Containers offer 2 central promises: software as encapsulated and reproducible units. A key corollary of those promises is the ability to schedule and manage containers automatically. This session aims to give attendees a solid understanding of leveraging or building container orchestration using feedback signals. We’ll apply engineering control theory to key container management scenarios. This will cover basic principles of observing systems, controller design, and PID controllers. In particular, we’ll dive into container scaling controllers, using both first principles and proven designs from Kubernetes and Mesos.
