Senior Systems Engineer Information Technology and Services Mid-Market (51-1000 emp.) 2/21/2019 "Managing Zing by Systems Engineers" 4/5 What do you like best about Azul Platform Prime (Zing)? Zing comes in two parts; the Zing Virtual Machine, (ZVM, which is a Java Virtual Machine) and Zing Service Tools (ZST) which is software installed on Linux along with their kernel module that does memory management. As a Systems Engineer I find managing Zing in an enterprise environment very easy. Upgrading is simple. A ZST upgrade is not needed for every ZVM upgrade - multiple versions of the ZVM can run on the same ZST. ZSTs are packaged in RPMs, so all we do is "yum update" and "reboot". Planning/Sizing for Zing on hardware is a little different, but still straight forward. When the zing kernel module starts it immediately takes a chunk of RAM, an all ZVM memory allocation is done inside there. There is no risk of other operating system processes depriving Zing Java of heap space, as it's already taken by the kernel module. Licensing can either be done by a centralised server for all ZVMs to "dial home" to, or a static license file can be stored on the servers. Review collected by and hosted on G2.com. What do you dislike about Azul Platform Prime (Zing)? Early versions (years ago) of ZST didn't upgrade cleanly, we often had to double check that kernel modules were removed from the module tree correctly. However the more recent versions do not have this problem and our management of ZST is a lot smoother now. Review collected by and hosted on G2.com. Recommendations to others considering Azul Platform Prime (Zing): Highly recommended for people interested in high performance Java applications. Review collected by and hosted on G2.com. What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? We use Zing as the JVM underneath our low latency trading platform. It's memory management prevents a number of the normal Java GC related problems. It doesn't remove the issue entirely (Zing still has to pause to get a consistent state) but this is few and far between. Review collected by and hosted on G2.com.

" 5/5 What do you like best about Azul Platform Prime (Zing)? I install zing, use from application , i do not have to worry about my jvm, GC again , ever. Review collected by and hosted on G2.com. What do you dislike about Azul Platform Prime (Zing)? Really, nothing . Everything is super! I do not have anything bad to say about zing. Saved my life! Review collected by and hosted on G2.com. Recommendations to others considering Azul Platform Prime (Zing): Go for it for any low latency application , saves lot of time tuning jvm . Review collected by and hosted on G2.com. What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? GC stops prevents low latency applications behave properly. Our Solr servers runs on zing and it servers more than 750 requests a second on a a cluster with 100s of TB of data with latency less than 150 ms on average. Without zing it would have been impossible for us to run solr the way it is running. Review collected by and hosted on G2.com.

The best thing that we have experienced with zing is the decreased latency and ability to fine tune java virtual machine and its garbage collection process so as to be able to reduce latency in the application and thereby improve application performance as well. Its in memory cache is something that also helps the process of reducing latency. Review collected by and hosted on G2.com. What do you dislike about Azul Platform Prime (Zing)? The one area where there could be improvement is when the java virtual machine is first started, there is inherent latency and delay to bring the system up and running and this is something zine should be able to improve upon to make this experience even better. Review collected by and hosted on G2.com. Recommendations to others considering Azul Platform Prime (Zing): test zulu for the Java VM involved and the application. Review collected by and hosted on G2.com. What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? The main business problem that was being solved was to reduce the latency in application performance that requires considerable effort in fine tuning java virtual machine - zulu helped a lot in this regard to minimize the fine tuning effort.

Small-Business (50 or fewer emp.) 9/27/2018 "Zing JVM (review by open-source license holder)" 4.5/5 What do you like best about Azul Platform Prime (Zing)? Azul made a very sensible design decision by tightly integrating the memory management of the Zing JVM with the operating system. This allows the JVM to better leverage OS-level memory management features which can be seen in the low latency performance of Zing's C4 garbage collector. I've found the setup tools which accompany Zing very useful in suggesting which OS properties to tune in order to get the best JVM performance. Zing's online documentation is very detailed and easy to navigate. Zing's GC performance is impressive and I found GC pauses were measurably lower in the applications I have run on this VM. Review collected by and hosted on G2.com. What do you dislike about Azul Platform Prime (Zing)? I've found nothing to dislike about Zing. The VM gives predictable and low latency. The only price you pay for this is that you must use a Linux kernel that is supported by the Zing memory management subsystem which may not be the latest non-stock kernel. If you are running Zing in production this is unlikely to be an issue. Review collected by and hosted on G2.com. What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? I'm reviewing Zing as an open-source license holder but I work in the financial services / market data industry where having predictable and low latency is essential as unpredictable or long GC pauses could break SLAs.

The Zing runtime allows us to run smooth, hiccup free Java applications without the need for ongoing tuning of the garbage collection algorithm. Review collected by and hosted on G2.com. What do you dislike about Azul Platform Prime (Zing)? There is some additional overhead required, and it can be difficult to resize applications or add entirely new ones without having to completely restart the memory manager. Review collected by and hosted on G2.com. Recommendations to others considering Azul Platform Prime (Zing): It's a specialized product, but if you need what it offers then you should consider it. Review collected by and hosted on G2.com. What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? Our goal was to run time-sensitive client-server applications in Java. With the Sun/Oracle Java runtime we needed to allow lengthy start-up times and expect frequent garbage collection pauses during times when the application was busy. While Zing didn't remove the need for garbage collection, it did spread it out over time so that our application did not become unresponsive when we needed it the most.

Zing is basically a drop-in replacement for the oracle JVM. No code changes required, and the configuration is simplified. Review collected by and hosted on G2.com. What do you dislike about Azul Platform Prime (Zing)? The licensing was a bit difficult to get working correctly in a containerized environment. Review collected by and hosted on G2.com. Recommendations to others considering Azul Platform Prime (Zing): I would evaluate Zing before purchases. In circumstances where full garbage collection (stop-the-world) events are a problem, Zing will most certainly alleviate this issue. I would also lean heavily on their support team, which was very responsive in our experience. Review collected by and hosted on G2.com. What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? We tested zing out as a way to improve performance of Apache Solr.

Zing is a great JVM. Minimise GC and maximise JVM heap. Technical support is great! One of the best in the market both in terms of quality and response time. We also had a dedicated Azul engineer to assist us with the setup and during major incidents involving Zing. Review collected by and hosted on G2.com.

What problems is Azul Platform Prime (Zing) solving and how is that benefiting you? Zing helped us reduce the latency for high percentiles by allowing us to operate Cassandra with a higher heap size (higher than the recommended value) and a low GC impact.
