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

"Supports multiple protocol technologies and web services."
"Monitoring feature that allows tracking of the web's UI development."
"It was very good at supporting high transactions, up to 300 transactions per second."
"The most valuable feature of this solution is that you can connect with different applications."
"With Oracle Service Bus, we can connect with different types of systems. Another feature I like the most is the security feature."
"There are always continuous improvements that are happening."
"The ability to master the process in one location."
"It has improved the efficiency of development."
"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."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
"The solution basically conforms to our standards."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"It's a consolidated product. It works and it does its job pretty well."
"The customer service executives are very responsive."
"It was mostly easy to set up the product."
 

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 consolidation functionality is minimal, lacking advanced features for complex integrations."
"Lacks sufficient cloud compatibility."
"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."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"Security needs to be more integrated."
"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"There are some loopholes in service and support."
"You cannot include the validation of XPath."
"The integration capabilities need to be improved."
"If I have to buy software, then it becomes expensive for me."
"The product's price is an area of concern where improvements are required."
"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 micro integrator should be improved. There is room for enhancement considering alternative integration components."
"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."
"The setup can be difficult for those not familiar with the solution."
 

Pricing and Cost Advice

"I'm not aware of how much Oracle Service Bus costs."
"The price of this solution is better than the subscription-based Mule ESB."
"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 pricing is on the higher side."
"We have an unlimited yearly license."
"Oracle Service Bus is a bit expensive"
"The cost is better than IBM Cloud Pak."
"It is a low-cost solution."
"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."
