Standardized our Java estate and have reduced licensing costs while maintaining strong support
Azul Zulu's ability to allow us to standardize our Java estate on a single and well-supported platform stands out as one of its best features. This standardization simplifies our compliance audits and ensures all our applications receive timely security updates.Azul Zulu positively impacts our organization by providing a platform that allows us to standardize Java on a well-supported platform. Without the high cost associated with other proprietary vendors, Azul Zulu provides an excellent platform for running our applications.

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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

"We achieved specific outcomes from using Azul Zulu by reducing our Java licensing and support costs by approximately 70% when compared to our previous Oracle contract."
"The transactions and message queuing are the most valuable features of the solution."
"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."
"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."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"Straightforward development and deployment."
"Performance-wise, this solution is really good."
 

Cons

"Improvements for Azul Zulu could include more automated tools for unused code visibility integrated directly into the standard portal to help further optimize our cloud footprints."
"The product's features are not being upgraded or enhanced by the vendor"
"The installation configuration is quite difficult."
"Technical support is good but they could have a better response time."
"Technical support is very slow and needs to be improved."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"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."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
 

Pricing and Cost Advice

Information not available
"The solution is expensive."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"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."
"The solution is expensive."
"IBM products are generally more stable and have more features, but also come at a greater cost."
