Agenda

The Java platform is over twenty-six years old and has reached its 17th release, yet, according to developer surveys, it is consistently in the top three most popular languages.

How is this possible?

In this presentation, we’ll explore how Java has adapted to changing application demands, new development patterns, and keeping the competition at bay.

What features does Java have now that continue to give it appeal for new application development?  How does the JVM deliver better scalability and performance than other platforms?  Where does Java go from here?  These and other questions will all be answered.

This session aims at sharing insights on Azure pipeline templates which are a powerful way to scale your CI/CD flow throughout your organisation. At ING this is achieved with Azure DevOps templates (which some think of as Java classes).

Wouter Ligtenberg and Florin Ioanițescu will reveal how they moved from one different pipeline per team to one single pipeline used by all teams. They will also discuss modularity and flexibility; quality and maintainability; and versioning.

Every six months, we have a new Java release. And to be a practical Java engineer, you should know about what is new in your language. This session will sweep the dust over Java SE 16 hidden gems, including new cool language features, compiler changes, library additions, and critical bug fixes. We’re going to look at here are all reasonably tremendous & they’re handy in your day-to-day work. Let’s take a features tour powered by code about Java 16 and future Java 17 LTS.

Coexisting in large enterprise platforms, APIs often need to fetch from other APIs only the fields they actually use, to reduce the number of queries for performance or to ensure reduction of impact if the dependent APIs evolve.

These are design and technical questions we ask ourselves when we decide the tech stack for a large platform.

We are going to explore several options for this scenario, such as GraphQL and oData, their similarities and differences.

Serverless computing is becoming very popular among developers thanks to Public Cloud and Open Source offerings. Quarkus Funqy is part of the serverless strategy part of Quarkus, a Kubernetes-native Java framework, which aims to provide a portable Java API to write functions deployable to various FaaS environments like AWS Lambda, Azure Functions, Knative, and Knative Events (Cloud Events).
In this session, we will walk through how to write a Java serverless application, and how this framework helps in creating a minimal footprint, eventually native-compiled and Kubernetes-native application which is ready to support modern use cases such as Internet-of-Things or highly- available Cloud deployments.

Simple problems like which is the car that is best for my needs, to more complex ones like what should I invest in, in order to get the best possible results or which departments should receive more funding and why, can all be addressed here. In order to accomplish this a tremendous amount of computations are involved, so we had to be careful when choosing the way we write code but also, the environment we write code in. So which one do you think we choose, Java or Python? Which one of these is best suited to accomplish these kind tasks and how big is the difference between these two? 

Small UseCases with a significant amount of data for internal company usage, most developers had this in their career, already. However, no Ops Team, no Kubernetes, no Cluster is available as part of the solution.

In this talk, I will show a few tech stacks that are helping to deal with persistent data without dealing with the classic horizontal scaling tech monsters like Kubernetes, Hadoop and many more.

Sit down, relax and enjoy the journey through a bunch of lightning-fast persistence alternatives for pure java devs.

If you want to know the magic behind how Spring Boot is preparing everything at runtime before the application starts, this presentation is for you. Learn about Spring Boot Autoconfigure, the component that is preparing all the resource dependencies. See how to integrate your own dependencies automatically into the Spring Boot Context. The live demo will let you see and feel how the Spring Boot Autoconfigure is doing its magic-work.
