We implemented the solution 15 years ago but recently compared it with MuleSoft and TIBCO.

Though I did not evaluate other options before choosing IBM WebSphere Message Broker, we recently moved to App Connect.

We are looking at replacing our IBM solution with RabbitMQ. It is currently being used in part of our business and we are thinking about expanding it to the whole enterprise.

There is also the option of Kafka, although you really have to understand your use case before engaging with it.

We compare other options for our customers and we look at the pros and cons of each solution. Normally, customers decide based on their budget, the features, and the expected workload. In most cases, I recommend IBM.
