What is Kuberentes and should I care?

With the widespread use of containerisation, Kubernetes has become the de-facto standard for orchestrating and managing containerised applications. In this talk Salman will go through the Kubernetes architecture and talk about some of its features. The talk will end with a demo of how Kubernetes can be used to accelerate software development.
