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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"The documentation, performance, stability and scalability of the tool are valuable."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"The transactions and message queuing are the most valuable features of the solution."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"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."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"It is a scalable solution...The setup is easy."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
"I like the user-friendly system and development of the service-oriented architecture."
"It's a consolidated product. It works and it does its job pretty well."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"The solution basically conforms to our standards."

Cons

"The installation configuration is quite difficult."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"The images and size of the containers are too big and I think that they should be more lightweight."
"I find the installation configuration is quite difficult compared to other solutions."
"The solution can add container engines such as docker."
"They are expensive and not worth the money we are spending on them."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"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."
"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."
"The server is very specific and it is very difficult to get experience with it."
"They should introduce better pricing for small companies."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"There are a lot of security settings that when you apply you have to re-apply again every time you modify a setting. It is something that really needs to be enhanced."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"There are a lot of security settings that when you apply you have to re-apply again every time you modify a setting."
