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 routing and aggregation are the most valuable features. It's split and join."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"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."
"This product is not complicated and very easy to learn, and integrating this solution with other technologies is not difficult."
"The solution integrates external systems by providing a lot of APIs for external transactions, such as open purchase orders and sales orders."
"It has improved the efficiency of development."
"The most valuable feature is the monitoring feature, where we can track the web's UI development."
"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."
"The solution's technical support is very knowledgeable."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"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."
"The built-in connectors help with quick connectivity to the platforms, and we are using this for both our banking and insurance clients."
 

Cons

"An area for improvement in Oracle Service Bus is the roadmap for its product launch. Currently, it's unclear, so Oracle should develop a roadmap for version 12c, so people can see what's coming out of that version of Oracle Service Bus. Cloud hosting is an additional feature I'd like to see in the next release of Oracle Service Bus."
"The consolidation functionality is minimal, lacking advanced features for complex integrations."
"The weak point of OSB is the single point of failure."
"There are some loopholes in service and support."
"Security needs to be more integrated."
"The main inconvenience is the composition between services; if you have six or seven services you call in the same process, it's very difficult and that's the main issue."
"The logging and error-handling framework can be improved."
"The main problem could be related to timeout issues. This can happen due to legacy systems that might not allow the use of microservices."
"The configuration of the product is not an easy task for everyone."
"They should introduce better pricing for small companies."
"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."
"The product's price is an area of concern where improvements are required."
"The integration capabilities need to be improved."
"You cannot include the validation of XPath."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"Most of the issues we run into with the WSO2 Enterprise Integrator deal with customizations."
