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.
MANUEL VALDIVIA - PeerSpot reviewer

Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.

Quotes from Members

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

Pros

"The solution has a variety of valuable features: the ESB characteristics are great, the transformation, protocol bridging and routing are great, the list of features on offer are both useful and actionable, and the cost is pretty cheap compared to what else is available in the market."
"The biggest advantage of this solution is that it is very easy to learn, and very easy to build applications."
"The solution addresses all of our middleware needs in respect of transformation, parsing, security and stability; everything really."
"The integration with other tools is excellent. It integrates well with batch issues."
"We have benefited by using this solution from the IAB, we have been able to use different delivery types."
"Content is easily infiltrated in the eclipse infrastructure."
"The message queue connectors are the most valuable feature. They have built-in connectors for most of the systems, like SAP and Oracle Database."
"Yes IIB help us to shape up our organization in service oriented architecture."
"Integration and mapping are easy, which is a major advantage."
"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."
"The most valuable feature of IBM WebSphere Message Broker is the ability to facilitate communication with legacy systems, offering a multitude of great capabilities. For example, if there is a mainframe system in place with a web service serving as the front end. In that case, the solution enables efficient protocol transformations to convert all request payloads into a format that the legacy systems can accept, rendering the integration and transformation processes seamless and highly effective."
"It is a scalable solution...The setup is easy."
"The documentation, performance, stability and scalability of the tool are valuable."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
 

Cons

"I was lacking these features in App Connect, but I heard that the latest version includes things like unit testing, automation features, all those things."
"I would like for them to make the training much easier."
"To scale virtically, is difficult."
"The solution itself is quite expensive for smaller companies because of a complex architecture setup if you just start."
"The solution is too expensive for smaller companies."
"The solution needs to simplify its documentation, such as the user and operation manuals, to make them even easier to understand."
"Session management can sometimes hand forcing server reboots."
"They could integrate AI technologies with the product. Additionally, ongoing developments and enhancements in integration technologies could be beneficial."
"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 solution can add container engines such as docker."
"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."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"It is currently a weighty product."
"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."
 

Pricing and Cost Advice
