Micronaut: A new way to build microservicesLuram Archanjo
Over the years microservices architecture has been widely adopted in conjunction with Spring Boot. But recently, we are witnessing the rise of microframeworks such as Micronaut, which has innovated the way we build microservices by providing low memory consumption, fast startup, non-blocking, and other important features that I will demonstrate and conceptualize in this talk.
Cloud Native Night June 2019, Munich: Talk by Moritz Kammerer (Software Architect at QAware)
Join our Meetup: www.meetup.com/cloud-native-muc
Abstract: Startup-Zeiten von Containern werden bei elastischer Skalierung in der Cloud immer wichtiger – wer möchte schon 2 Minuten warten, bis eine neue Instanz des Services erscheint? Hier kann der Shooting Star von Java-basierten Microservices, Spring Boot, nicht glänzen. Systembedingt steigt die Startzeit des Containers mit der Menge der Klassen auf dem Classpath. Auch der Speicherverbrauch einer Spring Boot Anwendung ist nicht gerade gering.
Micronaut, erschaffen von den Machern des Grails-Frameworks, behauptet, diese Probleme in den Griff zu bekommen. In dem Talk sehen wir uns an, wie sich Microservices mit Micronaut entwickeln lassen und prüfen, ob es die Versprechen hält.
Bonus: Da Micronaut kaum Reflection verwendet, sollte es sich mit dem GraalVM AOT Compiler in ein natives Image kompilieren lassen. In dem Vortrag werden wir dies ausprobieren und die Performance dieses Native Images messen.
Discussed the capabilities, advantages and disadvantages of Keycloak, made a basic understanding of how it can be applied and integrated into various systems.

Reactive Java Microservices with Spring Boot and JHipster - Spring I/O 2022Matt Raible
Microservice architectures are all the rage in JavaLand. They allow teams to develop services independently and deploy autonomously.
Why microservices?
IF
you are developing a large/complex application
AND
you need to deliver it rapidly, frequently, and reliably over a long period of time
THEN
the Microservice Architecture is often a good choice.
Reactive architectures are becoming increasingly popular for organizations that need to do more, with less hardware. Reactive programming allows you to build systems that are resilient to high load.
In this session, I'll show you how to use JHipster to create a reactive microservices architecture with Spring Boot, Spring Cloud, Keycloak, and run it all in Docker. You will leave with the know-how to create your own resilient apps!

Node.js BFFs: our way to better/micro frontendsEugene Fidelin
About 2 years ago Marktplaats.nl started to build a new platform. We migrated from huge Java-based frontends towards smaller Node.js BFFs (backend-for-frontends). We are close to the next step and adapt a micro-frontends approach.
Here I would like to share the outcomes of this quest: what architecture solutions are made, how does Marktplaats.nl run and scale so many BFFs in production, how we grew as a team, educated frontend-developers to write backend code and what were our biggest challenges.

This is your one stop shop introduction to get oriented to the world of reactive programming. There are lots of such intros out there even manifestos. We hope this is the one where you don't get lost and it makes sense. Get a definition of what "reactive" means and why it matters. Learn about Reactive Streams and Reactive Extensions and the emerging ecosystem around them. Get a sense for what going reactive means for the programming model. See lots of hands-on demos introducing the basic concepts in composition libraries using RxJava and Reactor.
GraphQL is a query language for APIs and a runtime for fulfilling those queries. It gives clients the power to ask for exactly what they need, which makes it a great fit for modern web and mobile apps. In this talk, we explain why GraphQL was created, introduce you to the syntax and behavior, and then show how to use it to build powerful APIs for your data. We will also introduce you to AWS AppSync, a GraphQL-powered serverless backend for apps, which you can use to host GraphQL APIs and also add real-time and offline capabilities to your web and mobile apps. You can follow along if you have an AWS account – no GraphQL experience required!

An introduction to reactive programming concepts and basics. I aim here to show what's reactive programming, why it's used and show some frameworks and benchmarks that support it.
Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
Back in 2015, Square and Google collaborated to launch gRPC, an open source RPC framework backed by protocol buffers and HTTP/2, based on real-world experiences operating microservices at scale. If you build microservices, you will be interested in gRPC.
This webcast covers:
- a technical overview of gRPC
- use cases and applicability in your stack
- a deep dive into the practicalities of operationalizing gRPC
Some security problems can be eliminated by using web components, others at least reduced, but you have to take specific actions or you won't get the benefits.

