We have a guide that introduces you to the MQTT protocol. It is a lightweight publish and subscribe system where you can publish and receive messages as a client. An MQTT broker is primarily responsible for receiving all MQTT messages, filtering the messages, decide who is interested in each message and then, publishing the messages to all subscribed clients. There are several brokers you can use. It is easy to install, configure and use. You can also install Node-RED on the same cloud Digital Ocean hosting account to control and monitor your boards from anywhere in the world using your computer or your smartphone. To run your Cloud MQTT Mosquitto Broker, you need to use a hosting service that allows you to have access to the command line and install any software that you need. I recommend using Digital Ocean that offers an Ubuntu server that you can manage through a command line.

A number of devices and gadgets communicate in real-time using advanced wireless technologies. Smart cities, smart offices, smart homes, etc, are interconnected specifically by the IoT in which gadgets and smart objects communicate with each other using specific wireless protocols. IoT is also referred to as Ubiquitous Computing or Pervasive Computing, and there are many real-time applications of these technologies. The FASTags introduced in the country recently to pass through toll plazas is a classical implementation of IoT, in which a small chip on a vehicle communicates with the nearby sensor and a transaction is done automatically. In such scenarios, the scalability as well as reliability issues are addressed by high-performance network communications or advanced wireless communications using 4G, 5G and related technologies. Protocols and engines for the implementation of Internet of Things IoT helps smart gadgets communicate using less resources and minimum power consumption. In the IoT environment, MQTT is a specific protocol for low-powered and lightweight communication so that there is minimum load on devices and gadgets.
Perfectly configured and optimized message queues for IoT, ready in seconds.
As we provide a dedicated server, we do not have any restriction or limitations on the message throughput. We are using the different server configuration based on the plan you choose. The limitation is bound by the server limitations. You can choose to run the server with or without SSL Support. We have the provision to add your custom certificates as well. We run daily backups and store data to one of our back end servers. If you want we can send the daily backup to your Google Drive account. As we provide a dedicated server, we do not have any restriction or limitations on the Topic count, messages sizes and count.
Be sure to refer to the API documentation for full details about each method described in this section. See also the sample MQTT clients. Download an MQTT server certificate onto your device. Initiate a TLS handshake over mqtt.
