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.

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

"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."
"We've had no issues with stability."
"The solution has good integration."
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
"Performance-wise, this solution is really good."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"It is a scalable solution...The setup is easy."

"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."
"My biggest complaint about this product is the price."
"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."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"The product's features are not being upgraded or enhanced by the vendor"
"Technical support is good but they could have a better response time."

"The solution is expensive."
