Lightweight Messaging refers to communication protocols that are designed to be simple and efficient, allowing for quick data exchange between systems. These protocols often use minimal resources, making them ideal for environments with limited bandwidth or processing power. Examples include MQTT and AMQP, which are commonly used in Internet of Things (IoT) applications. The primary goal of Lightweight Messaging is to facilitate real-time communication while reducing overhead. This approach enables devices to send and receive messages with low latency, ensuring timely updates and interactions. As a result, it is widely adopted in scenarios where speed and efficiency are critical, such as in smart home systems and mobile applications.
