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

The most valuable features are the point to point messaging and the MQ API.It improves reliability and guarantees that messages are not lost.Reliable integration between MQ servers is the most valuable feature.Data integrity, reliability and security are valuable features that IBM MQ possesses.There is no dependency on the end party service's run status.We use queue managers/concentrators for message flow going upstream and downstream on applications with enterprise licenses.It runs everywhere, from the mainframe in the US to the PCs in the Gobi desert attached to an analog modem.Has helped integrate between applications, reduce rework, and costs by reusing working components of existing applications.

We have been able to set up a messaging system that facilitates data integration between the software modules that we sell.RabbitMQ will help to remove a lot of the complexities and create a loosely coupled codebase.I like the high throughput of 20K messages/sec, and that it supports multiple protocols.

I would like to see faster monitoring tools for this solution.I believe there is too much code to be done in order to handle the elements that you develop.I believe the stability of the product has decreased since we began using it initially.MQ needs instruments for connection with new modern queues like Kafka or RabbitMQ.SonicMQ CAA (continuous availability architecture) functionality on auto failover and data persistence should be made available without a shared drive, as it exists in multi-instance queue managers.It could get a face lift with a modern marketing campaign.the level of training as well as product marketing for this product are not that great. You rarely find a good training institute that provides training. Many of the architects in several organization are neither aware of the product nor interested in using it. IBM should provide good training on products like this.It needs a User Interface which is better than the aging MQ Explorer. The existing solution MQ Explorer is outdated.

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 next release should include some of the flexibility and features that Kafka offers.

Pricing and Cost Advice
To implement such an IBM solution, a company has to pay a lot in term of licensing and consultancy. A pricing model might be a better option.In terms of cost, IBM MQ is slightly on the higher side.IBM MQ appliance has pricing options, but they are costly.99.999 percent availability for less than a penny per message over the past 25 years. IBM MQ is the cheapest software in the IBM software portfolio, and it is one of the best.Pricing could be better, as with all IBM products. But their performance in production, along with security and scalability, will pay returns in the long run.I think the pricing is reasonable, especially with IIB as a part of it.

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).
