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 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 most valuable feature is its knowledge."
"DirX Directory is the best feature of the product: a very fast, stable LDAP directory."
"The role and attribute-based access control has been greatly improved."
"The flexibility of the product."
"The solution offers high performance."
"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."
"After using Azul Zing, it is almost a zero-incident situation because of the GCs."
"Zing has completely solved the garbage collection problem for us."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
"With Zing, we've now been able to re-allocate those tuning resources to general product development."
"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."
"With minimal effort, Zing has helped us improve our latency performance drastically."
 

Cons

"An overall modernization of the product is required in order to keep up with newer products."
"The price could be better. It would be better if they developed a better endpoint solution in the next release."
"The user interface could be more convenient for people that don't know the tool too intensively."
"Needs more available consultants and implementation partners."
"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."
"The Self-Service Portal is old school and it lacks easy accessibility for users."
"However, like every other great product, there is always something that can be improved."
"It is extremely expensive."
"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."
"The profiling tools included with Zing lag behind those available for Oracle's Java implementation."
"We have encounter stability issues and that has been a source of frustration at times."

Nothing major, but one nuance: Zing auto-adjusts internal config based on available CPUs, which can cause brief CPU spikes every few minutes. These are harmless, but can give ops/monitoring teams a...
