Offers valuable features of API management and protocol definition
The initial setup process of Oracle Service Bus is quite easy. The installation of the product can be completed in one or two hours, but the total deployment time varies from case to case. I believe the entire deployment of Oracle Service Bus can be finished within a day. One engineer is enough to deploy the solution. The solution can be easily maintained.

Decreases the development timeframe and costs
The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems. Often, customers decide to develop using open-source tools like Spring Boot if there aren't many connectors required to avoid increasing costs. They'll develop this way and then deploy using APIM, the bare minimum needed. It is mainly required for very complicated setups with many connectors. In the implementations I've seen, people often used open-source tools because there weren't many third-party systems involved—just their organization's own systems. From WSO2 Enterprise Integrator, I expect them to bring up more and more connectors in the future. That's the main expectation. Having more connectors in various areas will help us when discussing new requirements. I don't have any specific use case right now, so I can't name a particular connector. But, as new technologies emerge, the relevant connectors should be there for those. WSO2 Enterprise Integrator mainly helps with the integration part, which can be simplified only if you have relevant connectors for whatever you're doing.

Quotes from Members

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

Pros

"The communication between applications is already defined, which means that you don't have to redefine your service infrastructure at the lower level."
"Monitoring feature that allows tracking of the web's UI development."
"It is stable."
"The interface is fine and the solution is quite robust."
"Service Bus is good at routing the transformation."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"It was very good at supporting high transactions, up to 300 transactions per second."
"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 connectors have been the most impactful features for handling integrations. I can use these connectors when I need specific connectivity with a third party, like a core banking system in BFSI. I don't need to do all the development. I take the specific connector, put in the IP address and password, and it takes care of everything."
"The solution's customer service is good."
"The productivity is the most valuable feature. It is very easy to write remediations."
"The drag-and-drop features for connectors are very valuable."
"The solution basically conforms to our standards."
"The installation process is easy."
"It's a consolidated product. It works and it does its job pretty well."
"WSO2's analytics capability is good, considering the ELC support they provide."
 

Cons

"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"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. Cloud hosting is an additional feature I'd like to see in the next release of Oracle Service Bus."
"Lacks sufficient cloud compatibility."
"Security features can be improved to better protect the server."
"The initial setup is likely complex for many organizations."
"There is significant room for improvement in the monitoring capabilities."
"The main problem could be related to timeout issues. This can happen due to legacy systems that might not allow the use of microservices."
"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."
"The product's price is an area of concern where improvements are required."
"They should release upgrades more frequently."
"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."
"They should introduce better pricing for small companies."
"The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"The integration capabilities need to be improved."
"One of the reasons that we are looking for a replacement is their way of defining integration. The language of the XML structures that I use to describe the integrations are not that standard, and it's not easy to find people who are familiar with this approach."
 

Pricing and Cost Advice

"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."
"Oracle Service Bus is a bit expensive"
"The price of this solution is better than the subscription-based Mule ESB."
"The pricing is on the higher side."
"I'm not aware of how much Oracle Service Bus costs."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"The cost is better than IBM Cloud Pak."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"It is a low-cost solution."
"The open-source, unsupported version is available free of charge."
"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
