Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.

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

"Straightforward development and deployment."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"Integration and mapping are easy, which is a major advantage."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"The documentation, performance, stability and scalability of the tool are valuable."
"Setup is very easy; we had proper documentation for setup, so it didn't take much time, and setup takes a maximum of two or three hours and I can set up the complete application."
"The transactions and message queuing are the most valuable features of the solution."
"I like the user-friendly system and development of the service-oriented architecture."
"The solution basically conforms to our standards."
"The stability is excellent."
"The learning curve for this solution is very good."
"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."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The solution's technical support is very knowledgeable."
"The drag-and-drop features for connectors are very valuable."
 

Cons

"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"It is currently a weighty product."
"The images and size of the containers are too big and I think that they should be more lightweight."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"The solution can add container engines such as docker."
"My biggest complaint about this product is the price."
"The product's features are not being upgraded or enhanced by the vendor"
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"I would like to see better documentation for the open-source version."
"They should introduce better pricing for small companies."
"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."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"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."
"You cannot include the validation of XPath."
"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 setup can be difficult for those not familiar with the solution."
