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.

Has worked seamlessly in complex clustered environments and supports long-term development efforts
IBM WebSphere Application Server is currently at version 9.0.5.23. In recent months, they released fix 23, as they periodically release fixes. Previously, they frequently increased versions, but now they maintain 9.0.5 with different releases. It's based on Java J2EE 7 and Java SDK 1.8. Oracle announced that 2030 will be the last year when Java SDK 1.8 will be supported. Oracle currently deploys Java 2.x in parallel, with the latest being version 25. The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7. I haven't found any white papers or official documentation from IBM outlining their trajectory post-2030.

Quotes from Members

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

Pros

"We've had no issues with stability."
"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."
"One of the most valuable features might be the stability of the IBM WebSphere Application Server."
"I find IBM support to be very nice."
"The solution's data consistency is great and very reliable, which is critical for us in a transitional scenario and the most important feature that we count on."
"IBM WebSphere Application Server is the ultimate product; there is nothing superior to IBM WebSphere Application Server, and while there are other options such as Tomcat, JBoss, and Oracle's solution, IBM WebSphere Application Server stands above them all."
"It integrates well with the Tivoli Federated Identity Management system, which works as a single sign-on mechanism for other e-services that we have shared with other clients."
"We have about 3,000 users concurrently using this application, and it has achieved more than 99.9% up time which has resulted in increased productivity and efficiency."
"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."
"IBM WebSphere Application Server is easy to use."
 

Cons

"It needs a better update daemon. At this time the process is manual and could be an issue on multiple desktop deployments."
"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."
"While WebSphere mostly supports IBM HTTP Server (IHS) as the web server plugin, I think it would be beneficial if it also supported Apache and NGINX web servers. That would give customers more flexibility in their choices."
"The installation has room for improvement."
"The availability of the solution needs improvement. The product should be more enhanced and responsive."
"I find the server okay, however, using the Maker instance, the Moving instance, and the Change instance is a little bit complicated without WebSphere knowledge."
"In the next release of this solution, I would like to see support for the Arabic language."
"IBM WebSphere Application Server hasn't changed much. It's still a heavyweight for any company compared to what you get. Unless your code base is deeply linked with it, I don't think it's a great idea to go with this solution. The current trend is toward modularity and containerization, and given the product's requirements, containerization will be difficult. There is a memory requirement as well."
"I think that this is a good product but I think that the cloud environment could be improved. I think that the future is in the utilization of the product in a product as a service way which is something that is lacking at this moment."
"The solution consumes hardware."
 

Pricing and Cost Advice

"When you purchase Maximo, you get WebSphere for free."
"The solution is quite expensive."
"The licensing cost is 1,000 of euros for a 30-year table."
"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
