    Speaker: Jared Stehler

    Once an API is released to production and entrenched in the core business, it can be difficult to modernize over time. In this talk, we'll dive into the techniques and supporting software we developed which allowed us to transition seamlessly from a high-traffic legacy python API to a new one written completely in Java. We'll cover how we created tooling and a visual interface for detecting and exploring output differences, segmented traffic to roll out gradually, and introduced canary deployments to ensure safer deployments.

    MeetUp Registration: Creating Resilient Micro-Services.


    The foundation of Application Resiliency is often found in the application code where Fault Tolerance is baked into the application at the time of designing and coding….

    This presentation starts with building resiliency ground-up by baking the basic crucial patterns into the application. Resiliency4j provides the out of the box integration with Spring Boot, a defacto standard micro-service framework.

    The patterns discussed include:

    • Rate Limiter
    • Retry
    • Bulkhead
    • Circuit Breaker
    • Timeouts
    • Distilling Java Containers

    Three evolutionary ecosystems work well together: Java, Containers, and Kubernetes. Past versions of Java were never designed to be "container aware." This has led some to stray from the JVM to consider other shiny languages for Containers.

    But wait, let’s discover what Java 9, 10, 11, 12, 13 (…) has done to get our applications into efficiently distilled containers that pack nicely into Kubernetes.
