Rafael del Nero

Java Champion, Senior Software Engineer at Mastercard

It's gonna be intense interactive session!

Rafael will ask you what is the answer from the code puzzle.

The session is basically core Java concepts from Java 8 to Java 19.

And, accordingly, a Java puzzle for each version.

Join in and solve it.

Lead Engineer at Form3, Founder at Yon Labs

Do you want to see live Kubernetes hacking? Come to see interactive demos where your newly registered accounts in a k8s application are hijacked.

This talk guides you through various security risks of Kubernetes, focusing on OWASP Kubernetes Top 10 list. In live demos, you will find out how to exploit a range of vulnerabilities or misconfigurations in your k8s clusters, attacking containers, pods, network, or k8s components, leading to an ultimate compromise of user accounts in an exemplary web application.

You will learn about common mistakes and vulnerabilities along with the best practices for hardening your Kubernetes systems.

Head of development at ip.labs Bonn

In this talk I will talk about 2 AWS Services which aim at increasing the productivity of Java developers on AWS: Amazon CodeGuru and CodeWhisperer. We'll go through some practical examples and build and analyze the AWS Serverless application with the help of these services.

Amazon CodeGuru Reviewer uses ML and automated reasoning to provide recommendations to developers on how to fix issues to improve code quality and dramatically reduce the time it takes to fix bugs before they reach customer-facing applications and result in a bad experience. 

Amazon CodeWhisperer is the machine learning-powered services that help improve developer productivity by generating code recommendations based on developers’ comments in natural language and their code. Based on natural language comments, these services also automatically recommend unit test code that matches your implementation code.

Solutions Architect at Nortal, Java Champion

Java is innovative with each release, and to become a creative engineer for your company, you should know what is new in your language. This session will sweep the dust off Java SE's 20 hidden gems, including new cool language features, compiler changes, library additions, and critical bug fixes. They're handy in your day-to-day work.

Mark Heckler

Principal Cloud Advocate, Java/JVM Languages at Microsoft

So-called "serverless" may be the least accurate tech name in history, although there are countless worthy contenders for that (dis)honor. And while functions may not have a perfectly precise definition in terms of size or scope, we're far more likely to reach general agreement on functions - their purpose, scope, pros/cons, and utility - than we are to ever locate those missing servers. :)

In this session, the presenter examines what makes a capability or set of capabilities ideal candidate(s) for development and deployment as one or more functions. The presenter will then lead attendees on a Live Coding Adventure(TM) to demonstrate how to create candidate functions using the power of Spring Boot and Spring Cloud Function. Finally, we will deploy these open source functions via Azure Functions to demonstrate how to integrate everything in the cloud and reveal some potentially very welcome discoveries. Come to this session to learn how to incorporate functions into your critical systems. With great power...

Mary Grygleski

Streaming Developer Advocate at DataStax

The world is moving at an unprecedented pace and much of it has been powered by the innovations in software and systems. While event handling, messaging, and processing are not necessarily brand new concepts, the recent emergence in hardware such as virtualizations, multi-core processors, and so on, are in fact pushing the envelope in software design and development, elevating it to higher levels of capabilities never seen before. In the case of streaming which very often leverages on the underlying messaging mechanism(s) to bring distributed messaging to higher forms of purposes, such as IoT/IIoT applications, AI/ML data pipelines, or even eCommerce recommendations, event streaming platform has indeed become the “glue” in enabling data to flow through disparate systems in the pipeline and in a very dynamic fashion.
‍
This talk on event streaming is meant for anyone interested in learning about it, and understanding how it fits into the modern software development design and architecture, as well as seeing some of the challenges it faces especially in the Cloud Native environment. We’ll then take a look at an open source platform - Apache Pulsar, which is poised to become the de facto new generation of distributed messaging and streaming platform that will bring joy to developers, and enable systems and applications to be highly responsive with its true real-time capabilities.

Monica Beckwith

Java and JVM Performance Architect at Microsoft

Managed runtime performance expert, Monica Beckwith will divulge her survival guide which is essential for any JVM based application performance engineer to get to the bottom of a performance issue. The presentation will provide a step-by-step approach to finding system-wide performance and scalability bottlenecks. Monica will walk the attendees through an example that will showcase a few performance tools and the performance process. Following the simple rules highlighted in the presentation and applying performance engineering patterns will make you and your stakeholders happy.

Richard Davison

Sr. Partner Solutions Architect - Application Modernization

Microservice architecture deployed to function as a service infrastructure allows you to closely align capacity to usage, allowing you to scale up and down with ease. However when you use JVM languages the JIT warm-up time can introduce additional latency which sometimes limits which workloads this approach is suitable for.

In this talk you will learn how snapshotting of Java Lambda functions is changing this entirely. You will learn how you can create a snapshot of your function after JIT compilation has been completed. So that subsequent scale ups are much faster. The talk will discuss best practices, example applications and additional resources.
