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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."

"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."

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

"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."

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

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

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

"Straightforward development and deployment."

More IBM WebSphere Message Broker pros

"The customer service executives are very responsive."

"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."

"WSO2 Enterprise Integrator may cost you about twenty-five thousand dollars annually per year compared to IBM Cloud Pak, which would cost you around one million dollars."

"WSO2's analytics capability is good, considering the ELC support they provide."

"The built-in connectors help with quick connectivity to the platforms, and we are using this for both our banking and insurance clients."

More WSO2 Enterprise Integrator pros

Cons

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

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

"Technical support is good but they could have a better response time."

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

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

"The scalability is not strong. If you want to scale it you have to install multiple servers."

"The configuration of the product is not an easy task for everyone."

"The micro integrator should be improved. There is room for enhancement considering alternative integration components."

More WSO2 Enterprise Integrator cons
