We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

The most valuable feature is the stability. It's perfect in this way.The most valuable feature is the Queue Manager, which lies in the middle between our application and our core banking server.IBM MQ deals mainly with the queuing mechanism. It passes the data and it publishes it. These two abilities are the most valuable features.It also has a backup queue concept and topics, features that I have not seen anywhere else. I like these features very much.Secure, safe, and very fast.I like the architecture it provides seamlessly for assured delivery.The clusterization which results in persistence is the most valuable feature.The reliability of the queuing is the most valuable feature.

In the next release, I would like for there to be easier monitoring. The UI should be easier for non-technical users to set up appliances and servers.The memory management is very poor and it consumes too much memory.It is expensive. The cost is high. There should be more improvement in the new age of technologies.It could provide more monitoring tools and some improvement to the UI. I would also like to see more throughput in future versions.I wanted to upgrade Windows Server. It's not that easy to move.They have provided a Liberty Profile in the Web Console for administration, and that could be further enhanced. It is not fit for use by an enterprise. They have to get rid of their WebSphere process and develop a front-end on Node.js or the like.The initial setup is difficult. Creating your own cluster is difficult. Working with cluster repositories is difficult. Issue management with IBM MQ is difficult.I can't say pricing is good.

Their implementation is quite tricky. It's not that easy to implement RabbitMQ as a cluster.I was struggling with installing a few things. It would be good if was somewhat similar to RedHat. There should be more documentation regarding installation troubleshooting.RabbitMQ is clearly better supported on Linux than it is on Windows. There are idiosyncrasies in the Windows version that are not there on Linux.

The biggest difference is the number of platforms supported. I have never heard of RabbitMQ running on ZOS (mind you ZOS and not z/Linux).
The same way I don't know that the AS400 platform would support RabbitMQ. Also, I don't think RabbitMQ has the same ease of use and set up that IBM MQ has.

Next thing to consider is support. Think about how long it will take to get support for RabbitMQ and a Fix vs the time to get support from IBM. Finally and not the least, you will also want to compare the features (like assured delivery).
