Quotes from Members

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

Pros

"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 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."
"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."
"The process-oriented solution allows you to define choreography and orchestration."
"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."
"It was very good at supporting high transactions, up to 300 transactions per second."
"What's valuable is the ability to master the process in one location."
"The communication between applications is already defined, which means that you don't have to redefine your service infrastructure at the lower level."
"This product is not complicated and very easy to learn, and integrating this solution with other technologies is not difficult."
"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 solution integrates external systems by providing a lot of APIs for external transactions, such as open purchase orders and sales orders."
"It's definitely stable."
"Oracle Service Bus is a great tool for handling data and we use it to bridge the gap between the more modern technologies we have and our older technologies like mainframe."
 

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."
"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 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."
"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."
"It would be ideal if they could optimize it a bit."
"The weak point of OSB is the single point of failure."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
"This solution would benefit from having more cloud-based adapters."
"The microservices portion of Oracle Service Bus needs some improvement. Compared to MuleSoft, MuleSoft is much easier to use and deploy than what is currently available in Oracle Service Bus."
"If they can containerize this, that would be nice. If they can provide docker images and offer support for those containers, that would be great."
"The setup and onboarding process is hard, and it's made more difficult by a murky licensing process that needs to be clarified."
 

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."
"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
"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."
"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."
"We have an unlimited yearly license."
"The pricing is on the higher side."
"The price of this solution is better than the subscription-based Mule ESB."
"Oracle Service Bus is a bit expensive"
