    Speaker: Jonathan Johnson

    So you have some code and it is in a bounded context with a REST API. You are on your way to Microservices. Next you wrap it in a container and now it is an image that others can run. Simple. Now what? No service is an island. Your service needs to log information, needs to scale and load balance between its clones. Your service needs environment and metadata way outside its context. What about where the service will run? Who starts it? What monitors its health? What about antifragility? Updates? Networking? Oh my.

    Services live in clusters and clusters live in data centers. There are hybrid solutions that span data centers. Many concepts overlap with the features of cloud management. But don't get too flustered since, fundamentally, services are managed by clusters. There are several approaches to cluster management such as Docker Swarm, Mesos with Marathon and Kubernetes.

    Minikube with Kubernetes is an approachable technique to set up a local cluster that is easy to understand and get started. Whether you have a simple service or a Web application with a set of services, you can develop much of it on Kubernetes with Minikube. We will run some practical examples. Once you understand the mechanics of the tools, we will explore how it works, sort through the terminology and share ideas about practical uses for this technology.

    Afterward you will understand how to run your personal cluster with your Linux, OS X or Windows laptop to further enjoy unravelling the mysteries of running applications in a cluster.

    Speaker Biography

    Jonathan Johnson has been engineering and shipping commercial software for some twenty years. The software has the amazing potential to improve and even save lives. Sadly, the lousy software can miss this potential. His journey is driven by delivering helpful software to move us forward.

    His early work began with laboratory instrument software and managing its data. Jonathan was enticed by the advent of object-oriented design and Windows to develop personal banking software. Banking soon turned to the internet and enterprise applications took off. Java exploded onto the scene and since then he has inhabited that ecosystem. At 454 Life Sciences and Roche Diagnostics Jonathan returned to laboratory software and leveraged Java-based state machines and enterprise services to manage the terabytes of data flowing out of DNA sequencing instruments. 
    Today his journey continues with Thermo Fisher Scientific as a hands-on architect continuously delivering a platform that utilizes microservices. Laboratories leverage this platform for customized medicine, drug development, food safety and furthering research into challenging diseases.

    Jonathan enjoys comparing and sharing his journey with peers. He shares ways to modernize application architectures to adhere to the fundamentals of high modularity and loose coupling. A longtime resident of Connecticut, he discusses his experiences with Connecticut Java User Group, NewHaven.io and DevOps CT. You will often see Jonathan schooling and retooling on the NFJS tours.

    I'm excited about this event!

    I repeatedly tried to cancel my attendance, so someone else can attend. But the website will not cancel my confirmation. (Pressing the red X against the attendance doesn't do anything.) BobBaig

    Emails received told me that I'm registered, and from two different accounts, and I didn't registered from any account.
    norbert kremer on Jun 8, 2018 8:36 AM
    same here. I got email saying I was registered, but I had not registered. upon reviewing email, I decided I want to go, and tried to register on web site, but there are no more spaces available, so I signed up for wait list. it's not clear to me if I am actually registered, as earlier email indicates.

    Apologies to those who have received false registration message. It was an error on our part, we will fix it ASAP. You need to take no action at this time.
    mark ellison on Jun 12, 2018 10:29 AM
    yea...just tried to unregister under MY_ACCOUNT->My_Events, but the listing remains...hopefully, this will be remedied.

    I noticed it only recognizes my email address (to get password) if I write my email address in all-lower-case.

    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.
