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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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.

It allows you to deal with any mediation situation based on messages using concepts like proxy services and APIs.

The Data Services Server is a beautiful product which allows you to "expose" your data as REST and/or SOAP services secured or not using any of the databases you might to keep your business data. Using with the Identity server it gives you the possibility to manage all the identity subjects in your Organization, it connects out of the box to any corporate user store you have through LDAP or JDBC, it allows you to manage different mechanisms to implement authentication / authorization using Web SSO, SAML2, OAUTH2, federated authentication, among others. Also, it allows you to control all this through its administrative interface which could be exposed out of the box as SOAP services and also you can use it to implement role based access controls using XACML policies and business claims.

Quotes from Members

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

Pros

"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."

"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."

"Before the cloud, it was very easy for us to build and it was quick to integrate."

"It is a scalable solution...The setup is easy."

"The documentation, performance, stability and scalability of the tool are valuable."

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

"Performance-wise, this solution is really good."

"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."

More IBM WebSphere Message Broker pros

"The Enterprise Service Bus is really fast and flexible, it allows you to deal with any mediation situation based on messages using concepts like proxy services, APIs, and it has lots of connectors that facilitates its interaction with other products."

Cons

"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."

"I know that Message Broker was a very tightly copied product with another IBM product, that is, IBM MQ. I would like to have a little bit more decoupling from the IBM MQ because it should not be a prerequisite for IBM WebSphere Message Broker usage."

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

"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."

"Technical support is very slow and needs to be improved."

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

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

"It is currently a weighty product."

More IBM WebSphere Message Broker cons

"In a general sense, the documentation of these products should be improved."

Pricing and Cost Advice

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

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

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

"This product is more expensive than competing products."

"The solution is expensive."

"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"
