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.

"It's definitely stable."
"The solution is stable, very scalable, and the installation is quite straightforward, and we've been pleased with the level of technical support."
"In summary, this is a very complete product and it works well for us."
"For situations where they are many integration points, whether they are on-premises or in the cloud, this is a good solution."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
"The stability is excellent."
"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."
"The solution basically conforms to our standards."
"The customer service executives are very responsive."
"It was mostly easy to set up the product."
"WSO2's analytics capability is good, considering the ELC support they provide."
 

Cons

"We have faced a problem with the heap memory side, but that is stable now."
"The initial setup is likely complex for many organizations."
"The cost of the solution is too high. There are cheaper better solutions out there."
"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."
"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"Some unknown errors will sometimes happen and the error message isn't clear."
"The setup and onboarding process is hard, and it's made more difficult by a murky licensing process that needs to be clarified."
