Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of our clients is a signature company and developed on a classic Java enterprise application using OpenESB, and in one year they saved £20,000,000 on development and maintenance."
"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."
"The core is very stable."
"The process-oriented solution allows you to define choreography and orchestration."
"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
"Millions of people were connecting every month on the system and there were no issues."
"The stability is consistently high, with only one notable issue encountered."
"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."
"Supports multiple protocol technologies and web services."
"I like the ease of deployment and the ease of implementation."
"The most valuable feature is the adapters."
"From a technical perspective, the interface is fine and the solution is quite robust."
"Overall it is a pretty good solution."
"The routing and aggregation are the most valuable features. It's split and join."
 

Cons

"The documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"The documentation needs to be better."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"The error-handling capability can be improved"
"Security needs to be more integrated."
"This solution should work better with RESTful services."
"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."
"The setup and onboarding process is hard, and it's made more difficult by a murky licensing process that needs to be clarified."
"The technical support for this solution is not very good."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
 

Pricing and Cost Advice

"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."
"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."
"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."
"I'm not aware of how much Oracle Service Bus costs."
"Oracle Service Bus is a bit expensive"
"The pricing is on the higher side."
"We have an unlimited yearly license."
