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

"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."
"It was very good at supporting high transactions, up to 300 transactions per second."
"The solution integrates external systems by providing a lot of APIs for external transactions, such as open purchase orders and sales orders."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"The features on offer are very complete; it's a very good product overall."
"It's definitely stable."
"The flexibility offered by Oracle Service Bus, especially in the latest versions, includes abstracting underlying processes and enabling drag-and-drop mappings from source to destination."
"What I like most about Oracle Service Bus is that you can use it for many integrations. For example, you can use it for on-premises to on-premises integrations, on-premises to cloud integrations, and cloud to on-premises integrations."
"The productivity is the most valuable feature. It is very easy to write remediations."
"It has improved our time management because development is quicker."
"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."
"It was mostly easy to set up the product."
"The drag-and-drop features for connectors are very valuable."
"The solution basically conforms to our standards."
"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."
"WSO2's analytics capability is good, considering the ELC support they provide."
 

Cons

"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."
"The error-handling capability can be improved"
"This is a very, very expensive solution. It will cost a company a lot."
"The logging and error-handling framework can be improved."
"The pricing of the product could be better. It's a bit high."
"It's very complex and hard to learn. There's a steep learning curve."
"Some unknown errors will sometimes happen and the error message isn't clear."
"What needs improvement in Oracle Service Bus is the connectivity between adapters such as the Salesforce adapter and database adapters. The limited number of adapters compatible with Oracle Service Bus makes you want to switch to a different solution."
"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 setup can be difficult for those not familiar with the solution."
"I would like to see better documentation for the open-source version."
"The integration capabilities need to be improved."
"The server is very specific and it is very difficult to get experience with it."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"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 customization can be a bit difficult."
 

Pricing and Cost Advice

"The pricing is on the higher side."
"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."
"Oracle Service Bus is a bit expensive"
"The price of this solution is better than the subscription-based Mule ESB."
"I'm not aware of how much Oracle Service Bus costs."
"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 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."
"The open-source, unsupported version is available free of charge."
"It is a low-cost solution."
