Helpful for complex integrations because it has tools and functionality to integrate with other systems
Everything needs to be improved. As far as integration and the cloud are concerned, things are moving to the cloud side. When you use Kubernetes and similar technologies, IBM Integration Bus doesn't greatly facilitate these environments. Maybe I don't know enough about that, but I feel that when it comes to the DevOps environment, the tool needs to be deployed on production in a way that's just like pods. Cloud integration needs to be more facilitated with the DevOps environment. This IBM technology needs to adapt because in the recent world, in the real world, we see that everything is just a cloud pod. Whenever you need to scale anything, you just put some cloud and pod and improve it, make any server and deploy it. But in IBM Integration Bus, there is a problem because we can't do this as easily. In short, IBM needs to more emphasize or more integrate with the cloud environments as well, similar to DevOps. There are limitations in IBM Integration Bus when it comes to DevOps.

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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"Facilitates communication between parties and legacy systems."
"The stability is mostly pretty good."
"The product is usually very easy to deploy."
"IBM Integration Bus has a complete set of tools that are implemented between rules when it comes to run time, but it's not easy to understand."
"I have found the inbound and outbound adapter confirmations valuable."
"REST API design and development support are useful. Building and exposing APIs using GUI API designer with editor makes implementation a breeze."
"I really like SQL integration nodes, HTTP nodes, event handling, event monitoring, the performance of the solution."
"The most valuable feature is that it's robust and its time to market is very short."
"Integration and mapping are easy, which is a major advantage."
"It is a scalable solution...The setup is easy."
"Straightforward development and deployment."
"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."
"The solution has good integration."
"Performance-wise, this solution is really good."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
 

Cons

"IBM could improve its connectivity."
"I would like to see more metered rest and API support. IBM is already working on it on Version 11, but it still needs improvement."
"The solution is complex and there is a need for more resources and greatly improved quality."
"I would like to be able to run and install this solution on different platforms."
"This product uses the PVU (Processor Value Unit) license model from IBM, and it is something that should be improved."
"IBM Integration Bus can improve by implementing no-code or drag-and-drop adapters development, similar to what is available in Red Hat."
"They should add connectors to banking applications and other specific industries."
"Its integration with Cloud Pak components could be better."
"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."
"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."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"Technical support is good but they could have a better response time."
"The installation configuration is quite difficult."
"Technical support is very slow and needs to be improved."
 

Pricing and Cost Advice

"The maintenance and support of the product are very expensive."
"Support costs are high compared to the competition. Otherwise, the support is good."
"The price is reasonable considering the features we receive."
"IBM provides a quite complicated licensing model."
"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 licensing model of IBM Integration Bus is good. It's a yearly subscription. However, the price is depending on the model that you choose. If it's a Cloud version, then you can pay per month or you can pay it annually upfront. There are three-year options available, but it depends on what deployment you have."
"For small companies, First of all, there are a lot of free products that could be used for integration. It can use the cloud or new implementation in the past. But if the tool is IBM, the official box in your company, you can make your submission and also publish the cloud to the work file. 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."
"It is a highly-priced solution."
"The solution is expensive."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"The price is very high and it's the main reason that we are searching for alternatives."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The solution 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."