Mark Stoodley examines some of the strengths and weaknesses of the different Java compilation technologies, if one was to apply them in isolation. Stoodley discusses how production JVMs are assembling a combination of these tools that work together to provide excellent performance across the large spectrum of applications written in Java and JVM based languages. Filmed at qconsf.com.
Mark Stoodley joined IBM Canada to build Java JIT compilers for production use and led the team that delivered AOT compilation in the IBM SDK for Java 6. He spent the last five years leading the effort to open source nearly 4.3 million lines of source code from the IBM J9 Java Virtual Machine to create the two open source projects Eclipse OMR and Eclipse OpenJ9, and now co-leads both projects.

Simple tweaks to get the most out of your jvmJamie Coleman
Many developers don’t think about the JVM level when creating applications. It is something that just simply works. Now more applications are becoming cloud-native and we have JVM’s running in every microservice container, each performance gain can have massive benefits when scaled up. Some tweaks are very easy to implement and can have huge impacts on start-up time and performance of your applications. This talk will go through all the different JVM options and give you some easy and simple advice on how to get the most out of your JVM to save not only money but also energy on the cloud.

(java2days) Is the Future of Java Cloudy?Steve Poole
Java – it’s on billions of devices. We think it powers the world. Others disagree.
In this talk we’ll examine a few of the reasons why some developers believe Java is being left behind by younger (or at least different) programming languages. We’ll show where the claims make sense and debunk some of the more outrageous slander. We know the future of Java includes a more polyglot world so we’ll help you understand with practical advice where Java shines today and where you might be better using something else. We’ll also cover the challenges that all runtimes have in the new era of Cloud and how the Java community is leading the way in evolving Java into becoming the Cloud runtime of choice.
This talk will help you become more informed when dealing with those inevitable language cage fights around the water cooler. You’ll be able to refute the fake news and replace it with clear facts. Vote for Java – you know it makes sense

