More than 15 million Java developers are currently working to realize business requirements and spend a ton of time and effort to optimize the application performance for a variety of workloads (e.g., Web, Mobile, AI/ML, Edge) in the cloud. A big issue for developers is adopting a new programming language or Java runtime due to the lack of compatibility with Kubernetes.

This session will walk you through how developers can scaffold a Java project from scratch and then build it as a Kubernetes Native application that allows you to have a tiny memory footprint and takes milliseconds to start up. You can also continue testing and debugging the application while it’s already deployed to the remote Kubernetes cluster, the same way a local developer experiences the inner loop of development.

In this special session, it's apropos to take on this very different topic at our first in-person meeting since the pandemic! Several members have had questions about what is going on in the employment landscape. From Return to Work to Great Resignations, Quiet Quitting and Tech Layoffs, we'll take a look at what's really behind the confusing and sometimes contradictory employment headlines. Seeing it all from the catbird perspective of a leading Technical Recruiting partner that hires for hundreds of companies, national laboratories, and universities nationwide with data to boot, it should be an evening of insight... and pizza!

In this example-driven session, we're going to look at how to implement GraphQL in Spring. You'll learn how Spring for GraphQL builds upon GraphQL Java, recognize the use-cases that are best suited for GraphQL, and how to build a GraphQL API in Spring.

Typical REST APIs deal in resources. This is fine for many use cases, but it tends to be more rigid and less efficient in others.

For example, in an shopping API, it's important to weigh how much or how little information should be provided in a request for an order resource? Should the order resource contain only order specifics, but no details about the order's line items or the products in those line items? If all relevant details is included in the response, then it's breaking the boundaries of what the resource should offer and is overkill for clients that do not need it. On the other hand, proper factoring of the resource will require that the client make multiple requests to the API to fetch relevant information that they may need.

GraphQL offers a more flexible alternative to REST, setting aside the resource-oriented model and focusing more on what a client needs. Much as how SQL allows for data from multiple tables to be selected and joined in response to a query, GraphQL offers API clients the possibility of tailoring the response to provide all of the information needed and nothing that they do not need.

Most developers are familiar with the concept of unit testing, and how this is useful to ensure validity of your code. Java developers will typically use JUnit to write their unit tests. Many projects use test coverage tools such as Jacoco to ensure that the code as written has tests to validate it. But how strong are the tests? Will they stand up against bugs introduced by future code changes? This talk will cover using PIT to walk through a Java code example to illustrate mutation testing.

In this session, we will show concepts and conventions familiar to Spring developers and how those same
concepts and conventions can be implemented in Quarkus, all while highlighting similarities and differences
between them. Additionally, we will show similarities and differences in how testing is done, highlighting Quarkus
Dev Services.
We will also introduce the Spring compatibility in Quarkus and how to quickly migrate a Spring Boot microservice
application to Quarkus with little-to-no code changes. Time permitting, we may even convert a Spring Boot
microservice into Quarkus, live.

Your project has reached that stage when it's a good idea to post binaries, but new questions appear such as where should they be posted? How do make it easier for users to install and discover your binaries? Where should releases be announced? Most importantly, can answers to these questions be automated? Enter JReleaser, a tool that provides answers to these questions and more.
JReleaser may be used to create GitHub/GitLab/Gitea releases and publish binaries that can be consumed from different distribution channels such as Homebrew, Snap, Scoop, and more. Once published, the release can be automatically announced on Twitter, Slack, Gitter, Discord, and other communication channels.

Don't fear entropy, embrace it.
When you move toward distributed computing the likelihood of failure proportionally increases. It's not your fault, it's simply physics. Once you start spreading your data and applications across more devices, then access to resources such as CPU, memory, and I/O has a higher rate of failure.
Embrace entropy with chaos experiments and increase your cloud native capability model. We'll first investigate how to design Chaos experiments with Java then we'll investigate some of the leading chaos frameworks for Kubernetes and dive into hands-on experiments targeted within blast radiuses.

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.
