Featured Reviews

Mohakhan Khan - PeerSpot reviewer
Software Technical Expert at a tech vendor with 10,001+ employees
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.

Architecte SAP & Infrastructure at Teamwork
Good stability and good visibility but requires a better user interface
We're an SAP partner. We do also deploy some clients to the cloud, but 95% of the work we do with the solution is on-premises. I'd rate the solution six out of ten. I'm an architect, so I don't know enough about the implementation side to really be able to share any relevant first-hand experience in regards to setting the solution up.

Quotes from Members

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

Pros

"Zing has completely solved the garbage collection problem for us."
"No other JVM on the market even comes close to competing with the Azul Zing."
"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."
"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 drastically."
"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."
"After using Azul Zing, it is almost a zero-incident situation because of the GCs."
"There are many features of the solution that are quite useful. For us, the most valuable aspect may be visibility."
 

Cons

"We have encounter stability issues and that has been a source of frustration at times."
"It is extremely expensive."
"The profiling tools included with Zing lag behind those available for Oracle's Java implementation."
"However, like every other great product, there is always something that can be improved."
"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 solution could improve its user interface."

What is your experience regarding pricing and costs for Azul Zing?

What needs improvement with Azul Zing?
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...
