  • Elastic JVM: Configuring G1 GC for Automatic Vertical Memory Scaling

    Nowadays, JVM-based applications can benefit from elasticity and density of container technology. However, there are still some issues that prevent unleashing the full potential of Java and containers “marriage.”

    Releasing unused but committed Heap memory by the major JVM implementations based on OpenJDK, in most cases, is not performed automatically, or requires specific knowledge to be configured.

  • Java Garbage Collection Types and Settings Customization via Jelastic PaaS

  • Building Microservices with Spring Boot Fat (Uber) Jar

    In most minds, microservices is an approach to make a traditional monolithic system more structured, dividing it into logical components that correspond to different functional areas of application.

    Thus, acting as a microservice, each component becomes self-contained, easily scaled, maintained and even upgraded without affecting the overall system.

    Also, with a microservice architecture, you can use a software written in different programming languages, including Java.

    Such freedom attracts but may frighten at the same time.
