Efficient data transformation and seamless integration drive successful deployments
As for improvements in IBM Integration Bus, we are getting another feature of the retry mechanism now. Version 8.13 was upgraded, and we started using the retry mechanism itself, and we are using nodes in the development level. They are improving one of the nodes such as the HTTP request node, implementing the indirect retry mechanism itself, and we are getting new features.

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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"IBM Integration Bus' most valuable features are its performance, fast and easy development, and easy support."
"The multi-approach and the multi-capabilities are valuable."
"I have found the inbound and outbound adapter confirmations valuable."
"Earlier, it was only possible to have an on-premises installation, but now that it's compatible with the cloud, it's a very seamless and fantastic tool."
"In summary, I can recommend this product because it is easy and straightforward to learn and use."
"There are three elements that make IBM Integration Bus very important for our organization's payroll systems which are the solution's high scalability, performance, and reliability."
"If people have good knowledge of it, they can really do a lot of stuff."
"The product helps efficiently work with different connectors from different back-end systems."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"The transactions and message queuing are the most valuable features of the solution."
"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."
"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."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
 

Cons

"IBM provides a quite complicated licensing model."
"Technical support is something that should be better."
"IBM does not support orchestration, which is how they designed it, and other BPM tools in the market support orchestration. If they merged the BPM capability into this product, then it would be a better solution."
"They need to come up with Integration Platform as a Service (iPaaS). It should also have a feature for integrating with those applications that are on the cloud."
"We used a third-party vendor, who help us install the solution and it was not easy."
"The product could be improved by including more resources on SQL and improving the simplicity of the resources available."
"Surely something that can be improved is session management. Sometimes sessions hang, and practically every day we hear about session congestion and this kind of thing."
"Its licensing or subscription model should be improved for more flexible adoption. There should also be more ease of use."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"My biggest complaint about this product is the price."
"Technical support is good but they could have a better response time."
"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."
"Stability and pricing are areas with shortcomings that need improvement."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."

"The price of this product could be lower."
"IBM is expensive."
"Pricing is on par with its competition."
"IBM Integration Bus is expensive."
"The pricing could be improved to make it more competitive."

"The price of the IBM Integration Bus is expensive. If you compare the price to the cloud version you can purchase what you need but the on-premise version price is flat."

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