Lightweight Feature Envs w/ Spring Cloud & K8s

Automated builds and deployments are standard procedures nowadays - but the environments we deploy to are often still heavyweight and hardly fully automated.

Spawning new environments on demand can soon get pretty expensive, in terms of effort but also in terms of hard cash when using cloud services like AWS.

In this talk we are going to reflect about the different types of environment isolation and their pros and cons.

Finally, we will talk and see the concept of "Lightweight Environments" which we use in our system in order to test individual features of one or more services embedded in a complex infrastructure.

Apache FreeMarker - Why Every Developer Needs A Template Engine

Being a lazy programmer is hard work - you also need to automated those “boring copy & pasta text tasks”. I started with Groovy & Apache Velocity, automated even more boring tasks, ditched Groovy & Velocity in favour of JDK & Apache FreeMarker, wrote “freemarker-cli" and use Apache FreeMarker to implement simple web UI nowadays. Long story short - if you need to transform access logs, CSV, Excel, HTML, JSON, XML or YAML into some other textual representation (aka CSV, HTML, Markdown Confluence) or require a quick & dirty UI for a JVM-based micro service then this presentation is for you.
