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 biggest advantage of this solution is that it is very easy to learn, and very easy to build applications."
"The message queue, like, message queue connectors. Then they have a built in connectors for most of the systems, like SAP, oracle database, and this Civil connector is there. Of course, we have this SQL database connector So those built in connectors are there. For the almost most of the systems, we have built in connectors. And second thing is that it is a stateless Integration, so it doesn't maintain a state of the integration. Bus the Stitches Integration makes it very fast."
"It can be implemented as an enterprise service bus to seamlessly connect all applications within your enterprise."
"Promotes the reuse of developed resources to more efficiently consume resources."
"I use the integration of Kafka and the message flow, which is really good. It is also good for moving any file from one location to another. Using IBM Integration Bus in the data stage is pretty simple. You can see the preview and other things. The MQ server integrated with IBM Integration Bus is really great. I don't have to do a lot of configuration from that side. It is really good."
"The most valuable feature is that it's robust and its time to market is very short."
"The most valuable feature is that it is clear and easy to learn."
"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."
"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."
"The core is very stable."
"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."
 

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."
"In terms of improvement, the UI should be more user-friendly."
"I would like to be able to build an Integration Bus cluster that is active-active."
"One drawback that I have found is that there are issues with using the Java connector."
"They should add connectors to banking applications and other specific industries."
"The next versions are moving toward container use. It would be a shame to make the product highly complex just to support one pattern of deployment. It is my hope that IBM continues to focus on practical functionality that is simple and cost-effective."
"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."
"Today, the IBM business rule engine, the DataPower is outside the Enterprise Service Bus. It's sold as a different feature or application. If it could be integrated, then it's able to handle a lot more of what we are doing now rather than just have a stateless ESB that you can't do much on, and a set of normal business rules."
"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."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
 

Pricing and Cost Advice

"IBM Integration Bus is expensive."
"IBM Integration Bus itself is prices fair but App-Connect is a bit expensive which we use in conjunction with it."
"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 price is reasonable considering the features we receive."
"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."
"The solution requires a license and is very expensive here in India."
"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 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."
