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 stability is consistently high, with only one notable issue encountered."
"With Oracle Service Bus, we can connect with different types of systems. Another feature I like the most is the security feature."
"Performance is everything and this has proven itself over the years."
"Oracle Service Bus is a great tool for handling data and we use it to bridge the gap between the more modern technologies we have and our older technologies like mainframe."
"Service Bus is good at routing the transformation."
"It's definitely stable."
"I like the ease of deployment and the ease of implementation."
"What's valuable is the ability to master the process in one location."
"The solution's customer service is good."
"The stability is excellent."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The drag-and-drop features for connectors are very valuable."
"The productivity is the most valuable feature. It is very easy to write remediations."
"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 most valuable aspect of the solution is the integration between core banking and other systems."
"It's a consolidated product; it works and it does its job pretty well."
 

Cons

"We have faced a problem with the heap memory side, but that is stable now."
"The pricing of the product could be better. It's a bit high."
"If you talk about the robustness of the product, TIBCO is better. The performance of TIBCO is better compared to Oracle."
"Lacks sufficient cloud compatibility."
"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"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."
"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"There are a lot of security settings that when you apply you have to re-apply again every time you modify a setting."
"The server is very specific and it is very difficult to get experience with it."
"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."
"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."
"The setup can be difficult for those not familiar with the solution."
"The scalability is not strong. If you want to scale it you have to install multiple servers."
"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."
"They should release upgrades more frequently."
