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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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 product helps efficiently work with different connectors from different back-end systems."
"The most valuable thing is the loose coupling and making the change in only one stack of the ESB layer or the middleware layer, which helps in big projects and when we have multiple channels calling back at the same time."
"IBM support is fantastic and quick."
"I am into microservices using Java Spring Boot, but if we are using legacy systems, IBM Integration Bus is very good for them, as they have their own computational logic called EC12 and their own proprietary language, and you can do any kind of complex logic and can implement other ESVs that I have seen."
"IBM ACE is very well engineered and very stable."
"We have benefited by using this solution from the IAB, we have been able to use different delivery types."
"IBM is much better; it has many more options and offers more functionality, and IBM offers better customization, configuration, and options in general."
"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."
"It is a scalable solution...The setup is easy."
"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."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"Performance-wise, this solution is really good."
 

Cons

"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."
"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."
"Sometimes migration takes too long."
"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."
"The user interface could be improved in a future release."
"The price could be better. It would also be better if they simplified the code."
"Documentation is not easy to understand."
"I would like for them to make the training much easier."
"My biggest complaint about this product is the price."
"Technical support is good but they could have a better response time."
"I find the installation configuration is quite difficult compared to other solutions."
"They are expensive and not worth the money we are spending on them."
"It is currently a weighty product."
"The solution can add container engines such as docker."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
 

Pricing and Cost Advice

"IBM Integration Bus is expensive. There are cheaper products in the marketplace."
"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 Integration Bus is expensive."
"The pricing of the solution is high."
"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."
"Pricing is on par with its competition."
"The pricing could be improved to make it more competitive."
"IBM Integration Bus solution is expensive and this is one of the reasons we are looking for an alternative, such as MuleSoft."
"The solution is expensive."
"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 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 products are generally more stable and have more features, but also come at a greater cost."
"The solution is expensive."
"This product is more expensive than competing products."
