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

"Oracle a good product."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"Supports multiple protocol technologies and web services."
"Even though we had been using Oracle BPEL, we had to go with Oracle Service Bus because it is able to handle JSON inputs, and we were amazed by its flexibility in accepting incoming messages."
"The features on offer are very complete; it's a very good product overall."
"From a technical perspective, the interface is fine and the solution is quite robust."
"We are using Oracle Service Bus to connect between API management and microservices, for example, for data transformation, bringing data from a specific form in one service to another form in a different service."
"API management and defining varying protocols are the most valuable features"
"The solution's technical support is very knowledgeable."
"The learning curve for this solution is very good."
"The built-in connectors help with quick connectivity to the platforms, and we are using this for both our banking and insurance clients."
"The connectors have been the most impactful features for handling integrations. I can use these connectors when I need specific connectivity with a third party, like a core banking system in BFSI. I don't need to do all the development. I take the specific connector, put in the IP address and password, and it takes care of everything."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The solution's customer service is good."
"The customer service executives are very responsive."
"The stability is excellent."
 

Cons

"The error-handling capability can be improved"
"The setup and onboarding process is hard, and it's made more difficult by a murky licensing process that needs to be clarified."
"Some unknown errors will sometimes happen and the error message isn't clear."
"There are several improvements that could be made to the product. Security needs to be more integrated, there are so many new security techniques on the market that could be integrated."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"The cost of the solution is too high. There are cheaper better solutions out there."
"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."
"The consolidation functionality is minimal, lacking advanced features for complex integrations."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"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."
"We had some challenges with the installation of this solution."
"I would like to see better documentation for the open-source version."
"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."
"The setup can be difficult for those not familiar with the solution."
"You cannot include the validation of XPath."
 

Pricing and Cost Advice
