MQTT
MQTT (Message Queuing Telemetry Transport) is a lightweight, publish-subscribe network protocol designed for constrained devices and low-bandwidth, high-latency, or unreliable networks. It is widely used in Internet of Things (IoT) applications to facilitate efficient communication between devices and servers, minimizing network bandwidth and device resource requirements. The protocol operates over TCP/IP and supports asynchronous messaging with a small code footprint.
Developers should learn MQTT when building IoT systems, real-time monitoring applications, or any scenario requiring efficient, low-overhead messaging between numerous devices, such as in smart homes, industrial automation, or mobile applications. It is particularly valuable for environments with limited network resources, as it reduces data transmission costs and power consumption, making it ideal for battery-powered sensors and remote deployments.
