    Speakers: Harris Kirk Craig Lubin

    As Java developers, we have long understood the value of early feedback, unit testing, and Continuous Delivery (CD). As practitioners in a DevOps environment, we tell others how important these practices are. How well do we implement these practices for software intended for DevOps applications? Do we “eat our own dogfood”? In this presentation, I will review an approach taken to apply Continuous Delivery practices with a Java application that creates Jenkins Pipelines.   After hearing the presentation, I hope you will walk away with some ideas on how to implement your Java CD practices in a broader context. 

    Kotlin and Category Theory: Pragmatic Functional Programming 
    by Craig Lubin

    What is Functional Programming (FP) and why should you care? This presentation will provide a simple (but not simplistic) introduction of the science behind both Functional Programming and Category Theory by using simple mathematical concepts and the Kotlin programming language. I will show how to apply these techniques for error handling, IO, and more AND how these techniques can also work in Java (it's not just a "Kotlin thing").
    No prior knowledge of Kotlin or advanced mathematics is required. 

     

     

    Speaker Biography

    Harris Kirk

    Harris Kirk started his passion for computers while completing his MS in Analytical Chemistry. He soon realized programming was way more fun than Chemistry and after a brief stint as a Chemist, he devoted his efforts to writing lab automation systems for pharmaceutical companies. Harris has been having fun (well, usually) in the Java world for over 22 years.  He remembers when there were only 4 Java books in Barnes and Noble. For the last 10 years, he has been developing Continuous Delivery and automation systems in the DevOps landscape using Java, Groovy, Gradle, Maven, Jenkins, Git and another tooling.     
     
    He plays Ultimate Frisbee even in the Boston winters.

  • While "DevOps" is a very overrated and misused marketing term, we have many DevOps stories from around the world proving that shared responsibility between Dev and Ops can work out really well.

    A key component of DevOps is open communication and feedback loops. Monitoring data is one source of these feedback loops. Too often, however, this is only done in Operations for firefighting and root cause analysis. Kevin will discuss approaches of Shifting-Left Performance into the Continuous Delivery Pipeline to give earlier and faster performance, scalability and architectural feedback to developers, testers, architects and business.

    The presentation will include some hands-on experience on how to bake monitoring into DevOps tool chains such as JIRA, Bitbucket, Jenkins, Git, HipChat, JMeter, … - there should be something for everyone who wants to learn some new tips & tricks on how to become more “DevOps’y”

    Kubernetes out of the box is a strong platform for running and coordinating large collections of services, containers, and applications. As is, Kubernetes is powerful for many solutions.

    Remember Underdog?  He was a mild-mannered dog, but when stress and conflict were introduced to the plot he took a magic pill, he became a superhero. Istio is a superhero for Kubernetes.

    Istio is an open, platform-independent service mesh that manages communications between services in a transparent way. With a distributed architecture many things can fail, slow down and become less secure. Istio provides solutions to those stresses in our plot toward this architecture style:

        • Traffic management

        • Observability

        • Policy enforcement

        • Service identity and security

     

    We will explore these benefits with Istio through some working examples on Kubernetes. The key point is this meshing solution allows your Java code to be less coupled to the inherent weaknesses of a distributed platform.

    • An Introduction to Domain Driven Design

      Attended: 172
      Thursday September, 13, 2018 06:00 PM

    Today’s enterprise applications are complex, distributed and mission critical. In this session we want to share how the concepts, tools and patterns introduced by Domain Driven Design helped us in enterprise application architecture and design. DDD is invaluable in strategic architectural decision making. DDD was instrumental for us to layout our microservices architecture. We learned to speak DDD and adopted that as our medium of communication to build our team. DDD made our communication with outside teams and integration within the enterprise easier. It made us conscious about implications of enterprise integration at strategic and implementation level.

     

    This presentation will include concepts of strategic and tactical DDD. It is also organized in such a way to encourage discussion rather than follow a strict lecturing mode.
