Containers and Kubernetes with the concepts of application-centric packaging, process isolation through Linux containers, and immutable infrastructure are shaking up the core traditions of today's GNU/Linux operating systems. We are challenging assumptions and approaches derived from the past 40+ years of UNIX tradition. The Linux distribution as we know it, is morphing into new concept of containerized, multi-instance, multi-user applications, which can be deployed in scale-out environments. In this session, we'll assess this new OS environment and take a deep look at the consequences this new OS model has for both developers and operators.
