Cloud-native Java for this decade with Quarkus

Enterprise Java has come a long way. What does a modern development approach look like, in the age of Jakarta EE and MicroProfile APIs?

In this session, we’ll have a look at supersonic, subatomic Java with Quarkus. If you’re familiar with enterprise development with Spring or Java EE, you’ll be delighted to see the effective way of working, Quarkus enables. We’ll see the benefits of Quarkus for modern, cloud-native microservices in the year 2020. Get yourself ready for this live-coding-only session!

Make your microservices as much robust as mission critical systems by MicroProfile and Jakarta EE

Kenji Kazumura (Fujitsu Limited)

One of the most important things when building microservices for the enterprise mission critical systems
is high reliability. Even if a new deployed service has a bug,
it is required that the other services should not be affected by this bad service.
This session will provide how to build such a robust system with MicroProfile functions such as
Fault Tolerance, Metrics, and OpenTracing.
Although there are a lot of tuning knobs in Fault Tolerance (timeout, circuitbreaker, retry, fallback, and so on),

Why Jakarta EE Matters Today

Ryan Cuprak (Dassault Systemes)

Werner Keil (Self Employed)

Jakarta EE is now over 20 years old and despite its age, it is as relevant today as it was back in 1999. It is one of the few open standards for developing enterprise applications with multiple independent vendor implementations. Its APIs are central to developing Java based cloud solutions. It is as relevant today as it was back in 1999. Most Java developers, even if they don’t consider themselves “EE” developers, use these technologies every day and their resumes are an alphabet soup of Jakarta EE specifications.

Participating in Jakarta EE

Ryan Cuprak (Dassault Systemes)

It has never been easier to participate in the evolution of Java EE/Jakarta EE. This presentation will provide you with a roadmap and the steps necessary to begin contributing. It isn’t complicated and doesn’t require a lawyer! Unlike proprietary technologies which have come and gone, you can participate in Jakarta EE and help determine the course of your career and improve the technologies for your business or employer.

From Java EE to cloud-native

Jean-François James (Worldline)

For 2 decades, Java EE has been the reference programming model for enterprise applications. With the rise of the cloud, started by Amazon in 2006, the IT landscape has changed and application needs have evolved in terms of architecture, scalability model, observability...

Should we throw away our good old Java EE applications? Are they able to evolve in this new context? How to make them cloud-ready or even better cloud-native? Do we need to switch to another technology?

Application servers and cloud-native applications: match or mismatch?

Jean-François James (Worldline)

Over the years Java application servers have acquired a bad reputation among developers:

Tedious and error-prone development cycle
Painful testing
Slow startup time
Heavy system footprint.

In a nutshell: not productive enough and too heavy for modern cloud-native applications!

But is this bad reputation still relevant today? What about modern application servers and frameworks such as OpenLiberty, WidlFly, Quarkus, Payara, KumuluzEE and TomEE? Are they ready for this new cloud-native world?

Optimize your applications to the max with Jakarta EE and MicroProfile

Edwin Derks (Ordina JTech)

Jakarta EE’s programming model and application server runtimes are a modern approach for developing Java-based enterprise applications. Especially when complemented with Eclipse MicroProfile and supporting tools, these fit perfectly in containers and scalable infrastructures. In this talk, I will explain how to tailor and optimise such enterprise applications to the max in order to achieve optimal value and development experience. In addition, I will compare some key concepts with competitors like Spring Framework.

Pragmatic Microservices in Kubernetes with MicroProfile

Ondrej Mihalyi (Payara Services Limited)

This tutorial explains how to design applications to effectively develop them with the Microservices architecture. It examines building microservices step by step, how to design boundaries between components using Domain-driven design and when to split a microservice into smaller services.

Cloud-ready apps effectively with MicroProfile

Ondrej Mihalyi (Payara Services Limited)

This live coding session shows how to design Jakarta EE applications to effectively develop them with the Microservices architecture. From a simple Jakarta EE service, we'll evolve our code using MicroProfile to build a scalable system with very few code changes and no code waste.

You'll see how to focus on business logic and application design, and not to worry about the technology or cloud. With Jakarta EE and MicroProfile, it's very easy to evolve your codebase to scale it and run in the cloud in the future.
