I use TIBCO Enterprise Message Service for some of my internal communications. For instance, if there is an API called A that needs to communicate with an API referred to as B, we prefer to use messaging services, especially for synchronized communication. It facilitates efficient communication within our organization, so it's just valuable for communication processes.

We use TIBCO for external communication in the production environment. 

We use TIBCO Enterprise Message Service to connect different applications.

I have been developing solutions for five years using this product.
