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

"Easy to understand documentation with a huge list of examples and tutorials."
"IBM Integration Bus is almost perfect in terms of stability."
"In summary, I can recommend this product because it is easy and straightforward to learn and use."
"If people have good knowledge of it, they can really do a lot of stuff."
"like the API lead integration, which is more focused, and I also like real-time integration."
"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."
"The solution's features are all quite useful. We use all of them."
"I found all features valuable. There are a lot of connectors."
"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."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
"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 the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."
"Millions of people were connecting every month on the system and there were no issues."
"The process-oriented solution allows you to define choreography and orchestration."
"The core is very stable."
 

Cons

"I believe there is room for improvement in the pricing structure to make it more accessible."
"IBM provides a quite complicated licensing model."
"I think security should be more simplified."
"We used a third-party vendor, who help us install the solution and it was not easy."
"The monolithic architecture is an issue. Due to the fact that it's built on monolithic architecture, the solution is not very lightweight."
"The product could be improved by including more resources on SQL and improving the simplicity of the resources available."
"The Toolkit itself is based on Eclipse and Java, and it does not respond sometimes."
"I can't say that there is any improvement I’m looking for. I’m new and haven’t connected with all features. For all drawbacks that were in the old version, I think they have been solved. The scalability needs improvement."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"The documentation needs to be better."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"Cloud deployment is weak and needs to be improved."
"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."
 

Pricing and Cost Advice

"Support costs are high compared to the competition. Otherwise, the support is good."
"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."
"IBM Integration Bus is expensive."
"IBM Integration Bus is expensive. There are cheaper products in the marketplace."
"It is a highly-priced solution."
"IBM is expensive."
"The pricing could be improved to make it more competitive."
"IBM Integration Bus itself is prices fair but App-Connect is a bit expensive which we use in conjunction with it."
"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 Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
"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."
