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

"For situations where they are many integration points, whether they are on-premises or in the cloud, this is a good solution."
"We are using Oracle Service Bus to connect between API management and microservices, for example, for data transformation, bringing data from a specific form in one service to another form in a different service."
"Oracle a good product."
"The most valuable feature of this solution is that you can connect with different applications."
"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."
"The routing and aggregation are the most valuable features. It's split and join."
"The most valuable feature is the monitoring feature, where we can track the web's UI development."
"It is stable."
"The stability is excellent."
"WSO2's analytics capability is good, considering the ELC support they provide."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"The solution's customer service is good."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The customer service executives are very responsive."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"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."
 

Cons

"The initial setup is likely complex for many organizations."
"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."
"With the most recent version, 12c, I'm still getting used to using it, learning how to use it, how to configure it. The Oracle documentation is OK, but there aren’t a lot of good examples for me to follow."
"This solution would benefit from having more cloud-based adapters."
"If you talk about the robustness of the product, TIBCO is better. The performance of TIBCO is better compared to Oracle."
"We have faced a problem with the heap memory side, but that is stable now."
"There are issues, especially if you want to create some compensation in your service bin."
"The pricing of the product could be better. It's a bit high."
"The customization can be a bit difficult."
"Most of the issues we run into with the WSO2 Enterprise Integrator deal with customizations."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"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."
"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 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."
"I would like to see better documentation for the open-source version."
 

Pricing and Cost Advice

"The pricing is on the higher side."
"Oracle Service Bus is a bit expensive"
"We have an unlimited yearly license."
"This is a very expensive product and the price varies depending on factors such as the number of processors and the number of users. Our licensing fees are approximately $300,000."
"The price of this solution is better than the subscription-based Mule ESB."
"I'm not aware of how much Oracle Service Bus costs."
"It is a low-cost solution."
"The cost is better than IBM Cloud Pak."
"The open-source, unsupported version is available free of charge."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
