Together, Thomas Fricke, CTO of Endocode, and Jannis Rake-Revelant, Lead IT Operations, Infrastructure and Security, immmr GmbH, will show which steps need to be performed to convert a VM-based micro-service architecture to a container-based approach on the AWS cloud using CoreOS, Docker and Kubernetes.

Following an iterative proof-of-concept approach, separating persistent and stateless applications and run everything in small units orchestrated by Kubernetes we succeeded designing pods which can be rolled out easily. We could create descriptions of environments very rapidly, creating full complex systems with a single command. Examples of Java, Python and Ruby applications are shown.

The presentation will focus on: VM-based vs container-based micro services and their orchestration Preparing a customer facing service to run on Kubernetes on AWS Orchestration of a container cluster infrastructure Lessons learned An CLD (continuous live deployment) chain has been implemented to roll out new versions with minimal effort. Using the latest feature of systemd on Linux on CoreOS, we could move the configuration management into the kubernetes domain.
