********** Watch this presentation on-demand! https://info.lightbend.com/iot-megaservices-high-throughput-microservices-with-akka-register.html ********** In this interactive presentation by Hugh McKee, Developer Advocate at Lightbend, we’ll share our experiences helping our clients create a system architecture that can support high throughput microservices (aka "Megaservices"). We’ll do that using IoT demo applications designed to push cloud service providers like Amazon and Google to their limits. Using sample code that you can later run on your own machine, we’ll look at: * Modeling real-life digital twins for hundreds of thousands of IoT devices in the field, looking into how these megaservices are implemented in Akka. * Visualizing Akka Actors–which represent IoT digital twins–in a “crop circle” formation that represents a complete distributed Reactive application, and watching at messages are processed across Akka Cluster nodes using cluster sharding. * Some code behind the whole set up, which is built using OSS like Akka, Java, JavaScript, and Kubernetes.
