Quotes from Members

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

Pros

"The core is very stable."
"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."
"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."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
"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."
"Millions of people were connecting every month on the system and there were no issues."
"The process-oriented solution allows you to define choreography and orchestration."
"The routing and aggregation are the most valuable features."
"From a technical perspective, the interface is fine and the solution is quite robust."
"With Oracle Service Bus, we can connect with different types of systems. Another feature I like the most is the security feature."
"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."
"What I found most valuable in Oracle Service Bus is its time to market. It's excellent."
"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 interface is fine and the solution is quite robust."
"We've been pleased with the level of technical support."
 

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."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"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."
"Cloud deployment is weak and needs to be improved."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"If you talk about the robustness of the product, TIBCO is better. The performance of TIBCO is better compared to Oracle."
"Some unknown errors will sometimes happen and the error message isn't clear."
"It's very complex and hard to learn. There's a steep learning curve."
"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."
"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."
"The pricing of the product could be better. It's a bit high."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
 

Pricing and Cost Advice

"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 Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
"The pricing is on the higher side."
"We have an unlimited yearly license."
"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."
