Executive SummaryUpdated on Mar 3, 2025

Oracle Service Bus and IBM WebSphere Message Broker compete in the integration and middleware domain. Oracle Service Bus seems to have the upper hand due to its simplicity and versatility in various integration scenarios, despite similar support challenges.

Features: Oracle Service Bus is light, simple to learn, and excels in integration via robust adapters and connectors. It offers strong routing, aggregation, and stability. IBM WebSphere Message Broker is valued for integration capabilities with large-scale transactions and legacy systems, providing reliable and secure data integration and processing.

Room for Improvement: Oracle Service Bus faces challenges with RESTful service compatibility, scalability, and a complex licensing model. It also needs more cloud-based adapter offerings. IBM WebSphere Message Broker should reduce its complexity, enhance decoupling from IBM MQ, and address high costs and GUI performance issues.

Ease of Deployment and Customer Service: OSB offers flexibility across environments with hybrid and public clouds, although users experience slow support response times and licensing difficulties. IBM WebSphere Message Broker primarily supports on-premises deployment with similar support issues and needs better response times and resolutions.

Pricing and ROI: OSB is considered expensive but offers enterprise agreements with cost savings, although its pricing model is challenging. IBM WebSphere Message Broker is also high-cost, often deterring potential customers. Both products have indeterminate ROI but are noted for their reliability in scaling and operations.

Offers large-sized business information processing with a time-saving setup and impressive stability

I primarily use two previews of the product for Dev and two for QA as part of the production process. Whatever tools our company is using, the cost of a license in IBM WebSphere Message Broker is about 80% of all these software or tools. The message routing capabilities satisfy workflow efficiency. The product supports message formats of XML, JSON, and SSID, which are around 24 KB to 50 KB in size. The solution supports communication protocols like STTP and TCP. Features like DataGraph need to be introduced in IBM WebSphere Message Broker. Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore. For the aforementioned version, our company professionals can solve the queries on their own without seeking support from IBM. During the installation of a prior version of IBM WebSphere Message Broker, sometimes I have to configure the failovers through the cluster, where issues arise, and I often seek help from the support team. The solution is being used by some medicine companies in our organization that receive sales orders from the EDR or JDE. I would not recommend the product to others as its becoming obsolete and they can rather choose a middleware solution from Amazon or Azure. But I would overall rate the product a nine out of ten.

Quotes from Members

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

Pros

"Performance-wise, this solution is really good."

"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."

"The transactions and message queuing are the most valuable features of the solution."

"The solution has good integration."

"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."

"Straightforward development and deployment."

"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."

"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."

More IBM WebSphere Message Broker pros

"API management and defining varying protocols are the most valuable features"

"The communication between applications is already defined, which means that you don't have to redefine your service infrastructure at the lower level."

"Overall it is a pretty good solution."

"It was very good at supporting high transactions, up to 300 transactions per second."

"It has improved the efficiency of development."

"Monitoring feature that allows tracking of the web's UI development."

"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."

"Service Bus is good at routing the transformation."

More Oracle Service Bus pros

Cons

"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."

"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."

"It is currently a weighty product."

"The product's features are not being upgraded or enhanced by the vendor"

"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."

"Technical support is good but they could have a better response time."

More IBM WebSphere Message Broker cons

"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."

"The main problem could be related to timeout issues. This can happen due to legacy systems that might not allow the use of microservices."

"It's very complex and hard to learn. There's a steep learning curve."

"The initial setup is likely complex for many organizations."

"There are issues, especially if you want to create some compensation in your service bin."

"The weak point of OSB is the single point of failure."

"We have faced a problem with the heap memory side, but that is stable now."

"The consolidation functionality is minimal, lacking advanced features for complex integrations."

Pricing and Cost Advice

"The licensing cost of IBM WebSphere Message Broker needs to be reduced"

"This product is more expensive than competing products."

"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."

"The price is very high and it's the main reason that we are searching for alternatives."

"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."

"The solution is expensive."

"IBM products are generally more stable and have more features, but also come at a greater cost."

"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."