Paketo Buildpacks : la meilleure façon de construire des images OCI? DevopsDa...Anthony Dahanne
Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ?
Venez le découvrir lors de cette session ignite
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
2. About Me
• Graeme Rocher
• Creator of Grails and Micronaut
• Principal Engineer at Object Computing
• Oracle Groundbreaker Award Winner
• Based in Pais Vasco
3. Agenda
• Challenges Facing Java and Software in General
• Microservces and Serverless vs. Traditional Models
• Micronaut Demos!
• Q & A!
4. Serverless
Challenges
• Challenges to using Java in
Serverless / Microservices scenarios
• Existing Tools and Frameworks Not
Optimized for Cold Starts / Low
Memory
• Go, Node etc. better in this regards
• Tim Bray (Amazon/AWS) and others
not recommending Java
https://youtu.be/IPOvrK3S3gQ?t=1109
5. Adapting to Serverless
• Optimize for cold starts
• Forget about connection pools
• Don't bother with local caches
• Choose technology based on your cold start requirements
6. Adapting to
Microservices
• Cold starts less important, but still
important
• The Container is the deployment
unit
• Containers and Java require special
memory management
• Optimization for memory usage
required
7. Traditional Frameworks
Spring is an amazing technical achievement and does so many
things, but does them at runtime.
• Reads the byte code of every bean it finds
• Synthesizes new annotations for each annotation on each
bean method, constructor, field etc. to support Annotation
metadata
• Builds Reflective Metadata for each bean for every method,
constructor, field etc.
8. What to do, What to
do?
1. Tough technology decisions ahead
2. Choose appropriately tool for the
job
3. Traditional frameworks often not the
best choice
9. The Micro Reality
• Frameworks based on reflection
and annotations become fat
• But we love the programming
model and productivity so
we live with it
• So ... why should we be
more efficient?
10.
11.
12. Java's Problems for
Frameworks
• Limited Annotation API
• Type Erasure
• Slow Reflection
• Reflective Data Caches
• Classpath Scanning
• Slow Dynamic Class Loading
15. Why is Reflection a Problem?
• Today the JDK is OpenJDK!
• Just take a look...
http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/687fd7c7986d/src/
share/classes/java/lang/Class.java#l2471
• All Reflective data initialized on first access and held in soft
references (yes every field, method etc.)
• Won't be GC'ed until your application is low on memory!
16. Java's "Problems"
• Greatly Exaggerated (Java has been
dead forever)
• Java can be Fast! (see Android and
Micronaut)
• However Most Existing Tools are
based around
• Reflection
• Runtime Proxies
• Runtime Byte Code Generation
(bytebuddy/cglib/javassist)
17. Java's Advantages
• Mature, Robust Ecosystem
• Outstanding IDEs
• Code Maintenance and Refactoring
• Developer Availability
• Build System Maturity
• Diversity (Mobile, IoT, Server Side)
• Languages (Java, Kotlin, Groovy,
Scala)
18. By the time Go has all
the features of Java,
Java's startup
performance will
match Go
19. Already Solved
Problem
• The Android Community already
solved the problem
• Ahead of Time Compilation used
extensively
• Google Dagger 2.x
• Compile Time Dependency
Injector
• Reflection Free
• Limited in Scope to just DI
20. Ahead of Time
Compilation
• So what is Ahead of Time (AOT)
compilation?
• Pre-computation of application code
using closed world static analysis
• Fancy way of saying do more at
compilation time
and less at runtime
21.
22. Micronaut is...
• A Microservices and Serverless
Focused framework (hence the
branding)
• Also a Complete Application
Framework for any type of
Application
• Dependency Injection, Aspect
Oriented Programming (AOP),
Configuration Management,
Bean Introspection and more..
23. Micronaut AOT
Computation
• All Dependency & Configuration
Injection
• Annotation Metadata (Meta
annotations)
• AOP Proxies
• Essentially all framework
infrastructure
• ie. What Spring/CDI do at runtime
24. With Micronaut You
Can Build
• Microservices
• Serverless Applications
• Message-Driven Applications with
Kafka/Rabbit
• CLI Applications
• Even Android Applications
• Anything with
static void main(String..args)
25. So What is
Micronaut? Really?
• An Application Framework for the
Future
• Reflection Free, Runtime Proxy Free,
No Dynamic Classloading
• Ahead of Time (AOT) Compilation
AOT APIs
• ... oh and let's you build
Microservices
26. Micronaut's Impact
• We announced Micronaut on March
2018
• Open Sourced 28th of May 2018 (a
year ago!)
• Sparked industry wide
improvements from Red Hat (with
Quarkus) and Pivotal (Spring Boot
2.2)
• Micronaut is changing the face of
server side Java
27. GraalVM
• A New Universal Virtual Machine
from Oracle
• Features a native-image Tool
• Converts Java -> native machine
code using AOT
• Works well with Micronaut
• Startup time 20ms and Memory
Consumption 18MB!
http://www.graalvm.org
30. How Small?
• Smallest Micronaut Hello World JAR is 12MB when written
Java or 14MB in Groovy
• Can be run with as little as 10mb Max Heap with Kotlin or
Java (20mb for Groovy)
• Startup time subsecond for Kotlin or Java (a little more for
Groovy)
• All Dependency Injection, AOP and Proxy generation
happens at compile time
32. Micronaut AWS Lambda
Cold Starts
Style Cold Start
Simple Function +/- 300ms
API Gateway +/- 800ms
API Gateway + Graal Custom
Runtime
+/- 150ms
33. Micronaut 1.1 Out
Now and
Production-Ready
• Compile Time DI & AOP
• HTTP Client & Server
• GRPC and GraphQL Support
• RabbitMQ and Improved Kafka
Support
• Micronaut 1.1.2 supports GraalVM
19 native (experimental status)
34. Micronaut project is
healthy
• ~2 years of development by several
OCI engineers.
• 128 contributors (19 from OCI).
• ~2350 stars on GitHub.
• ~6000 commits.
• More Exciting Announcements in
2019
• Made in Spain (partly ;-)
36. Summary
• Micronaut and GraalVM are leading the AOT revolution
• Server Side Java is Adapting to the Serverless world
• Building more efficient applications possible with right
framework choices
• AOT Sacrifices Compilation Speed to Gain so Much More
• Going native an option for the future with GraalVM
