How can MQTT replace VPN solutions?

This presentation compares Virtual Private Network (VPN) and Message Queuing Telemetry Transport (MQTT) technologies, highlighting the shift from VPN to MQTT. VPN has traditionally been used for secure network infrastructures and providing access to private networks, especially in enterprise environments. However, MQTT, a lightweight publish/subscribe messaging protocol, has become increasingly popular, especially in Internet of Things (IoT) applications. It offers advantages such as lower overhead, simpler management, and better performance in environments with many devices that need to exchange data in real-time. The presentation highlights the advantages of MQTT over VPN, such as scalability and efficiency in applications such as smart buildings, healthcare, and industrial automation. While VPN is still important for certain security applications, the trend shows that MQTT is becoming an increasingly important alternative for facilitating communication in distributed, real-time systems. The presentation provides insights into when and why MQTT could replace VPN.
