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

"Setup is very easy; we had proper documentation for setup, so it didn't take much time, and setup takes a maximum of two or three hours and I can set up the complete application."
"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."
"The documentation, performance, stability and scalability of the tool are valuable."
"Message Broker is valuable because most of the applications are using MQ. Even in my current engagement, the few applications which I audit to onboard the bank are using MQ."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
"The most valuable feature is the monitoring feature, where we can track the web's UI development."
"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."
"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."
"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."
"I like the ease of deployment and the ease of implementation."
"The main advantage of Oracle Service Bus is the possibility to integrate different systems using workflows and different architectures in the same product."
"What I found most valuable in Oracle Service Bus is its time to market. It's excellent."
"Overall, the solution is quite good and has lots of great features."
 

Cons

"My biggest complaint about this product is the price."
"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 product's features are not being upgraded or enhanced by the vendor"
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"Technical support is good but they could have a better response time."
"Stability and pricing are areas with shortcomings that need improvement."
"The pricing of the product could be better. It's a bit high."
"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."
"Lacks sufficient cloud compatibility."
"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."
"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."
"While I have not used the latest versions, resource efficiency could be optimized, considering past experiences"
"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."
 

Pricing and Cost Advice

"IBM products are generally more stable and have more features, but also come at a greater cost."
"The price is very high and it's the main reason that we are searching for alternatives."
"The solution is expensive."
"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."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The solution is expensive."
"The price of this solution is better than the subscription-based Mule ESB."
"Oracle Service Bus is a bit expensive"
"I'm not aware of how much Oracle Service Bus costs."
"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."
