It has helped us improve our latency performance drastically
As a large scale high performance trading platform serving the high frequency trading community, latency has always been critical for our clients. Before using Azul Zing JVM, we would have had to spend a lot of effort tuning our JVM GC and profiling our application to minimize latency, which is…

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

Pros

"No other JVM on the market even comes close to competing with the Azul Zing."
"With minimal effort, Zing has helped us improve our latency performance drastically."
"GC Pause times are maintained in low milliseconds, which is beneficial for applications with high volume, high memory allocation rate, and a high memory footprint, and it also increases throughput by approximately 20-25% as compared to Oracle Java Development Kit based on some tests that I have done with real applications."
"Zing has completely solved the garbage collection problem for us."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
"The non-stop garbage collector (C4 - Continuously Concurrent Compacting Collector) is the most valuable feature."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
"Performance of the JVM, especially the C4 Pauseless Garbage Collection, for continuous application execution is the most valuable feature."
"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."
"The VPN service is quite useful."
"The technical support from IBM is very good and responsive."
"WebSphere Application Server is very stable."
"IBM WebSphere Application Server is one of the best servers due to its stability and paid license."
"What's most valuable in IBM WebSphere Application Server is its resilience. When you use the solution, you know that after the communication has been done, there will be no doubt that the data has reached its destination."
"This solution is easy to use with a GUI that is intuitive and very helpful."
"It's an awesome solution. Compared to everything else that's out there in the market right now, IBM MQ is hands down the best solution available and that's based on 40 years of IT experience."
 

Cons

"However, like every other great product, there is always something that can be improved."
"The profiling tools included with Zing lag behind those available for Oracle's Java implementation."
"It is extremely expensive."
"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."
"The licensing over non-production environments considerably affects the cost of our solution as a software vendor."
"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."
"We have encounter stability issues and that has been a source of frustration at times."
"Since we've been monitoring it directly ourselves, we've found that there has been an increase in the number of failures. The failures result in deadlock processes that generate very little to no troubleshooting logs."
"The solution consumes hardware."
"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."
"When we run into memory or locking issues, we resort to using third-party tools. However, it would be preferable to have native tools for debugging this type of problem."
"IBM needs to pay attention to market changes more quickly. We now have Java 9 and very soon Java EE8. We do not want to wait for two or three years after their release until they are supported by the new version."
"It should be able to serve more concurrent requests like Oracle. Oracle has more powerful stability, availability, and real-time serving."
"The solution is very expensive compared to an open-source stack."
"The security could be better."
 

Pricing and Cost Advice

Information not available
"I don't remember the price, but there are no additional costs."
"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive. Bargain well and try to get as much discount as possible. Discounts of 85% are possible. Without the discount, I think the product is overrated."
"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"It costs more than some of the others, but, you get what you pay for."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"The solution is quite expensive."
"The price of this product is higher than that of competitors."
"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."
