To ensure continuous communication and data transfer, implementing a single MQTT gateway that can transparently redirect connections to multiple servers is crucial. The challenge lies in creating a system that allows clients to remain connected to a single address, such as 10.10.10.10:8888, while seamlessly switching to alternative servers in the event of a failure or maintenance. This necessitates a thoroughly designed load balancing strategy that can distribute incoming connections across multiple MQTT servers while maintaining message delivery consistency. To achieve this, we must utilize technologies such as MQTT protocol, load balancers, and network infrastructure. A well-designed solution should enable clients to publish messages to the gateway, which can then redirect them to available servers, ensuring uninterrupted communication. Notably, the use of upstream servers, as implemented through tools like Nginx, can sometimes lead to issues where clients may not receive confirmation for published messages. Aiming to resolve these limitations, our solution aims to provide a highly available, fault-tolerant, and scalable MQTT infrastructure that ensures seamless connectivity and message delivery for our clients
