What modern MQTT deployments need: Four takeaways from our Chariot 3.0 webinar
Industrial MQTT infrastructure is evolving, and organizations are looking for deployment options that are more flexible, easier to manage, and better suited for modern architectures.
In our recent webinar, From Deployment to Data: What’s New in Chariot 3.0 and Sparkplug V4, Cirrus Link CTO Wes Johnson and VP of Sales Engineering Nathan Davenport shared the latest enhancements to Chariot and provided an update on the future of Sparkplug.
If you missed the live session, here are four key takeaways.
1. Containerized deployments are here
One of the biggest announcements was native Docker support in Chariot 3.0. Organizations can now deploy Chariot in containerized environments while simplifying configuration, certificate management, and licensing. New floating and lease licensing options also make it easier to support dynamic deployments and air-gapped environments.
2. Better tools make troubleshooting easier
Nathan demonstrated several improvements designed to give engineers greater visibility into their MQTT infrastructure, including updates to the built-in MQTT Test Client and expanded Sparkplug visualization.
As he explained:
“There are many times where the best tool that I can have in a production environment when debugging issues is just a client that can consume messages on whatever topic I want.”
Combined with Chariot’s built-in Sparkplug awareness, these tools help teams monitor live message traffic, visualize connected assets, and troubleshoot issues more efficiently.
3. Modern deployment requires flexibility
Beyond containerization, Chariot 3.0 introduces improvements that make deployments more adaptable to different industrial environments, including updated licensing workflows, REST-based management, and modular capabilities such as the IoT Bridge for Snowflake.
4. Sparkplug V4 continues to evolve
Wes also shared an update on Sparkplug V4, highlighting planned enhancements including improved support for multiple host applications, greater flexibility for Unified Namespace (UNS) topic structures, formalized JSON support, and continued improvements to interoperability.
As Wes noted:
“We wanted to provide a common language for producers and consumers of data.”
The next version of Sparkplug is being shaped through community collaboration, with a continued focus on making industrial data easier to share across systems.
