Executive SummaryUpdated on Mar 3, 2025

IBM WebSphere Message Broker and OpenESB compete in the enterprise application integration space. IBM WebSphere Message Broker has an advantage due to its robust support and structured pricing.

Features: IBM WebSphere Message Broker is recognized for its comprehensive integration capabilities, scalability, and reliability.

Offers large-sized business information processing with a time-saving setup and impressive stability

I primarily use two previews of the product for Dev and two for QA as part of the production process. Whatever tools our company is using, the cost of a license in IBM WebSphere Message Broker is about 80% of all these software or tools. The message routing capabilities satisfy workflow efficiency. The product supports message formats of XML, JSON, and SSID, which are around 24 KB to 50 KB in size. The solution supports communication protocols like STTP and TCP. Features like DataGraph need to be introduced in IBM WebSphere Message Broker. Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore. For the aforementioned version, our company professionals can solve the queries on their own without seeking support from IBM. During the installation of a prior version of IBM WebSphere Message Broker, sometimes I have to configure the failovers through the cluster, where issues arise, and I often seek help from the support team. The solution is being used by some medicine companies in our organization that receive sales orders from the EDR or JDE. I would not recommend the product to others as its becoming obsolete and they can rather choose a middleware solution from Amazon or Azure. But I would overall rate the product a nine out of ten.

Quotes from Members

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

Pros

"Integration and mapping are easy, which is a major advantage."

"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."

"This is a very reliable and stable solution that is used for a very large number of transactions."

"IBM WebSphere Message Broker is one of the best middleware solutions"

"Message Broker is valuable because most of the applications are using MQ. Even in my current engagement, the few applications which I audit to onboard the bank are using MQ."

"Setup is very easy; we had proper documentation for setup, so it didn't take much time, and setup takes a maximum of two or three hours and I can set up the complete application."

"The solution has good integration."

"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."

More IBM WebSphere Message Broker pros

"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."

"Millions of people were connecting every month on the system and there were no issues."

"The core is very stable."

"The process-oriented solution allows you to define choreography and orchestration."

"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."

"One of our clients is a signature company and developed on a classic Java enterprise application using OpenESB, and in one year they saved £20,000,000 on development and maintenance."

"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."

Cons

"They are expensive and not worth the money we are spending on them."

"The solution can add container engines such as docker."

"My biggest complaint about this product is the price."

"I find the installation configuration is quite difficult compared to other solutions."

"The images and size of the containers are too big and I think that they should be more lightweight."

"It is currently a weighty product."

"The product's features are not being upgraded or enhanced by the vendor"

"Stability and pricing are areas with shortcomings that need improvement."

More IBM WebSphere Message Broker cons

"The documentation needs to be better."

"The documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."

"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."

"The documentation needs to be better — maybe they could add more accurate tutorials."

"Regarding its management, a web console being able to synchronize distributed instances would be great."

"Cloud deployment is weak and needs to be improved."

Pricing and Cost Advice

"The solution is expensive."

"This product is more expensive than competing products."

"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."

"The solution is expensive."

"The licensing cost of IBM WebSphere Message Broker needs to be reduced"

"IBM products are generally more stable and have more features, but also come at a greater cost."

"The price is very high and it's the main reason that we are searching for alternatives."

"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."

"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."

"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."

"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
