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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"The biggest advantage of this solution is that it is very easy to learn, and very easy to build applications."
"The multi-approach and the multi-capabilities are valuable."
"Having the solution come from IBM you know you are receiving a product of quality in components and in the services, it is very good."
"My favorite feature is the XML-based DFDL mapping, which is a tool that allows you to graphically map legacy data formats to modern data formats."
"Before we implemented IBM to integrate with other external parties, we had buckets of applications to build, and maintenance was difficult, as was support, but right now, post-implementation of IBM ESB, we have a better structure, better teams in development and response to customers, and an application that is centrally managed and monitored."
"The Cloud Pak for Integration is a useful feature."
"One of the most valuable features is App Connect Enterprise makes it possible to deploy it in the OpenShift cluster, which is very good. Overall the solution is very flexible."
"IBM Integration Bus's best feature is integration."
"Straightforward development and deployment."
"Performance-wise, this solution is really good."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"Integration and mapping are easy, which is a major advantage."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"This is a very reliable and stable solution that is used for a very large number of transactions."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
 

Cons

"Performance can be an issue sometimes. The tool occasionally crashes due to memory-related problems. We've reported these issues to IBM, and they are actively working on improving the tooling experience."
"IBM Integration Bus can improve JSON Schema validations. We don't have any kind of nodes that can support that kind of validation. If we want to containerize it by means of the docker's containers in the clouds, we are not able to manage it very well."
"Sometimes migration takes too long."
"They should add connectors to banking applications and other specific industries."
"It would be beneficial for it to function more as an iPaaS, with the runtime available in the cloud, potentially on platforms like AWS, Azure, or Google Cloud."
"The solution doesn't have a standard testing framework that can be used for integration performance and other tests."
"I would like for them to make the training much easier."
"We have to stop the integration server to start the debugging process."
"The solution can add container engines such as docker."
"The images and size of the containers are too big and I think that they should be more lightweight."
"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."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"Stability and pricing are areas with shortcomings that need improvement."
"My biggest complaint about this product is the price."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"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

"IBM is expensive."
"It is not cheap. It has its cost. It is one of the high-cost solutions."
"The price is reasonable considering the features we receive."
"The solution requires a license and is very expensive here in India."
"I generally do not get involved in the licensing or pricing because I'm a hardcore technical guy, but I'm aware of the fact that IBM is highly expensive, so not everybody can afford it. All the products are licensed."
"The pricing of the solution is high."
"IBM Integration Bus is expensive."
"IBM Integration Bus is expensive."
"IBM products are generally more stable and have more features, but also come at a greater cost."
"This product is more expensive than competing products."
"The price is very high and it's the main reason that we are searching for alternatives."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The solution is expensive."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The solution is expensive."
