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

"It was very good at supporting high transactions, up to 300 transactions per second."
"Overall, the solution is quite good and has lots of great features."
"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."
"It is stable."
"There are always continuous improvements that are happening."
"The stability is consistently high, with only one notable issue encountered."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"I like the ease of deployment and the ease of implementation."
"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."
"It's a consolidated product. It works and it does its job pretty well."
"The installation process is easy."
"It was mostly easy to set up the product."
"The built-in connectors help with quick connectivity to the platforms, and we are using this for both our banking and insurance clients."
"It has improved our time management because development is quicker."
"The learning curve for this solution is very good."
"The solution basically conforms to our standards."
 

Cons

"It's very complex and hard to learn. There's a steep learning curve."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"The weak point of OSB is the single point of failure."
"These issues are killing the business and productivity."
"The initial setup is likely complex for many organizations."
"The error-handling capability can be improved"

"The microservices portion of Oracle Service Bus needs some improvement. Compared to MuleSoft, MuleSoft is much easier to use and deploy than what is currently available in Oracle Service Bus."

"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
