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

"Service Bus is good at routing the transformation."
"I like the ease of deployment and the ease of implementation."
"It's definitely stable."
"I am a part of the software developing team and I mainly use this solution for the integrating applications."
"Its ease of use is valuable. It's very easy to use. It's no code/low code. Oracle Middleware products are also rich in adapters."
"It has improved the efficiency of development."
"From a technical perspective, the interface is fine and the solution is quite robust."
"The communication between applications is already defined, which means that you don't have to redefine your service infrastructure at the lower level."
"The solution's customer service is good."
"The solution's technical support is very knowledgeable."
"The customer service executives are very responsive."
"The productivity is the most valuable feature. It is very easy to write remediations."
"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."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The built-in connectors help with quick connectivity to the platforms, and we are using this for both our banking and insurance clients."
"The most valuable aspect of the solution is the integration between core banking and other systems."
 

Cons

"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"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."
"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."
"If you talk about the robustness of the product, TIBCO is better. The performance of TIBCO is better compared to Oracle."
"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."
"The setup and onboarding process is hard, and it's made more difficult by a murky licensing process that needs to be clarified."
"There is significant room for improvement in the monitoring capabilities."
"The cost of the solution is too high. There are cheaper better solutions out there."
"The integration capabilities need to be improved."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"The configuration of the product is not an easy task for everyone."
"You cannot include the validation of XPath."
"They should introduce better pricing for small companies."
"For simpler tasks or simpler use cases, we avoid using WSO2 Enterprise Integrator because it is quite complex."
"The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems."
"The server is very specific and it is very difficult to get experience with it."
