Java REST API Comparison: Micronaut, Quarkus, and Spring Boot - jconf.dev 2020Matt Raible
"Use Spring Boot! No, use Micronaut!! Nooooo, Quarkus is the best!!!"
There's a lot of developers praising the hottest, and fastest, Java REST frameworks: Micronaut, Quarkus, and Spring Boot. In this session, you'll learn how to do the following with each framework:
✅ Build a REST API
✅ Secure your API with OAuth 2.0
✅ Optimize for production with Docker and GraalVM
I'll also share some performance numbers and pretty graphs to compare community metrics.

The Digital Decoupling Journey | John Kriter, AccentureHostedbyConfluent
As many organization seek to modify both their core business technology platform, and their outlying digital channels, one of the largest hinderances people talk about is core data access. As one of our chief partners in event/stream processing, Confluent has worked with Accenture in the creation of our Digital Decoupling strategy. Leveraging CDC technologies to allow data access without modifying the core, organizations are now able to easily access data they previously would struggle to marshal. And not only data access, but real time responses and interactions with customer data previously locked behind the walls of antique or mission-critical systems.

Composable Software Architecture with SpringSam Brannen
What does the architecture of a modern enterprise Java application look like? What have we as a community learned from our past? What does it mean to design a composable architecture? And how can Spring help developers meet the needs of enterprise applications in 2013 and beyond?
In this keynote presentation at Java Breeze, core Spring Framework committer Sam Brannen invites the audience to explore what it means to design, develop, and test modern enterprise Java applications following a composable software architecture model. Along the way, Sam will show how the Spring ecosystem and programming model fit into the larger picture of modern enterprise Java applications.

What does being "cloud native" mean? In this session, presented at the Austin Microservices Meetup, I explore the four levels of the ODCA Cloud Application Maturity Model and discuss how microservices and containers can help transform applications.
Slides from QConSF Nov 19th, 2011 focusing this time on describing the globally distributed and scaled industrial strength Java Platform as a Service that Netflix has built and run on top of AWS and Cassandra. Parts of that platform are being released as open source - Curator, Priam and Astyanax.
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.
MEAN Stack is a full-stack JavaScript solution that helps you build fast, robust and maintainable production web applications using MongoDB, Express, AngularJS, and Node.js.
Where SOA and Monolitch EAR have failed. It's not simple to have your Apps scaling automagically without a very complex architecture. We're going to show pros and cons of so called Cloud-Native Applications based on Microservices, Caas, DevOps, Continuous Delivery....
MERN is one of several MEAN stack (MongoDB Express Angular Node) variants in which the traditional Angular.js frontend framework is replaced with React.js. MEVN (MongoDB, Express, Vue, Node) is another variant, and really any frontend JavaScript framework can work.Node.js is a popular and powerful JavaScript server platform, and Express.js is a server-side web framework. Regardless of which variant you choose, ME(RVA)N is the best way to work with JavaScript and JSON from start to finish.
DURATION:60 days
In this session, we will learn what are observables and how we work with them in Angular - creating them and subscribing to them.And how we can deliver messages between different parts of your single-page application.
This webinar gives a brief introduction to the OpenStack cloud, covering the topics:
- the OpenStack cloud platform,
- the Open Source community,
- OpenStack architecture and its main elements,
- overview of the compute, networking, block-storage e object-storage services.

4. Threads (deamon,non-deamon)
• Daemon thread JVM’nin kendi içerisinde garbage collection (çöp toplama)
gibi amaçlar için kullanılır
• Non-daemon thread ise bizim programımızda çalışan threadlerdir
5. JVM’e yüklenen
classların
Meta datalarını
Tutar. Perm gen
Memorynin
Bir parçasıdır.
JVM Block Diagram
Threadler çalışırken
kullanılan class
instancelerinin
tutulduğu alan
Threadlerlerin
method invocationlarında
Kullandıkları
geçici memory alanı
6. Heap Nedir?
• Java Heap JVM tarafından oluşturulur ve çeşitli hafıza
alanlarından oluşur
• Eden – new operatörü ile oluşturulan tüm nesneler önce bu hafıza
alanında oluşturulur.
• Survivor – nesneler old heap hafıza alanına transfer edilmeden
önce bir müddet survivor hafıza alanlarında kalır. Buradaki amaç
kısa ömürlü olan nesnelerin Garbage Collector tarafından
toplanmasına ve old heap alanına geçmelerini engellemektir.
• Old – uzun ömürlü nesnelerin ölene kadar kaldıkları hazıfa alanıdır.
• Permanent – sınıfların ve statik değerlerin yer aldığı hazıfa alanıdir.
JVM’in ihtiyacı olan metadatayı tutar. Heap memorynin bir parçası
değildir. Perm gen objeler full gc yapıldığında temizlenir.
7. JVM Memory Parametreleri
Switch Description
-Xms Sets the initial heap size for when the JVM starts.
-Xmx Sets the maximum heap size.
-Xmn Sets the size of theYoung Generation.
-XX:PermSize Sets the starting size of the Permanent Generation.
-XX:MaxPermSize
Sets the maximum size of the Permanent
Generation
8.
9. Stack Nedir?
• Metodlar , metodlara gönderdiğimiz
parametreler , local primitive tipler
ve local referanslar(object
referance) bulunur
• Eğer primitive değişken class
içerisindeyse Heap memory
de, metod
içerisindeyse Stackmemory de
tutulur
10. Her threadin kendine ait stack alanı vardır.
Bir method çağrıldığında oluşan geçici datalar bir stack frame içinde tutulur
11. Garbage Collection
• Farklı JVM implementasyonları için farklı teknikler kullanır, standart bir tanımı
yoktur
• Temel görevi kullanimi son bulmus, hiçbir nesne örnegi tarafindan referans
gösterilmeyen, bellek bölgelerini tesipit edip o bölgelerdeki bellek alanini
bosaltmaktir
• Eğer kullanılmayan nesneler tespit edilip boşaltamazsa memory leak(bellek sızıntısı
oluşur)
• GC’nin ne zaman calisacagi JVM’in kontrolundedir
