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

"Performance of the JVM, especially the C4 Pauseless Garbage Collection, for continuous application execution is the most valuable feature."
"With Zing, we've now been able to re-allocate those tuning resources to general product development."
"With minimal effort, Zing has helped us improve our latency performance drastically."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
"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."
"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."
"No other JVM on the market even comes close to competing with the Azul Zing."
"Faster web app implementation, when PHP dev is required by customers."
"Zend PHP Engine is more secure than any other framework, and I usually prefer Zend PHP Engine for big applications."
"The most valuable feature of this solution is the speed at which it compiles and sends the dynamic cache."
"Essentially, we get the best performance at very affordable costing."
"The fact that it is available open-source is the best feature."
"Zend Engine gives the flexibility to use external modules to easily expand the functionalities you need for your web project."
"Offers a complete environment to develop PHP applications. It is valuable because it allows you to have a complete stack (PHP, MySQL, Zend Server) enabling the building of a development environment, and to deploy to the production system."
"No issues with stability encountered."
 

Cons

"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."
"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."
"However, like every other great product, there is always something that can be improved."
"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."
"A general scripting language should be further developed and should be embedded into it."
"The main area that Zend needs to improve is to support asynchronous programming tasks, which is facilitated in PHP 7, but not at the same degree as HHVM.​​"
"In terms of improvement, it doesn't support concurrent processing. When we want to process anything on a concurrent basis, we have to divide it into a number of things, like a queue, or we have to run it using Cron jobs. We would like to have the capability to run any thread or process in parallel."
"Its object oriented programming language needs improvement."
"SQL queries have always been an issue with PHP, especially if you use large tables, which require caution from the side of the developer.​"
"Integrating AI tools would make PHP more competitive, as other tools already have AI features."
"Zend PHP Engine needs to improve the loading time of its libraries and make it faster."
"The biggest problem with PHP is you have to write lot of conditions or have to use a framework."
 

Pricing and Cost Advice

Information not available
"Its pricing depends on the number of users."

"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."
"Zend PHP Engine is not an expensive solution."
