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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"It aligns well with containerized environments, which increases its scalability and high availability."
"If people have good knowledge of it, they can really do a lot of stuff."
"It is a stable solution."
"REST API design and development support are useful. Building and exposing APIs using GUI API designer with editor makes implementation a breeze."
"One of the most valuable features is how seamless and easy to use this solution is. This is a fantastic solution and a very measured product."
"I found all features valuable. There are a lot of connectors."
"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 message enrichment and message transformations are great features and the solution also has great security."
"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."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"Straightforward development and deployment."
"The transactions and message queuing are the most valuable features of the solution."
"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."
"The documentation, performance, stability and scalability of the tool are valuable."
 

Cons

"IBM doesn't really have a very strong community surrounding the product."
"Stability is mostly fine. However, integration with Oracle is not good."
"I don't mind the pricing."
"The product does not provide API management."
"I contacted technical support, but I wasn't able to get the correct answer. I feel I wasn't given a good response."
"This product uses the PVU (Processor Value Unit) license model from IBM, and it is something that should be improved."
"However, with the benefit of the insights we now have, if we were to do the same process again, over five years, WSO2 has done so well, and some other middleware is also doing well. Likely we would not choose IBM if we had to choose again."
"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 product's features are not being upgraded or enhanced by the vendor"
"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."
"Technical support is very slow and needs to be improved."
"I find the installation configuration is quite difficult compared to other solutions."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"My biggest complaint about this product is the price."
 

Pricing and Cost Advice

"The price is reasonable considering the features we receive."
"Pricing is on par with its competition."
"IBM Integration Bus is expensive."
"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."
"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 itself is prices fair but App-Connect is a bit expensive which we use in conjunction with it."
"The price of this product could be lower."
"IBM Integration Bus solution is expensive and this is one of the reasons we are looking for an alternative, such as MuleSoft."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The solution is expensive."
"This product is more expensive than competing products."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"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."
