Quotes from Members

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

Pros

"Millions of people were connecting every month on the system and there were no issues."
"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."
"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."
"The process-oriented solution allows you to define choreography and orchestration."
"API management and defining varying protocols are the most valuable features"
"I like the ease of deployment and the ease of implementation."
"For situations where they are many integration points, whether they are on-premises or in the cloud, this is a good solution."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"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."
"The features on offer are very complete; it's a very good product overall."
"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."
 

Cons

"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"The documentation needs to be better."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"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."
"The weak point of OSB is the single point of failure."
"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."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
"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."
"The pricing of the product could be better. It's a bit high."
"There are several improvements that could be made to the product. Security needs to be more integrated, there are so many new security techniques on the market that could be integrated."
"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."
"Security needs to be more integrated."
 

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