Article Series: Developing Apache Kafka applications on Kubernetes
Apache Kafka has integrations with most of the languages used these days, but in this article series, we cover its integration with Java. In this series, we also discuss how to provision, configure and secure an Apache Kafka cluster on a Kubernetes cluster.

Securing a Kafka Cluster in Kubernetes Using Strimzi
Deploying an Apache Kafka cluster to Kubernetes is easy if you use Strimzi, but that’s only the first step; you need to secure the communication between Kafka and the consumers and producers, provide RBAC to access topics, spread the secrets correctly to Kafka Connect components and all using a Kubernetes GitOps way.

GraalVM Java Compilers Join OpenJDK in 2023, Align with OpenJDK Releases and Processes
The Community Editions of the GraalVM JIT and Ahead-of-Time (AOT) compilers will move to OpenJDK in 2023. They will align with OpenJDK releases and processes. Existing releases, GraalVM Enterprise Edition, and other GraalVM projects will not. GraalVM 22.3 provides experimental support for JDK 19 and improves observability. Project Leyden will standardize Java AOT compilation.

Java Champion Josh Long on Spring Framework 6 and Spring Boot 3
Microservices show where Java lags behind other languages. Reactive programming provides a concise DSL to express the movement of state and to write concurrent, multithreaded code with better scaling. Developing in Spring Boot works well even without special tooling support. Josh Long is excited about Project Loom, Java optimization in Project Leyden, and Foreign-Function access in Project Panama.

Moving Kafka and Debezium to Kubernetes Using Strimzi - the GitOps Way
Deploying an Apache Kafka cluster to a Kubernetes is not an easy task. There are a lot of pieces to configure like the zookeeper, the Kafka cluster, topics, and users. Strimzi is a Kubernetes controller making the deployment process of Kafka a child game. Moreover, Strimzi lets you manage Kafka using GitOps methodology as everything is executed using a Kubernetes YAML file.

Virtual Threads: New Foundations for High-Scale Java Applications
Virtual threads are a lightweight implementation of Java threads, delivered as a preview feature in Java 19. They dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications. Virtual threads breathe new life into the familiar thread-per-request style of programming, allowing it to scale with near-optimal hardware utilization.

Java Champion James Ward on the State of Java and JVM Languages
James Ward is a Java Champion and Google’s Kotlin product manager. In a podcast, Ward agreed that “people are still trapped in the Java world” and called default mutability in Java the “trillion-dollar mistake”. In this interview, he speaks about the state of Java, JVM languages, mutability, and functional programming.
