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.

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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

Quotes from Members

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

Pros

"The most valuable thing is the loose coupling and making the change in only one stack of the ESB layer or the middleware layer, which helps in big projects and when we have multiple channels calling back at the same time."
"The solution addresses all of our middleware needs in respect of transformation, parsing, security and stability; everything really."
"The solution is stable and can scale relatively easily."
"The integration with other tools is excellent. It integrates well with batch issues."
"The most valuable feature is that it's robust and its time to market is very short."
"It's stable across multiple platforms and across multiple applications."
"The product helps efficiently work with different connectors from different back-end systems."
"It allows us to avoid the need for consumers to understand multiple API protocols and security arrangements, and in some circumstances can reduce the impact of systems being unavailable."
"Performance-wise, this solution is really good."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
"Integration and mapping are easy, which is a major advantage."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"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 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."
 

Cons

"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."
"Its licensing or subscription model should be improved for more flexible adoption. There should also be more ease of use."
"IBM Integration Bus could be easier to manage, but this is true of all vendors. It doesn't always do what it says on the box."
"We used a third-party vendor, who help us install the solution and it was not easy."
"The product lacks an integrated testing module."
"Migrating to this solution is complex and it would be helpful if they had a way to convert existing integrations."
"IBM Integration Bus isn't particularly user-friendly and has a big learning curve."
"I can't say that there is any improvement I’m looking for. I’m new and haven’t connected with all features. For all drawbacks that were in the old version, I think they have been solved. The scalability needs improvement."
"The product's features are not being upgraded or enhanced by the vendor"
"Stability and pricing are areas with shortcomings that need improvement."
"It is currently a weighty product."
"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."
"I find the installation configuration is quite difficult compared to other solutions."
"My biggest complaint about this product is the price."
"They are expensive and not worth the money we are spending on them."

But let’s say, if you are working with premises, then you have to buy a reasonable main full support and gain experience with your product."
