Quotes from Members

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

Pros

"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."
"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."
"The ability to master the process in one location."
"The most valuable feature is the adapters."
"The stability is consistently high, with only one notable issue encountered."
"API management and defining varying protocols are the most valuable features"
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"The main advantage of Oracle Service Bus is the possibility to integrate different systems using workflows and different architectures in the same product."
"Its ease of use is valuable. It's very easy to use. It's no code/low code. Oracle Middleware products are also rich in adapters."
"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."
 

Cons

"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."
"The documentation needs to be better."
"Cloud deployment is weak and needs to be improved."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"There is significant room for improvement in the monitoring capabilities."
"We have faced a problem with the heap memory side, but that is stable now."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
"There are issues, especially if you want to create some compensation in your service bin."
"Security features can be improved to better protect the server."
"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."
"The pricing of the product could be better. It's a bit high."
 

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."
"Oracle Service Bus is a bit expensive"
"The pricing is on the higher side."
"I'm not aware of how much Oracle Service Bus costs."
"We have an unlimited yearly license."
"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."
