MANUEL VALDIVIA - PeerSpot reviewer
Senior Manager at a financial services firm with 1,001-5,000 employees
Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.

Quotes from Members

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

Pros

"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"It is a scalable solution...The setup is easy."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"The most valuable feature of IBM WebSphere Message Broker is the ability to facilitate communication with legacy systems, offering a multitude of great capabilities. For example, if there is a mainframe system in place with a web service serving as the front end. In that case, the solution enables efficient protocol transformations to convert all request payloads into a format that the legacy systems can accept, rendering the integration and transformation processes seamless and highly effective."
"What I found most valuable in Oracle Service Bus is its time to market. It's excellent."
"Overall it is a pretty good solution."
"There are always continuous improvements that are happening."
"What I like most about Oracle Service Bus is that you can use it for many integrations. For example, you can use it for on-premises to on-premises integrations, on-premises to cloud integrations, and cloud to on-premises integrations."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"The routing and aggregation are the most valuable features. It's split and join."
"The most valuable feature is the adapters."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
 

Cons

"They are expensive and not worth the money we are spending on them."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"I know that Message Broker was a very tightly copied product with another IBM product, that is, IBM MQ. I would like to have a little bit more decoupling from the IBM MQ because it should not be a prerequisite for IBM WebSphere Message Broker usage."
"The images and size of the containers are too big and I think that they should be more lightweight."
"Technical support is very slow and needs to be improved."
"The solution can add container engines such as docker."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"This solution should work better with RESTful services."
"These issues are killing the business and productivity."
"The logging and error-handling framework can be improved."
"The weak point of OSB is the single point of failure."
"The consolidation functionality is minimal, lacking advanced features for complex integrations."
"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"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."
"There is significant room for improvement in the monitoring capabilities."
 

Pricing and Cost Advice

"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"The solution is expensive."
"IBM products are generally more stable and have more features, but also come at a greater cost."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The solution is expensive."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"This product is more expensive than competing products."
"The price is very high and it's the main reason that we are searching for alternatives."
"I'm not aware of how much Oracle Service Bus costs."
"Oracle Service Bus is a bit expensive"
"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."
"The pricing is on the higher side."
"The price of this solution is better than the subscription-based Mule ESB."
