## Article

In part 4 of the thread about communicating with the cloud, I showed a simple method of talking to the cloud based on TCP protocol itself and character stream.

From the cloud side, such communication was handled in the application layer by the Telnet protocol . This method was appreciated by the blog readers, not without reason, it is so simple that it couldn’t be easier. But this is not the end of surprises regarding the methods of communication with the cloud. For dessert, I left the most spectacular method based on the MQTT protocol . It is a method supported by virtually all clouds, if one is not supported, it means that this cloud is not worth attention from the point of view of the IoT ecosystem . I invite you to travel through the MQTT in a practical aspect.
