The described communication model where IoT devices initially connect with a remote server rather than communicating directly with a client is known as the Device-to-cloud model. In this scenario, the IoT devices send data to a cloud service for processing, storage, or further action. This centralization in the cloud allows for easier data management, analytics, and integration with other services.

The Device-to-cloud model is particularly beneficial for handling large volumes of data generated by IoT devices, enabling remote access and control, and providing a scalable architecture for numerous connected devices. The cloud acts as an intermediary that manages requests from clients and facilitates communications between devices and applications, allowing for more robust and flexible communication infrastructures.

This model contrasts with others such as Device-to-device, where devices communicate directly with one another, typically without involving a remote server; Cloud-to-cloud, which involves interactions between different cloud services; and Gateway-to-gateway, where data is exchanged between gateways rather than directly involving individual IoT devices and the cloud. Each of these other models has its own use cases and applications but do not follow the specific protocol of routing through a remote server as seen in the Device-to-cloud communication model.
