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

"The solution offers good performance and is stable."
"The solution's features are all quite useful. We use all of them."
"The system's stability is the most valuable feature."
"Having the solution come from IBM you know you are receiving a product of quality in components and in the services, it is very good."
"The message queue feature is very valuable."
"The product helps efficiently work with different connectors from different back-end systems."
"The most valuable feature is the security."
"It aligns well with containerized environments, which increases its scalability and high availability."
"The process-oriented solution allows you to define choreography and orchestration."
"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."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
"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."
"Millions of people were connecting every month on the system and there were no issues."
 

Cons

"The resources about IBM are hard to find, and it is not enough material."
"I would like for them to make the training much easier."
"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."
"The solution doesn't have a standard testing framework that can be used for integration performance and other tests."
"The cloud deployment of the IBM Integration Bus should be made easier."
"I would not say that IBM Integration Bus is not a good product, I would point out that it is limited to its own infrastructure."
"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."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"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

"The price of this product could be lower."
"The solution requires a license and is very expensive here in India."
"IBM is expensive."
"IBM Integration Bus is expensive. There are cheaper products in the marketplace."
"It is not cheap. It has its cost. It is one of the high-cost solutions."
"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."
"The pricing could be improved to make it more competitive."
"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."
"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."
