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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

Effective data transformation and integration in complex environments with high functionality
Something that could be improved in WSO2 Enterprise Integrator is that the problem is not a lack of capability or functionalities. The problem is that it is a very complex environment. To put your hand on this environment is a very demanding task. This is the real problem. The problem is not about the product, but about the complexity to manage, to configure, to decide what to do. I have some experience using SAP R/3. It seems to me something similar. When you have to configure a situation with a client, especially for a client not in an industrial sector, but in a service sector, it is quite usual that you are in trouble for some reason. This is always the story that I found in the implementations I have done. Maybe there are only three or four big problems, in some other cases there are more than that, but this is the situation usually. For WSO2 Enterprise Integrator, not the same, but I must say it is quite often there is a need to put together some pieces and make it work in a coordinated way.

Quotes from Members

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

Pros

"Before the cloud, it was very easy for us to build and it was quick to integrate."
"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."
"Performance-wise, this solution is really good."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"This is a very reliable and stable solution that is used for a very large number of transactions."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"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's technical support is very knowledgeable."
"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."
"The learning curve for this solution is very good."

Cons

"The installation configuration is quite difficult."

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

"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."

"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."

"I would like to see better documentation for the open-source version."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"They should introduce better pricing for small companies."
"The product's price is an area of concern where improvements are required."
"The server is very specific and it is very difficult to get experience with it."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"The setup can be difficult for those not familiar with the solution."
"The server is very specific and it is very difficult to get experience with it."
 

Pricing and Cost Advice

"This product is more expensive than competing products."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
