IoTHub and function Building hot and Cold Paths

Building cold and hot ways for information from IoT gadgets in Azure is an errand that ought to be incorporated into each IoT venture. Building the information stream from gadgets into a logical administration and reinforcement in Azure is both straightforward and powerful. How about we make a glance at the stride by-step usage for this errand IoTHub and function Building hot and Cold Paths

IoTHub

To create IotHub, check the official docs — create the IoTHub.

Device Emulators

Blob Storage

To create Blob storage, check the official docs on how to create storage.

Function App Service Plan

To create the function app service itself, check official docs on how to create a Function App.

Configuring Function App

After creating the App Service Plan for the Function App, we have to create a proper type of our function itself. We have to choose the right trigger for it.

Choose to create a new function with EventHub trigger: 

Run the function as it is to open log streaming and see what is going on.

Logs:

IoTHub and function Building hot and Cold Paths

Nice! We are receiving messages into our IoTHub, and from IoTHub, they are delivered into the Function App.

Configuring Route and Endpoint for Cold and Hot Path

Endpoint

Go to your IoTHub and add new Custom Endpoint. Even in the Free plan in IoTHub, you are able to create one additional custom endpoint, what is enough for our case.

Routes — after, add two new Routes.
