Programming languages
Everything-as-code. A polyglot adventure.
As modern, agile architects and developers we need to master several different languages and technologies all at once to build state-of-the-art solutions and yet be 100% productive. We define our development environments using Gradle. We implement our software in Java, Kotlin or another JVM based language. We use Groovy or Scala to test our code at different layers. We construct the build pipelines for our software using a Groovy DSL or JSON. We use YAML and Python to describe the infrastructure and the deployment for our applications. We document our architectures using AsciiDoc and JRuby. Welcome to Babel!
Making the right choices in the multitude of available languages and technologies is not easy. Randomly combining every hip technology out there will surely lead into chaos. What we need is a customized, streamlined tool chain and technology stack that fits the project, your team and the customer’s ecosystem all at once. This code intense, polyglot session is an opinionated journey into the modern era of software industrialization.
Cloud, Containers & Infrastructure
A Hitchhiker’s Guide to the Cloud Native Stack
Cloud native applications are popular these days. They promise superior reliability and almost arbitrary scalability. They follow three key principles: they are built and composed as microservices. They are packaged and distributed in containers. The containers are executed dynamically in the cloud. But which technology is best to build this kind of application? This talk will be your guidebook.
In this hands-on session, we will briefly introduce the core concepts and some key technologies of the cloud native stack and then show how to build, package, compose and orchestrate a cloud native microservice application on top of a cluster operating system such as Kubernetes. To make this session even more entertaining we will be using off-the-shelf MIDI controllers to visualize the concepts and to remote control a Kubernetes cluster.
