• B2GS meetup Launching the Micro Future: Groovy, Grails, and Micronaut With Jeff Scott Brown

    The next B2GS meetup will be October 10 @ 6pm in Waltham:
    Launching the Micro Future: Groovy, Grails, and Micronaut
    With Jeff Scott Brown
    http://meetu.ps/e/FSwgj/1Fnwy/d
    And we will have a zoom meeting.

    While this will be for the Boston Groovy Grails meetup, meaning a screw for our audience, I feel compeled to say that Micronaut can be used form plain Java and Kotlin.

    In this talk, Jeff Brown will demonstrate how the future of Grails, GORM, and Micronaut are linked, as well as how the OCI Groovy and Grails team is taking productivity around developing microservices to the next level!

    Micronaut is a new JVM-based, full-stack framework for building modular, easily testable microservice applications. Unlike reflection-based IoC frameworks, which load and cache reflection data for every single field, method, and constructor in your code, with Micronaut, your application startup time and memory consumption are not bound to the size of your codebase.

    The Micronaut framework shares many core values with Grails, including the enablement of code simplicity and developer productivity. Micronaut offers many additional features for a new class of applications (e.g., microservices, serverless deployments, etc.) that may not be well-suited for Grails.

    Compelling aspects of the Micronaut framework include:
    • Sub-second startup time
    • Tiny processes that may run in as little as 8mb of heap
    • No runtime reflection
    • Dependency injection
    • Load balancing
    • And more!

    • Java is a language in evolution. There are a handful of language changes in Java 9 and 10 plus several JDK changes in 9, 10, 11, and 12. Some of these changes are significant in that they allow us to do things more effectively than before. The difference can be anywhere from reducing code to avoiding errors that come from verbosity. In this presentation we will explore the language changes first. Then we will visit the additions to the JDK. Along the way we will also look at a few things that have been removed from Java as well.

    • You’ve probably heard of MicroProfile, but how do you go from buzz to production? In this code-heavy, interactive presentation, we’ll describe how to use OpenTracing (http://opentracing.io/) with Jaeger (https://www.jaegertracing.io/)  and annotations in MicroProfile and other Microservice architectures to reliably improve and deploy updated versions your applications to OpenShift and Kubernetes in the cloud.  Topics include best practices for performance analysis, maintaining delivery pipelines using the Linux command line, plus tips on the best free OpenTracing tools and SDKs available on GitHub.

       

      NOTE: This meeting is NOT on our normal "second-Thursday" schedule.
