Azul produces Zing, a Java Virtual Machine (JVM) and runtime platform for Java applications that is designed to remove memory limitations and scale elastically. The company was formerly known for its Vega Java Compute Appliances (JCAs), specialized hardware designed to massively scale the usable compute resources available to Java applications. Zing utilizes and improves on the software technology developed for the Vega hardware.
Zing became generally available October 19, 2010. The product includes a JVM, management tool and monitoring tool Zing is based on established technology from Azul that allows existing Java applications to scale to dozens of CPU cores and hundreds of gigabytes of memory 'elastically', meaning resources can also scale up and down based on real-time demands, and without garbage collection pauses present in other Java runtimes.
The Zing JVM is 100% Java-compatible and based on Oracle HotSpot. Where a typical Java Virtual Machine uses static heap sizes and reaches a practical size limitation due to garbage collection pauses, the Zing JVM implements Azul's C4 (Continuously Concurrent Compacting Collector) garbage collection software technology, allowing heap sizes of hundreds of GBs without pauses. Zing also utilizes Azul's technology for elastic memory, which allows memory heaps for Java instances to grow and shrink based on load.
The Zing Resource Controller is a tool for systems administrators that provides a high level view of Java application infrastructure and automatically scales memory heap size up and down dynamically as applications require. This dynamic heap scaling removes the need for most JVM and GC tuning.
Zing Vision provides low overhead production visibility of running Java applications using statistical information that is already available from processing occurring within the JRE.
Zing is available for Linux and Solaris, and requires x86-based hardware with Intel Nehalem or AMD Opteron processors.
Azul also produces the jHiccup open source performance measurement tool for Java applications. It is designed to measure the stalls or "hiccups" caused by an application's underlying Java platform.
Azul's Java Compute Appliances (JCAs) were designed to massively scale up the usable compute resources available to Java applications. A proxy Java Virtual Machine (JVM) installed on the existing system will transparently redeploy Java applications to the Azul appliance, the latest version of which, the Vega 3, can contain up to 864 processor cores and 768 GB of memory.

Famous quotes containing the word products:
“All that is told of the sea has a fabulous sound to an inhabitant of the land, and all its products have a certain fabulous quality, as if they belonged to another planet, from seaweed to a sailor’s yarn, or a fish story. In this element the animal and vegetable kingdoms meet and are strangely mingled.”
—Henry David Thoreau (1817–1862)
“The reality is that zero defects in products plus zero pollution plus zero risk on the job is equivalent to maximum growth of government plus zero economic growth plus runaway inflation.”
—Dixie Lee Ray (b. 1924)
“Good wine needs no bush,
And perhaps products that people really want need no
hard-sell or soft-sell TV push.
Why not?
Look at pot.”
—Ogden Nash (1902–1971)
