AdoptOpenJDK is rapidly becoming a leading provider of OpenJDK™ binaries. With over 25 million downloads in the last year, it is now a serious contender for your production usage of Java™. AdoptOpenJDK provides prebuilt OpenJDK™ binaries from a fully open source set of build scripts and infrastructure. This talk will cover how we build on over 15 different platforms, execute over 60,000 tests and distribute OpenJDK™ binaries to millions of users. We will also cover how AdoptOpenJDK binaries compare against the Java™ binaries that you use today. If you're curious to understand more about our future roadmap, security and supporting platforms like Lego® Mindstorms® then this is the talk for you!

THE NEW ORACLE LICENSE
@gdams_ github.com/gdams linkedin.com/in/gdams

8. ADOPTOPENJDK - AND HOW IT IMPACTS YOU IN 2019
ORACLE JAVA - END OF PUBLIC UPDATES
▸ Oracle are providing free updates for 6 months.
▸ After 6 months you will not get critical fixes for free.
▸ There is some Devil in the Detail:
▸ bit.ly/javaisstillfree

9. PROBABLY NOT
IS THIS A GOOD IDEA?

OPTION 2: GET AN ORACLE SUBSCRIPTION
▸ You’ll get a great JDK/JRE with all the fixes
▸ Pricing at the lower number of JVMs is not punitive!
▸ https://www.oracle.com/java/java-se-subscription.html
@gdams_ github.com/gdams linkedin.com/in/gdams

11. ADOPTOPENJDK - AND HOW IT IMPACTS YOU IN 2019
OPTION 3: CHOOSE AN OPENJDK PROVIDER
▸ RedHat is leading the OpenJDK8 and 11 update projects
▸ Amazon, Azul, Google, IBM, jClarity, SAP supporting
▸ You’ll get a great JDK and JRE with all the fixes
▸ Including “Oracle only” fixes (for now)
▸ You can get binaries that are $free and free to use
▸ But, Commercial support is limited in some cases

31. “GODADDY LIKE MANY COMPANIES NEEDED TO REACT TO THE
CHANGE IN THE JAVA JRE LICENSING AGREEMENT BY ORACLE IN
2018. THE VISION, TEST COVERAGE AND THE CONVENIENCE
FACTOR FOR OUR TEAMS MADE THE TRANSITION FROM
ORACLE’S JAVA BINARIES TO ADOPTOPENJDK BUILT BINARIES
EASY AND OUR EFFORT COMPLETED WITHOUT INCIDENT.”

32. “MOVING TO THE ADOPTOPENJDK DOCKER IMAGES WAS AS EASY
AS YOU'D EXPECT, JUST A ONE-LINE CHANGE WITHIN OUR
DOCKERFILE AND EVERYTHING WORKED FIRST TIME. AFTER
MONTHS OF PRODUCTION USE, WE'VE NOT NOTICED ANY
DIFFERENCES BETWEEN THE ADOPTOPENJDK AND ORACLE
BINARIES. THANK YOU ADOPT FOR MAKING THE MIGRATION AS
SIMPLE AS POSSIBLE.”
