Scalable and easy to maintain
One of the most valuable features is the scalability. Whenever it's required, we can add more servers and scale. We can actually use specific servers for specific stuff. Unlike in other solutions, now we can implement one server purely dedicated to core-banking-related API. This is very important when it comes to the PCI DSS certification.

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 platform's most valuable feature is data transformation."
"The ability to compliment out-of-the-box integration components with small custom code."
"Fiorano offers multiple adaptors for various interface languages, making it easy to cater to a variety of interfaces."
"One of the most valuable features is the scalability. Whenever it's required, we can add more servers and scale. We can actually use specific servers for specific stuff. Unlike in other solutions, now we can implement one server purely dedicated to core-banking-related API. This is very important when it comes to the PCI DSS certification."
"Fully functional interfaces and web services are up in hours, not days, so we spend more time designing XSD than setting up the service."
"It has vastly improved the speed of delivery for custom integrations."
"It's a consolidated product. It works and it does its job pretty well."
"The installation process is easy."
"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."
"The stability is excellent."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"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."
"It has improved our time management because development is quicker."
"The solution's customer service is good."
 

Cons

"Error logging is not very user-friendly. It requires the error logging to be configured in many different places."
"Fiorano ESB could be improved by becoming more user-friendly."
"Error descriptions are not user friendly."
"Fiorano ESB could be improved by becoming more user-friendly. Most of the pages and generated reports on API usage are already there, but they could be more user-friendly. There could be more selections added to generate reports. Overall, though, Fiorano suits all our needs and has good functionality."
"Fiorano ESB's logging feature and data availability need improvement."
"The setup can be difficult for those not familiar with the solution."
"The integration capabilities need to be improved."
"The product's price is an area of concern where improvements are required."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"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."
"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."
"The server is very specific and it is very difficult to get experience with it."
 

Pricing and Cost Advice

"I rate the product's pricing a five out of ten."
"The open-source, unsupported version is available free of charge."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"The cost is better than IBM Cloud Pak."
"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"It is a low-cost solution."
