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

"There are always continuous improvements that are happening."
"The flexibility offered by Oracle Service Bus, especially in the latest versions, includes abstracting underlying processes and enabling drag-and-drop mappings from source to destination."
"What I found most valuable in Oracle Service Bus is its time to market. It's excellent."
"The main advantage of Oracle Service Bus is the possibility to integrate different systems using workflows and different architectures in the same product."
"It was very good at supporting high transactions, up to 300 transactions per second."
"With Oracle Service Bus, we can connect with different types of systems. Another feature I like the most is the security feature."
"The interface is fine and the solution is quite robust."
"Supports multiple protocol technologies and web services."
"The drag-and-drop features for connectors are very valuable."
"The learning curve for this solution is very good."
"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."
"I like the user-friendly system and development of the service-oriented architecture."
"The solution basically conforms to our standards."
"The solution's customer service is good."
"It's a consolidated product. It works and it does its job pretty well."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
 

Cons

"We have faced a problem with the heap memory side, but that is stable now."
"The error-handling capability can be improved"
"If they can containerize this, that would be nice. If they can provide docker images and offer support for those containers, that would be great."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
"It needs to support more adapters, because the integration points keep changing and new things keep coming up. It also needs to be more scalable."
"Security needs to be more integrated."
"The initial setup is likely complex for many organizations."
"The support for GraphQL needs to be improved, and the response time for global support could be faster."
"The customization can be a bit difficult."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"The server is very specific and it is very difficult to get experience with it."
"They should introduce better pricing for small companies."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"They should release upgrades more frequently."
"If I have to buy software, then it becomes expensive for me."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."

"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
