Eclipse MicroProfile Starter CONFIDENTIAL Designator with Quarkus OpenAlt 2019 Michal Karm Babacek Martin Štefanko @_karm @xstefank Principal Quality Engineer, Red Hat Software Engineer, Red Hat C/Java/Go programmer focused on Apache HTTP Server, Tomcat, load-balancing, MicroProfile committer, Microservices enthusiast high-availability, containers and MicroProfile by day; Coding fluorescence JBoss EAP sustaining engineer microscopy data processing and DNS malware protection toys by night. Avid user JBoss Enterprise Application Platform - application server of Wildfly and Infinispan clustering. Considers 1MB being plenty of memory and WildFly application server - upstream community version of JBoss EAP 16ms plenty of time.

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 4

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 ○ 13

start.microprofile.io ● 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 14

❤ How to contribute ❤ ● 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 15

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 16

Best of breed frameworks and standards Eclipse Vert.x Hibernate RESTEasy Apache Camel Eclipse MicroProfile Netty Kubernetes OpenShift Jaeger Prometheus Apache Kafka Infinispan For a complete list of supported extensions: https://github.com/quarkusio/quarkus/tree/master/extensions 17

Developer joy 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 ● 18

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 ○ 22

And now, on to the demos! 1. Starter web page, examples https://starter.karms.biz/ 2. Downloading Quarkus 3. Your generated examples 4. Other runtimes, Payara, Helidon… 5. REST API 23
