The Java Virtual Machine represents a key foundational technology at the heart of the Java industrial ecosystem. OpenJDK remains the central open source project from which most Java Virtual Machines and additional Java tools emanate, In September 2013, Azul Systems announced the Zulu effort jointly with Microsoft OpenTech, with Zulu joining Zing as JVM offerings from Azul. Zulu is an integrated component available when building Azure cloud VMs. In this presentation, Matt brings a mostly Microsoft audience up to speed on Java. He covers the history and milestones that outline the saga of Java since its invention. He also provides a novel viewpoint of the Java Virtual Machine as the core of the Java universe with six different point cuts across factors like Java code transformations, life cycle, platforms, editions, and vendors. Matt then explains Zulu, a new OpenJDK distribution built by Azul for use on Azure and other Windows platforms. He shows how Zulu in its first release supports garden variety application workloads same as other common JVMs, but with direct integration into the Azure platform configurator.

This Talk’s Purpose / Goals
 This talk is focused on Java for Azure
 This is not a “how to write a Java program” talk
 This is a talk about how Java fits into the Azure
landscape and why Zulu by Azul plays a big role.
 Purpose: Once you understand where Zulu fits,
you’ll know just enough to be dangerous...
 The “Azul makes the world’s greatest JVMs” stuff
will only come at the end, I promise...

High Level Agenda
 Java history, evolution, and current picture of
industry
 Zoom into the Java Virtual Machine, the
architectural heart of Java
 Zoom out, seeing where the JVM fits in the
greater application universe
 Focus back in on Azure and pick apart why Java
on Azure isn’t so weird as it initially sounds.
 Introduce and describe Zulu, a new OpenJDK
distribution offered by Azul Systems
5/3/20154
Notice: we’ll be laying a lot of ground work to get to the Azure parts

Azul’s Evolution in Java Context
Year Azul Java Milestone
1996 Sun ships Java 1.0. Codename “Oak”.
1999 Sun builds Java 1.2 w/ Swing and Browser plugin. First use of HotSpot
as trade name of JVM. “Java 2”, split as J2SE, J2EE, and J2ME
2002 Founded J2EE called best platform for web. J2SE 4.x solid for server apps, 1st
64-bit VM. BEA acquires Appeal, the JRockit VM creators.
2005 Vega J2 Version 5, Codename “Tiger”, is huge. BEA WebLogic 8.1 hot. “IBM
J9” VM replaces “IBM Classic” VM under WebSphere 6.1
2007 Oracle acquires BEA. JRockit VM kept intact over Oracle VM.
2010 Zing VE Oracle acquires Sun. Java and Sparc kept intact. JRockit pushed for
specialty workloads only.
2011 Zing LX Oracle ships JSE 7. OpenJDK becomes base codeline for JSE7.0. IBM
ships WAS 8.0 on J9 JDK6. Zing 5 released.
2013 Zing PE IBM ships WAS 8.5 and it can be configured to use J9 JDK7. OpenJDK
7 is released. IcedTea 6 is released. JRockit revived.
2013 Zulu OpenJDK 8 will be foundation of Oracle’s JSE 8.
2014 Zulu Ent OpenJDK 8 released in March. Zulu8 beats IcedTea and J9 to market.
