Azul Zulu Prime Builds of OpenJDK System Requirements

Table of Contents

Looking for Zing? The Azul Zing Virtual Machine is now Azul Zulu Prime Builds of OpenJDK and part of Azul Platform Prime. Learn more.

Azul Platform Prime is a JDK that implements the umbrella Java Specification Request (JSR) for applicable Java Platform, Standard Edition (Java SE) versions (for example, JSR 336 for Java SE 7); and constitutes a “Compliant Implementation” under the specification licenses for the final release umbrella JSR specifications that Azul Zulu Prime JVM implements.

Azul Zulu Prime Builds of OpenJDK (Azul Zulu Prime JVM) include dynamic “just-in-time” (JIT) compiler technologies that adaptively compile Java bytecodes into optimized machine instructions, and manages the Java heap using Garbage Collector technology developed by Azul Systems.

Azul Zulu Prime JVM is supported on a variety of Linux distributions and x64 processor architectures. A current list of supported Linux operating systems and x64 architecture CPUs is covered in the remaining chapters and Release Notes.

Operating System Requirements

Azul Platform Prime can be installed on machines running the following operating systems.

Operating System Versions

Red Hat Enterprise Linux

7.3 or later


7.3 or later

CentOS/CentOS Stream

8 or later

Oracle Linux

7.3 or later


18.04 or later


12 SP3 or later


9 or later

Amazon Linux

1, 2



Photon OS

3.0 or later

Using Azul Zulu Prime JVM without Azul Zulu Prime System Tools (ZST) requires the memfd_create(2) system call. This system call is available since mainline Linux 3.17 and it was backported to the operating system versions listed above. If you want to run Azul Platform Prime on an older operating system, you need to install ZST in addition to Azul Zulu Prime JVM.

CPU Requirements

Azul Platform Prime runs on machines with the following 64-bit x86 CPUs:

  • Intel® Xeon® server class processors released since 2009

  • AMD EPYC™ and Opteron™ server class processors released since 2010

Memory Requirements

To install Azul Platform Prime, use the following memory requirements as a guideline:

  • Minimum Java heap size is 512 MB (-Xmx512M)

  • Depending on the available free RAM, up to 2.5 TB (2,500 GB) Java heap size in the default mode is possible and 20 TB with ZST

Hardware or Virtualized Platform Requirements

Azul Platform Prime runs on any of the following hardware or virtualized platforms:

  • x86-64 hardware

  • x86-64 virtual machines configured with Intel VT-x or AMD-V (e.g., Amazon EC2 (HVM), Azure, Oracle Virtual Box, Google Compute Engine, VMware)

  • x86-64 container-based systems (e.g., Docker, Kubernetes)

  • Arm64 hardware architecture
