Allows seamless integration and connectivity with different types of systems
I would suggest using this solution. Oracle Service Bus is very good. Any organization can use it. So it's very robust and scalable, and its security features are very good. Overall, I would rate the solution an eight out of ten because there are some loopholes in service and support. Sometimes, when we have issues and go to Oracle support, they will not give us solutions. Instead, they will ask for so many log files and emails. The product is good, but the support is not.
Ritesh_Shah - PeerSpot reviewer
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.
