Changes Included in Release 24.08 of Azul Zing Builds of OpenJDK

Fri, 18 Oct 2024 13:53:56 +0000

Azul Zing Builds of OpenJDK, the optimized Java runtime within Azul Platform Prime , has reached the release of the 24.08 Stable Release line. Zing builds are available in two versions:

Stream Builds : Fast-moving monthly releases (end of the month) that include the latest features and changes in PSU releases. These are free for development and evaluation. Using Stream Builds in production requires an active subscription. Their version number is based on year and month. For instance, “24.07.0.0” is the July Stream Build of 2024.
Stable Builds : Builds that incorporate only CPUs, PSUs, and Azul Zing critical fixes and do not uptake new features and non-critical enhancements from Stream Builds. Stable Builds are our primary vehicle for delivering time-sensitive bug fixes to customers and are only available to Azul customers. Their version number is based on the Stream Build they originated from. For instance, “23.08.500.0” was derived from the August Stream Build of 2023 but already had multiple updates, as the 500 number indicates.

As stream builds happen in a fixed schedule, all changes are included in the release notes . Twice a year (in February and August), a Stream build becomes the new Stable build, providing a new version with many more improvements. In this post, we want to give you an overview of all the combined improvements in the 24.08 Stable Line.

Remotely Recording a JFR Log from a Container (Without Using the Command Line)

Tue, 07 May 2024 04:32:29 +0000

Java Flight Recorder (JFR) is the go-to technology for recording and viewing JVM and system metrics.

JFR records JFR logs which reveal much about the running application, the health of the JVM and the stability of the system. JFR logs are easily obtained by simply going into the command line / terminal and entering a few commands.

But what if you don’t have access to the command line or terminal directly on the system where the JVM is running, like when the JVM is running in a container?

Changes Included in Release 24.02 of Azul Zing Builds of OpenJDK

Azul Platform Prime is a Java platform with a modern, TCK-compliant JVM, Azul Zing, based on OpenJDK.

Zing provides low, consistent response latency of your Java workloads, higher total throughput and carrying capacity, faster warm-up, and infrastructure savings, achieved thanks to the C4 pauseless garbage collector , Falcon JIT compiler and other technologies created by Azul.

Zing Builds are available in two versions, either for evaluation or production use:

Controlling JIT Compiler Overhead to Avoid CPU Autoscaling

Wed, 01 Nov 2023 07:54:33 +0000

Today’s modern, containerized, elastically scaling Java clusters often rely on CPU utilization as the main trigger for scaling out new instances. Imperfect as this metric may be, it is ubiquitous to scale out new instances based on CPU utilization going over some limit. Often that limit is surprisingly low, somewhere around 40 to 50%.

Azul Platform Prime replaces OpenJDK’s HotSpot C2 compiler with the Falcon JIT compiler. Falcon generates much faster code than OpenJDK, allowing you to handle more transactions in a container before hitting your CPU utilization limit. And, Prime’s smoother and more consistent execution allows you to safely raise your CPU utilization to 60-70%, resulting in massive gains in carrying capacity for each container and lower overall cloud costs to handle your total Java workload.

Analyzing & Tuning Warm-up: Azul Zulu Prime Builds of OpenJDK

Sat, 01 Apr 2023 16:35:31 +0000

Warm-up is the time taken for the Java application to reach the optimum compiled code performance.

It is the task of the Just-in-Time (JIT) compiler to deliver optimal performance by producing optimized compiled code from application bytecode. This article will give you a basic understanding of how JIT compilation works and how to optimize warm-up using Azul Zulu Prime Builds of OpenJDK (Azul Zulu Prime JDK).
