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

"The solution integrates external systems by providing a lot of APIs for external transactions, such as open purchase orders and sales orders."
"The routing and aggregation are the most valuable features. It's split and join."
"Oracle a good product."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"Performance is everything and this has proven itself over the years."
"The stability is consistently high, with only one notable issue encountered."
"Supports multiple protocol technologies and web services."
"It has improved the efficiency of development."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"WSO2 Enterprise Integrator may cost you about twenty-five thousand dollars annually per year compared to IBM Cloud Pak, which would cost you around one million dollars."
"The solution basically conforms to our standards."
"The stability is excellent."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"WSO2's analytics capability is good, considering the ELC support they provide."
"I like the user-friendly system and development of the service-oriented architecture."
 

Cons

"There are some loopholes in service and support."
"We have faced a problem with the heap memory side, but that is stable now."
"It would be ideal if they could optimize it a bit."
"Some unknown errors will sometimes happen and the error message isn't clear."
"It's very complex and hard to learn. There's a steep learning curve."
"Lacks sufficient cloud compatibility."
"The error-handling capability can be improved"
"The consolidation functionality is minimal, lacking advanced features for complex integrations."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"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."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"You cannot include the validation of XPath."
"We had some challenges with the installation of this solution."
"One of the reasons that we are looking for a replacement is their way of defining integration. The language of the XML structures that I use to describe the integrations are not that standard, and it's not easy to find people who are familiar with this approach."
