This Talk’s Purpose / Goals
Welcome to all Houston JUG members
 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...

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.

distribution offered by Azul Systems

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
5
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.

On Premise
This is the general “use this software” case. Install and go.
 Use native packaging to install Zulu like any other download:
.msi
.rpm
or just use a Zip file.
 Virtualization also encouraged:

.deb
.dmg
IaaS Using Azure
Azure provides a choice of OS to setup a VM. After that, adding anything else is up to you.

SaaS on Azure
Beyond the JVM is the realm of Azul partners
d.
 Microsoft partners working on SaaS offerings using Zulu as
Java runtime
– Hadoop by Hortonworks
– IBMs Liberty WAS Profile
 Microsoft Open Tech actively promoting Zulu for their Java
efforts. Search opentech for “Java” for list.
– https://msopentech.com/?s=java
 Azul partner ecosystem rich and growing
– We welcome any SaaS deployments on Zulu and on Zing
– Many SaaS operators often choose Zing for powerhouse
infrastructure
– Crossover into other providers (ie. AWS and Rackspace)

Java on Azure
Now that you are on Azure, no matter which computing context, you’ve got help
 Java connectors to Azure web services
– Access Control, Blob Service , Media Services, Queue
Services, Service Bus Queues, SQL Database and Table
Service
 Build facilities to use Azure for dev use cases
– Jenkins, Hudson, Ant, Application Insights, JetBrains
TeamCity
 Additional Site construction choices
– Tomcat, Jetty, Typesafe Play framework
 Great resources on the Azure Blog. Just search “java”
– http://azure.microsoft.com/blog/?s=java
