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.

Effective data transformation and integration in complex environments with high functionality
Something that could be improved in WSO2 Enterprise Integrator is that the problem is not a lack of capability or functionalities. The problem is that it is a very complex environment. To put your hand on this environment is a very demanding task. This is the real problem. The problem is not about the product, but about the complexity to manage, to configure, to decide what to do. I have some experience using SAP R/3. It seems to me something similar. When you have to configure a situation with a client, especially for a client not in an industrial sector, but in a service sector, it is quite usual that you are in trouble for some reason. This is always the story that I found in the implementations I have done. Maybe there are only three or four big problems, in some other cases there are more than that, but this is the situation usually. For WSO2 Enterprise Integrator, not the same, but I must say it is quite often there is a need to put together some pieces and make it work in a coordinated way.

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 is flexible, easy to use, and easy to configure."
"It is one of the most stable products which I have seen in the market."
"We can have multiple endpoints, and we can integrate different applications from different platforms. In a large-scale enterprise setup, it becomes so easy to establish communication between applications. You can connect an application to other applications, other legacy applications, and databases. You can also connect with those applications that are in the cloud. You can connect with other well-known applications, such as Salesforce, SAP, and Workday, by using IBM Integration Bus."
"The most valuable feature is the security."
"It's stable across multiple platforms and across multiple applications."
"The most valuable feature is that it's robust and its time to market is very short."
"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."
"The stability is mostly pretty good."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"The solution's technical support is very knowledgeable."
"The solution basically conforms to our standards."
"The customer service executives are very responsive."
"The stability is excellent."
"The drag-and-drop features for connectors are very valuable."
"It was mostly easy to set up the product."
"The installation process is easy."
 

Cons

"The memory footprint should be minimized."
"IBM doesn't really have a very strong community surrounding the product."
"The product could be improved by including more resources on SQL."
"The solution’s pricing could be improved."
"Migrating to this solution is complex and it would be helpful if they had a way to convert existing integrations."
"To scale virtically, is difficult."
"This product uses the PVU (Processor Value Unit) license model from IBM, and it is something that should be improved."
"I would like for them to make the training much easier."
"If I have to buy software, then it becomes expensive for me."
"The integration capabilities need to be improved."
"The customization can be a bit difficult."
"The setup can be difficult for those not familiar with the solution."
"The server is very specific and it is very difficult to get experience with it."
"I would like to see better documentation for the open-source version."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"There are a lot of security settings that when you apply you have to re-apply again every time you modify a setting. It is something that really needs to be enhanced."
