Project objective

The goal of the project was to build a platform for the transmission of IoT information using the MQTT protocol. After analyzing current solution, RabbitMQ technology was chosen. During the architectural debates with the customer, requirements for the availability and speed of the given solution emerged.

Realization

The implementation took place by setting up the MQTT broker using automation installation scripts in Ansible. The individual steps included:

• MQTT persistence and load balancing design
• Installation and configuration of the test and production environment
• Verification of HA configuration and connection to F5 component
• Security of communication interfaces
• Exposure of the interface for administration
• Creation of performance tests and verification of required performance
• Monitoring setting using Zabbix
• Training, documentation and verification within the pilot operation
• Handing over to the customer for operation

Project result

The result is a platform that provides the required performance according to customer's wishes. At the same time, this platform can be easily installed in other environments or projects. The platform handles all operational processes, including backup and recovery.

A pleasant surprise was the usability of RabbitMQ for MQTT and at the same time, its high performance. When choosing a technology, some products came out more efficient in terms of performance, but in the end, the possibility of flexible configuration, good administration tools, the simplicity of monitoring with Zabbix and the use of protocols other than MQTT (for example AMQP) won out.
