IoT and Event Streaming at Scale with Kafka & MQTT

This post details the integration of IoT devices with Apache Kafka and its ecosystem, specifically focusing on the use of MQTT. It outlines common IoT use cases and the challenges of integrating edge devices with enterprise systems. The post presents three Kafka-native options for MQTT integration: Kafka Connect source/sink connectors, Confluent MQTT Proxy, and Confluent REST Proxy. It highlights the pros and cons of MQTT and Kafka individually, and explains how their combination addresses the limitations of each for building scalable, reliable, and secure IoT infrastructures. The post emphasizes the role of Kafka Connect in pulling data from MQTT brokers at its own pace and the benefits of Kafka's stream processing, long-term storage, and enterprise integration capabilities for IoT data.
