Flexible with high performance and good reliability
The solution scales well. As an example, there has been an American telecom service provider that had 20 million users, and the data of those user profiles had been stored on Dirx Directory, and they don't have any issues in retrieving the data and using it for any kind of services. Regarding our clients, the amount of users depends on if you have end users that don't really use this Directory or not. They are stored in this Directory and make use of the services that are administered via this Directory. There we are talking about millions. Then, you have administrators who configure the Directory and there we're talking about, let's say, hundreds of users.

Real-time charging has stayed consistent and cuts GC incidents while reducing cloud costs
The best features Azul Zing offers include no stop-the-world during the full GC. No stop-the-world pauses during full GC, and we hit higher TPS with fewer JVMs -- a real win for maintenance and cost. As an online charging system, we can't afford crashes or latency spikes. Before Zing, JVMs would hang and drop from the grid on missed heartbeats. GC tuning is also out-of-the-box -- no more time consuming manual tuning like with Oracle/OpenJDK with no significant outcome.

Quotes from Members

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

Pros

"The role and attribute-based access control has been greatly improved."
"The solution is extremely stable; typically if you don't change the setup, the configuration, or anything, it will be running for decades and nothing will happen as an issue."
"The solution offers high performance."
"The flexibility of the product."
"DirX Directory is the best feature of the product: a very fast, stable LDAP directory."
"The most valuable feature is its knowledge."
"No other JVM on the market even comes close to competing with the Azul Zing."
"With Zing, we've now been able to re-allocate those tuning resources to general product development."
"After using Azul Zing, it is almost a zero-incident situation because of the GCs."
"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."
"Performance of the JVM, especially the C4 Pauseless Garbage Collection, for continuous application execution is the most valuable feature."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
 

Cons

"The Self-Service Portal is old school and it lacks easy accessibility for users."
"An overall modernization of the product is required in order to keep up with newer products."
"Needs more available consultants and implementation partners."
"The user interface could be more convenient for people that don't know the tool too intensively."
"The price could be better. It would be better if they developed a better endpoint solution in the next release."
"The product provides an excellent framework but could use some polish on the front end to reduce the amount of configuration required for basic tasks."
"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."
"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."
"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."
"It is extremely expensive."
