I'm evaluating RabbitMQ for a new project and am curious about the licensing costs associated with its commercial offerings. While the open-source version is free under the Mozilla Public License 2.0, I'm considering the enterprise-grade version for its additional features and support.

Specifically, I'm interested in understanding the RabbitMQ licensing cost for the commercial version. Could anyone share insights or experiences regarding the pricing models, including factors that influence the cost such as deployment scale, support requirements, and any minimum core or node configurations?

Your input would be greatly appreciated.
