  • Go Native with Spring Boot and GraalVM

    Spring Boot 3 & Spring Framework 6, due in late 2022, will have built-in support for native Java. For Spring Framework 5.x & Spring Boot 2.x, Spring Native is the way to go. Spring Native provides integrations for Spring's vast ecosystem of libraries. It also has a component model that allows you to extend native compilation support for other libraries.

  • Article Series: Native Compilations Boosts Java

    Java dominates enterprise applications. But in the cloud, Java is more expensive than some competitors. Native compilation makes Java in the cloud cheaper. It raises many questions for all Java users: How does native Java change development? When should we switch to native Java? When should we not? And what framework should we use for native Java? This series provides answers to these questions.

  • Cloud Native Java with the Micronaut Framework

    The Micronaut framework provides a solid foundation for building Cloud Native Java microservices. It reduces the use of Java reflection, runtime proxy generation, and dynamic classloading. Tight integration with GraalVM Ahead-of-Time Compilation (AOT) has seen the usage of the Micronaut framework grow.  Active compilation-time checking increases type safety and improves developer productivity.

  • Getting Started to Quarkus Reactive Messaging with Apache Kafka

    How data is processed/consumed nowadays is different from how it was once practiced. In the past, data was stored in a database and it was batch processed for analytics. Apache Kafka is a distributed event store and stream-processing platform for storing, consuming, and processing data streams in real-time. In this post, we’ll learn how to produce and consume data using Apache Kafka and Quarkus.

  • Designing Secure Tenant Isolation in Python for Serverless Apps

    Software as a Service (SaaS) has become a very common way to deliver software today. While providing the benefits of easy access to users without the overhead of having to manage the operations themselves, this flips the paradigm and places the responsibility on software providers for maintaining ironclad SLAs, as well as all of the security and data privacy requirements.

  • Native Java in the Real World

    Microservices on Kubernetes are the native Java sweet spot: they have the most significant framework and Java runtime overhead. Native Java needs more effort to build, debug, test, deploy & profile. The application framework should fully support native Java in production. Native Java adoption can be incremental. But a native Java application only works if all its libraries support native Java.

  • Kubernetes Native Java with Quarkus

    Quarkus is an industry leader in startup time and memory utilization for native and JVM-based Java applications. This reduces cloud costs. Kubernetes is a first-class deployment platform in Quarkus with support for its primitives and features. Developers can use their Java knowledge of APIs like Jakarta EE, MicroProfile, Spring, etc. Applications can be imperative or reactive - or both!

  • Revolutionizing Java with GraalVM Native Image

    GraalVM Native Image is an ahead-of-time compiler that generates native Java executables. These executables start very fast and use less CPU and memory. This makes Java in the cloud cheaper. GraalVM can even achieve peak throughput on par with the JVM. Many Java frameworks already support GraalVM, such as Spring Boot, Micronaut, Quarkus, Gluon, etc.

  • Two Must-Have Tools for Jakarta EE Developers

    The wildfly-jar-maven-plugin and the brand new wildfly-datasources-preview-galleon-pack from the WildFly project are worthy of your attention. These tools add on-the-fly generation of an Uber JAR including configuration for containerization and datasources, and make it a pleasure to write applications for Jakarta EE and WildFly.

  • A Standardized, Specification-Driven API Lifecycle

    At QCon Plus last November, Kin Lane, Chief Evangelist with Postman, and the Open Technologies Team lead presented on API specifications. API specifications are essential to him and at Postman. So he wanted to share a bit of how they see API specifications impacting how they produce and consume APIs.

  • Level up Your Java Performance with TornadoVM

    GPUs, FPGAs, or multi-core CPUs are present in almost every computing system today. These devices help increase performance and run more efficient workloads, but most frameworks are built on C or C++ only. At QCon Plus, Juan Fumero spoke about TornadoVM, a high-performance computing platform for the JVM, allowing to offload, at runtime, Java code to run on heterogeneous hardware accelerators.

  • How to Create a Network Proxy Using Stream Processor Pipy

    In this article we are going to introduce Pipy, an open-source cloud-native network stream processor. After describing its modular design, we will see how to rapidly build a high-performance network proxy to serve our specific needs. Pipy has been battle-tested and is already in use by multiple commercial clients.
