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.

Quotes from Members

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

Pros

"I like the ease of deployment and the ease of implementation."
"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 is quite stable overall. We haven't witnessed any performance issues so far."
"The ability to master the process in one location."
"What I found most valuable in Oracle Service Bus is its time to market. It's excellent."
"We've been pleased with the level of technical support."
"It is stable."
"The routing and aggregation are the most valuable features. It's split and join."
"The installation process is easy."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The drag-and-drop features for connectors are very valuable."
"WSO2's analytics capability is good, considering the ELC support they provide."
"The learning curve for this solution is very good."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"The solution's customer service is good."
"It was mostly easy to set up the product."
 

Cons

"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"It's very complex and hard to learn. There's a steep learning curve."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."
"There are issues, especially if you want to create some compensation in your service bin."
"It would be ideal if they could optimize it a bit."
"The weak point of OSB is the single point of failure."
"Security features can be improved to better protect the server."
"The server is very specific and it is very difficult to get experience with it."
"I would like to see better documentation for the open-source version."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"If I have to buy software, then it becomes expensive for me."
"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."
"You cannot include the validation of XPath."
"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."
"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."
