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

"Monitoring feature that allows tracking of the web's UI development."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"The interface is fine and the solution is quite robust."
"Supports multiple protocol technologies and web services."
"It has improved the efficiency of development."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or Web services through different protocols."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"It was very good at supporting high transactions, up to 300 transactions per second."
"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."
"The stability is excellent."
"The productivity is the most valuable feature. It is very easy to write remediations."
"While I am still exploring the solution, I've so far been pretty satisfied with it."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"The solution's customer service is good."
"WSO2's analytics capability is good, considering the ELC support they provide."
"It has improved our time management because development is quicker."
 

Cons

"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."
"The interface console is very slow. Even in production, we need to increase the RAM or CPU. And even after that, the performance is still not good in production."
"The error-handling capability can be improved"
"There are some loopholes in service and support."
"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."
"The technical support for this solution is not very good."
"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."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"They should release upgrades more frequently."
"The customization can be a bit difficult."
"I would like to see better documentation for the open-source version."
"One of the reasons that we are looking for a replacement is their way of defining integration. The language of the XML structures that I use to describe the integrations are not that standard, and it's not easy to find people who are familiar with this approach."
"The configuration of the product is not an easy task for everyone."
"You cannot include the validation of XPath."
"The setup can be difficult for those not familiar with the solution."
"The customization can be a bit difficult."
