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

"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"The solution has good integration."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"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."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"Performance-wise, this solution is really good."
"Straightforward development and deployment."
"We are using Oracle Service Bus to connect between API management and microservices, for example, for data transformation, bringing data from a specific form in one service to another form in a different service."
"In summary, this is a very complete product and it works well for us."
"I am a part of the software developing team and I mainly use this solution for the integrating applications."
"The solution is quite stable overall. We haven't witnessed any performance issues so far."
"Even though we had been using Oracle BPEL, we had to go with Oracle Service Bus because it is able to handle JSON inputs, and we were amazed by its flexibility in accepting incoming messages."
"The most valuable feature is the adapters."
"It is stable."
"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."
 

Cons

"The product's features are not being upgraded or enhanced by the vendor"
"They are expensive and not worth the money we are spending on them."
"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."
"Stability and pricing are areas with shortcomings that need improvement."
"The images and size of the containers are too big and I think that they should be more lightweight."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"I find the installation configuration is quite difficult compared to other solutions."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"It's very complex and hard to learn. There's a steep learning curve."
"The weak point of OSB is the single point of failure."
"It would be ideal if they could optimize it a bit."
"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."
"It needs to support more adapters, because the integration points keep changing and new things keep coming up. It also needs to be more scalable."
"The cost of the solution is too high. There are cheaper better solutions out there."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
 

Pricing and Cost Advice

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