have in use case #1, devices publishers , system in backend subscribers, whereas use case #2, devices subscribers push messages , backend system publisher. possible? or thinking wrong way?

having worked on number of examples (e.g. mobile telemetry system push notification) fit usage pattern can mqtt can fit perfectly. mqtt client can act both publisher , consumer, there no distinction.

you need design topic structure suit data sending in either direction, should not difficult.
