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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"IBM Integration Bus's best feature is integration."
"The most valuable features of the IBM Integration Bus are flexibility. It's also an alternative for integrating it with other projects, which we are not ready at this time to do, such as switching to tunnels. The tunnels would be used with other partners to make sure everything is secured."
"If you want a platform that seamlessly integrates your different applications, IBM Integration Bus is for you."
"IBM is offering with the Integration Bus a very robust and stable solution."
"Promotes the reuse of developed resources to more efficiently consume resources."
"The stability is mostly pretty good."
"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."
"Content is easily infiltrated in the eclipse infrastructure."
"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."
"The process-oriented solution allows you to define choreography and orchestration."
"Millions of people were connecting every month on the system and there were no issues."
"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."
"One of our clients is a signature company and developed on a classic Java enterprise application using OpenESB, and in one year they saved £20,000,000 on development and maintenance."
"The core is very stable."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
 

Cons

"I contacted technical support, but I wasn't able to get the correct answer. I feel I wasn't given a good response."
"Performance can be an issue sometimes. The tool occasionally crashes due to memory-related problems. We've reported these issues to IBM, and they are actively working on improving the tooling experience."
"We decided to move away from IBM Integration Bus for IT technical refreshments."
"The solution requires a license and is very expensive here in India."
"IBM doesn't really have a very strong community surrounding the product."
"The solution itself is quite expensive for smaller companies because of a complex architecture setup if you just start."
"The technical support for this product is not very good."
"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 documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better."
 

Pricing and Cost Advice

"IBM Integration Bus is expensive. There are cheaper products in the marketplace."
"IBM provides a quite complicated licensing model."
"The price of the license could be cheaper."
"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 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."
"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."
"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."
"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."
"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
