The conversation with Andy explores the origins and impact of MQTT, a powerful and transformative technology that enables information exchange. The conversation delves into the early days of MQTT, its role in bridging the gap between IT and OT, and the importance of a unified namespace and schema definitions. The flexibility of MQTT allows for payload agnosticism and the ability to send and receive data in various formats. The discussion also touches on the significance of MQTT Sparkplug in providing a common way to define schemas and enable self-announcing devices. Overall, MQTT has revolutionized data exchange and integration in various industries. MQTT, a lightweight messaging protocol, has stood the test of time and continues to find new use cases. It is widely used for IoT applications and has even been adopted by Facebook Messenger. MQTT's simplicity and ease of implementation make it popular for edge processing and AI applications. The future of MQTT lies in two-way communication, where sensors can subscribe to data and receive configuration updates. Additionally, MQTT has the potential to be used in space for mesh networks between microsats. MQTT's 25-year legacy and industry impact are a testament to its enduring relevance.
