Agenda● High-level intro to MicroProfile (15 minutes) (Martin)● High-level intro to Quarkus (5 minutes) (Karm)● Demo of MP Starter: (15 minutes) (Karm)● Demo of MP Starter REST API (5 minutes) (Karm)● More MicroProfile specs and Q&A (Martin, Karm)

Enterprise Java in past 20 years● Java EE (currently Jakarta EE)

○ Java EE 5 - May 11, 2006

○ Java EE 6 - December 10, 2009

○ Java EE 7 - June 12, 2013

○ Java EE 8 - August 31, 2017

MicroProfile● Eclipse MicroProfile is an open-source community specification for Enterprise

Java microservices

● A community of individuals, organizations, and vendors collaborating within an open source (Eclipse) project to bring microservices to the Enterprise Java community

And some are In Progress:Quarkus, WildFly...

Differences from Java EE● open source and open community

● code first approach

● release cadence

○ MP 1.0 - Sep 2016○ MP 1.1 - Aug 2017○ MP 1.2 - Sep 2017○ MP 1.3 - Jan 2018○ MP 1.4 / MP 2.0 - Jun 2018○ MP 2.1 - Oct 2018

Differences from Java EE● 3 releases per year (Feb, Jun, Oct)

○ MP 2.2 - Feb 2019○ MP 3.0 - Jun 2019○ MP 3.1 - Oct 2019○ ...

What is MicroProfile Starter● MicroProfile Starter generates working sample code for MicroProfile specifications:

○ To lower the learning curve for using MicroProfile specifications○ To increase developer productivity○ To deliver solutions faster to the business

● A starter/generator had been discussed by the community many times before○ Earliest whisper by James Strachan back at Devoxx BE 2016

● An independent community member, Rudy De Busscher, on Aug 21, 2018, attended the bi-weekly MicroProfile community Hangout call and demoed a prototype that he had developed - (Rudy was hired by Payara subsequently)

● Starter team was assembled soon after. Starter Beta released on Feb 6, 2019.● Current team members are from many organizations and communities: Rudy, Karm, YK, Ryan,

etc.● If you’d like to participate and help us develop the Starter, please post your desire to help us at

microprofile@googlegroups.com to get you looped in○ Need help developing extensions for IntelliJ IDEA, Eclipse IDE, Netbeans, Eclipse Che

● Examples generator for a variety of runtimes

● This is NOT just a pom.xml generator

● Sports REST API for easier integration

● Best for your first contact with MicroProfile, using your favourite runtime you are used to

❤ How to contribute ❤

15

● Runtimes implementations○ Adding your MP implementation - ensure it passes the MP

TCKs for the umbrella release and is added to the MP implementations page

○ Improving current runtimes implementations. Are you a Launcher or KumuluzEE fan? Helidon expert? Take a look...

● Contribute to develop more code examples for MP specs○ Follow these instructions○ Do a Pull Request on the Starter project○ Add your implementation or new code examples○ Test your additions to the MicroProfile starter project○ Community review, requires 2 acks○ Merge

What is Quarkus?● A Kubernetes Native Java stack tailored for GraalVM & OpenJDK HotSpot,

crafted from the best of breed Java libraries and standards

● Great interoperability with containers, small memory footprint

● Toolchain for building Java applications with a lot of heavy lifting done at build time instead of runtime

Eclipse Vert.x Hibernate RESTEasy Apache Camel Eclipse MicroProfile Netty

Kubernetes OpenShift Jaeger Prometheus Apache Kafka Infinispan

Best of breed frameworks and standards

For a complete list of supported extensions: https://github.com/quarkusio/quarkus/tree/master/extensions

A cohesive platform for optimized developer joy:

● Based on standards, but not limited

● Unified configuration

● Zero config, live reload in the blink of an eye

● Streamlined code for the 80% common

usages, flexible for the 20%

● No hassle native executable generation

Build / Dev / Native modes● You can use Quarkus to build a small uberjar

○ https://quarkus.io/guides/maven-tooling.html#uber-jar-maven○ Use HotSpot or GraalVM to to run it

● You can work in Dev mode○ where Quarkus monitors your changed files, quickly recompiles○ enables hot deployment with background compilation○ https://quarkus.io/guides/maven-tooling.html#development-mode

● You can use Quarkus to easily create a single statically linked executable○ Leverages SubstrateVM and Native image from GraalVM toolchain○ Single executable for particular architecture○ https://quarkus.io/guides/building-native-image-guide
