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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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 feature is the security."
"What I like best are the monitoring features."
"The system's stability is the most valuable feature."
"The message queue connectors are the most valuable feature. They have built-in connectors for most of the systems, like SAP and Oracle Database."
"We use IBM Integration Bus for document conversions."
"If people have good knowledge of it, they can really do a lot of stuff."
"I really like SQL integration nodes, HTTP nodes, event handling, event monitoring, the performance of the solution."
"The product is a user-customized tool so that you can adjust it to your specific needs pretty well with little trouble."
"Performance-wise, this solution is really good."
"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."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"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 features are the product's straightforward development and deployment, and its nice graphical user interface."
"It is a scalable solution...The setup is easy."
 

Cons

"The Toolkit itself is based on Eclipse and Java, and it does not respond sometimes."
"It is not scalable."
"The solution could improve by having built-in implementation and secure monitoring without the need for API Connect."
"The memory footprint should be minimized."
"Development toolkit (based on Eclipse) should be improved in terms of responsiveness."
"IBM doesn't really have a very strong community surrounding the product. Most of its direct competitors are open source solutions, and those have an excellent and well-developed community around the tech to help users navigate the ins and outs of the product. IBM is lacking in this area."
"The performance needs to be enhanced when working with the Toolkit."
"There are a couple of things I want improved, but I think they have already touched upon all those things in the most recent version. I'm not using the most recent version—I use a version older than the most recent—but I'm sure that if I looked into and explored it, I would see more support on the CI/CD and more support for unit testing automation. I've read that they released all these things in the new version of App Connect. Once I explore the new version of this tool, I'll probably have a better idea of suggested improvements."
"My biggest complaint about this product is the price."
"It is currently a weighty product."
"The solution can add container engines such as docker."
"Technical support is very slow and needs to be improved."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"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 images and size of the containers are too big and I think that they should be more lightweight."
"Technical support is good but they could have a better response time."
 

Pricing and Cost Advice

"The price of the license could be cheaper."
"IBM Integration Bus is expensive."
"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."
"The price is reasonable considering the features we receive."
"IBM Integration Bus is expensive. There are cheaper products in the marketplace."
"Our licensing is based on a five-year contract, and as far as I know, there are no costs in addition to the standard licensing fee."
"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."
"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."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"This product is more expensive than competing products."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"IBM products are generally more stable and have more features, but also come at a greater cost."
"The price is very high and it's the main reason that we are searching for alternatives."
"The solution is expensive."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The solution is expensive."
