Azul Zulu Prime System Tools 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.

This section lists system requirements for operating systems supported by Azul Zulu Prime System Tools (ZST).

The Azul Platform Prime with ZST can be installed on machines running the following operating systems using .rpm or .deb installers, as appropriate:

Operating System Versions

Red Hat Enterprise Linux

7 or later

CentOS

7 - 8.3

Oracle Linux

7

SLES

12 (SP3, SP4, SP5)

Ubuntu

16.04 - 20.04

Debian

9 (Stretch) and 10 (Buster)

Amazon Linux

1, 2

CoreOS

4.13.16

See the complete list of the supported kernels on the Software Downloads and Documents page. You need to obtain a username and password from [email protected] to access the page.

Notes

  • Ensure that OpenSSL 0.9.8 or later is installed.

  • Ensure that binutils are installed.

  • Ensure that Python version >= 2.6 and < 3.0 is installed.

  • When you use virtualized platforms, ensure that you follow Azul’s guidance for HW compatibility.

  • If your system has been updated to the latest kernels to resolve the Meltdown and Spectre CPU security flaws, install ZST version 5.20.5 or higher for all targets other than SLES 11 SP4, and use ZST 5.20.6 up to ZST 5.22.5 for SLES 11. SP4. SLES 11 SP4 is not supported starting with ZST 5.22.6.

ZST CPU Requirements

Azul Platform Prime with ZST can be installed on machines running the following CPU types.

  • 64-bit x86 CPUs

    • Intel® Xeon® server class processors released 2009 and later.

    • AMD Opteron™ server class processors released 2010 and later.

  • Azul Platform Prime is supported on systems with 2 or more vCores. Systems with higher core counts are obviously going to scale better, and provide lower scheduling related hiccup/jitter behavior.

ZST Memory Requirements

Azul Platform Prime with ZST requires the following amount of RAM:

  • 8+ GB RAM recommended

  • 512 MB hard minimum

Azul Platform Prime fundamentally leverages any provided memory across a wide operating range. Azul Platform Prime can fit within in the same resource profile as HotSpot, though unlocks a much higher upper memory limit without adversely affecting pause times.

Azul Platform Prime supports heap sizes from 512 MB to 20 TB.

With virtualized environments, we recommend using at least 7.5 GB of physical memory (for example, EC2 xlarge instances) per instance as minimum.

Cloud Computing Service Supported Instance Virtual Processor(s) RAM

Amazon Web Services

t2.medium 2

vCPUs

4 GB or larger

Microsoft Azure

Standard_B2s

2 vCPUs 4 GB or larger

Google Cloud Platforms

One of the benefits of Azul Platform Prime’s heap management behavior is that larger Java heaps result in better GC efficiency (often much better than HotSpot), without the typical higher-pause-time downsides often found with other JVMs. As a result, we often recommend systematically starting high, then walking down to determine the proper heap size that provides sufficient headroom to allow improved CPU efficiency for Java applications. Azul Platform Prime supports heap sizes from 512 MB to 20 TB when used with ZST. When used without ZST, the supported heap size ranges from 512 MB to 2.5 TB.

Hard Disk Storage Space Requirements

Azul Platform Prime with ZST requires the following amount of disk space:

  • 10 GB free disk drive space recommended for your ZVM instances to run Java applications

  • 8 GB minimum configuration is a spinning platter hard drive or enterprise quality SSD. Installation to a USB flash device is not recommended for production use.

  • 600 MB additional for JDK functions

ZST Platform Requirements

Azul Platform Prime with the ZST 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)
