Containers have taken an important role in existing IT configuration and deployment stacks. In the first part of this lecture we will go through the internals of what a container is made of, why they work well as a basic building block for complex applications, and cover cgroups and the different linux namespaces available as the key features they rely on.


The second part will focus on orchestrating complex distributed applications using Kubernetes, which in the last few years has built a large community around it. We will start with how to define and manage the deployment of a multi-tier application and go through how Kubernetes handles replication, restarts, log collection and other key features. We will finish briefly covering more advanced features such as ingress, pod and cluster auto scaling and monitoring.

Ricardo is a software engineer at CERN currently part of the CERN cloud team, focusing primarily on networking and container based deployments. Previously he helped develop and deploy several components of the Worldwide LHC Computing Grid, a network of ~200 collaborating sites around the world helping to analyze the Large Hadron Collider data.
Ricardo has presented his and his teams work in different international conferences - Computing for High Energy Physics (CHEP), IEEE NSS/MIC, IEEE MSST, DockerCon, Kubecon and multiple OpenStack summits.
Spyros is a computing engineer and a member of the CERN Cloud infrastructure team which provides computing resources to the High Energy Physics community. He has been contributing to open source projects like Fedora, Kubernetes and OpenStack.
