@Serverless Land It was said each user id is used to subscribe to users own topic , so which component creates this topic after user is logged in ? this dynamic topic should be created and destroyed so that thousands of topics are not kept after being used . this is an amazing idea by the way need some more insights into this

[@ServerlessLand]

The subscription is made by the front end appliction upon login, Once the session is closed (browser shut) the subscription ends. this is all handled by IoT core.

@@ServerlessLand Thanks . so subscription will end with browser but the dedicated user topics would be created when users are created right ? so each user has a topic living as long as user is in the system ? any training videos you can point to for this subject

[@estebanuo]

Thanks. Why using MQTT (IoT core meeant to be for IoT...), when it could be used directly WebSockets for web applications?

[@ServerlessLand]

Using IoT core in this way allows us to fan out to multiple connections (devices) without having to create and manage additional endpoints.
