Technical Architect at HCL Technologies

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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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.

Has API-led architecture and provides a unique, user-friendly, and scalable architecture for hosting APIs

There's room for improvement in multi-file transfer functionality. It's not convenient when using MuleSoft, and it should have better capability for handling large amounts of data. For example, applications like GoAnywhere can handle huge chunks of data, so the tool should also have something to facilitate that aspect of integration.

Quotes from Members

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

Pros

"Straightforward development and deployment."

"The documentation, performance, stability and scalability of the tool are valuable."

"IBM WebSphere Message Broker is one of the best middleware solutions"

"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."

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

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

"Integration and mapping are easy, which is a major advantage."

More IBM WebSphere Message Broker pros

"The most beneficial features of Mule ESB are the control plane and runtime plane."

"The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs."

"For complex cases, we employ the SSLi engine, whereas for simpler ones like healthcare or response data, such as EDI 270 or 271. We prefer to use an external XRT engine instead of handling it within the ESB for ease of management."

"I like that Mule ESB provides fast and good technical support."

"Mule Expression Language"

"We can use Java expressions anywhere in the flow."

"Mule ESB is a very easy-to-use and user-friendly solution."

"The cloud and integration abilities are most useful allowing us to use applications such as Salesforce and DataWeave."

More Mule ESB pros

Cons

"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."

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

"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."

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

"It is currently a weighty product."

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

"Technical support is very slow and needs to be improved."

"Stability and pricing are areas with shortcomings that need improvement."

More IBM WebSphere Message Broker cons

"The payment system needs improvement."

"MuleSoft is not so strong in method-based integration, so they're not so functional in that regard."

"From an improvement perspective, there should be fewer coding challenges for users in Mule ESB."

"The Anypoint platform consumes a lot of memory, and it would be great for developers if it were more lightweight."

"There are some issues with both stability and scalability."

"We would like the ability to use our own code. This would allow us to develop customizations with ease. Additionally, it would be nice to have more analytics or insights on the exchanged information between databases."

"Community editions need more attention."

"The initial setup is not easy."

More Mule ESB cons

Pricing and Cost Advice

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

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

"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."

"The solution is expensive."

"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."

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

"This product is expensive, but it does offer value for money."

"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."

"The price of the Mule ESB commercial version is expensive. However, they have a free community version."

"Regarding licensing and pricing, I find it somewhat flexible. They are more flexible with larger customers compared to small and medium ones, as their licensing model depends on ports and other factors. Large customers benefit from more flexibility in implementation and renewal compared to smaller ones."

"This product is cheaper than some offered by other vendors, although there is a problem because you have to pay for some third-party adapters."

"The various features and components for this solution are no longer free."

"The pricing must be improved."

"The licensing is yearly, and there are additional fees for services."

Overview

WebSphere Message Broker is an enterprise service bus (ESB) providing connectivity and universal data transformation for service-oriented architecture (SOA) and non-SOA environments. It allows businesses of any size to eliminate point-to-point connections and batch processing regardless of platform, protocol or data format.

IBM

For companies looking to modernize and unlock the value of existing on-premises systems and applications, an enterprise service bus (ESB) architecture serves as a critical foundation layer for SOA. When deployed as an ESB, the Mule runtime engine of Anypoint Platform combines the power of data and application integration across legacy systems and SaaS applications, with a seamless path to the other capabilities of Anypoint Platform and the full power of API-led connectivity.
