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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"In summary, I can recommend this product because it is easy and straightforward to learn and use."
"It aligns well with containerized environments, which increases its scalability and high availability."
"The most valuable features of the IBM Integration Bus are the flexibility to easily integrate with other solutions, such as SAP or any other vendors."
"I consider the solution to be one of the most stable in the market, in comparison with others such as Oracle and this assessment I maintain on an ongoing basis."
"It is very straightforward. It is very user-friendly integration."
"It has reduced the programming from one hundred percent down to ten or twenty percent."
"IBM Integration Bus has been effective in facilitating our messaging and service-oriented architecture (SOA) or bus architecture. So, we're already utilizing it to transform the data from the source it's sending. It converts the data from the format the source sends it into the format the destination system requires. So we are transforming the messages, which are required by the destination system; that's the one way."
"It makes the communication between multiple and heterogeneous applications so easy. We can bring together different messages and applications from different platforms and connect them through IBM Integration Bus."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"Integration and mapping are easy, which is a major advantage."
"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."
"Straightforward development and deployment."
"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."
"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."
 

Cons

"IBM doesn't really have a very strong community surrounding the product."
"The product lacks an integrated testing module."
"Its documentation is currently lacking. We have different environments where we use our configuration services, but we are not able to find documentation about how to deploy the local code to the server and how to set it up on a server level. I would like more documents from IBM that explain which variables should be in your machine while building a project, and when you deploy the code into the server, what should be their values. There are some variable values. I could not find such documentation. While working on a project, I developed the code on a local machine, and while deploying the code to our test environment, I made a couple of mistakes. We had to change some values at the server level, but we couldn't find any documentation regarding this, which made the task difficult."
"This reduction of two points doesn't mean that it is not as good as other products."
"IBM does not support orchestration, which is how they designed it, and other BPM tools in the market support orchestration. If they merged the BPM capability into this product, then it would be a better solution."
"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 IIB setup is still very command-based. The implementation is not so easy."
"We have to stop the integration server to start the debugging process."
"The solution can add container engines such as docker."
"Technical support is very slow and needs to be improved."
"I find the installation configuration is quite difficult compared to other solutions."
"Technical support is good but they could have a better response time."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"The product's features are not being upgraded or enhanced by the vendor"
"It is currently a weighty product."
"The images and size of the containers are too big and I think that they should be more lightweight."
 

Pricing and Cost Advice

"IBM Integration Bus solution is expensive and this is one of the reasons we are looking for an alternative, such as MuleSoft."
"It is not cheap. It has its cost. It is one of the high-cost solutions."
"The maintenance and support of the product are very 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."
"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."
"IBM Integration Bus is expensive."
"The price of this product could be lower."
"As customers, we always try to buy things as cheaply as possible. But the price for the IBM Integration Bus is fine. When we compare it to competitors, it's pretty much the same. However, there are a lot of open-source integration platforms coming to the market as well. So overall, the price is fine as far as licensed products are concerned."
"IBM products are generally more stable and have more features, but also come at a greater cost."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The solution is expensive."
"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."
"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."
