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

"I am a part of the software developing team and I mainly use this solution for the integrating applications."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"The routing and aggregation are the most valuable features. It's split and join."
"Service Bus is good at routing the transformation."
"The solution integrates external systems by providing a lot of APIs for external transactions, such as open purchase orders and sales orders."
"This product is not complicated and very easy to learn."
"It has improved the efficiency of development."
"The stability is consistently high, with only one notable issue encountered."
"It was mostly easy to set up the product."
"I like the user-friendly system and development of the service-oriented architecture."
"The productivity is the most valuable feature. It is very easy to write remediations."
"The solution basically conforms to our standards."
"It's a consolidated product. It works and it does its job pretty well."
"The drag-and-drop features for connectors are very valuable."
"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
 

Cons

"This solution would benefit from having more cloud-based adapters."
"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."
"It would be ideal if they could optimize it a bit."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"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."
"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."
"The pricing of the product could be better. It's a bit high."
"We have faced a problem with the heap memory side, but that is stable now."
"If I have to buy software, then it becomes expensive for me."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"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."
"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."
"The product's price is an area of concern where improvements are required."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
 

Pricing and Cost Advice

"Oracle Service Bus is a bit expensive"
"The pricing is on the higher side."
"We have an unlimited yearly license."
"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."

"The price of this solution is better than the subscription-based Mule ESB."
"The open-source, unsupported version is available free of charge."
"It is a low-cost solution."
"The cost is better than IBM Cloud Pak."
"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 solution costs about 20,000 or 30,000 euros per year, per instance."
"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
