DESCRIPTION:So you're running Kubernetes. You know it runs containers on lo
 ts of machines. Bin packing 4TW! But: Those pesky\, noisy neighbors can be
  a real drag. That's where Kubernetes QoS comes in! Or does it? Meet the r
 eal magician behind the scenes: Linux cgroups\, which enforce QoS guarante
 es based on your k8s configurations.\n\nContainers are not native to the k
 ernel\; they emerge from low-level kernel concepts like cgroups\, which ar
 e the backbone of Linux resource management. As such\, they are used throu
 ghout the whole operating system\, from the init system to each of your wo
 rkloads. A deeper understanding of them will allow you to create harmony w
 ithin your Kubernetes nodes\, making sure that everything works well toget
 her and nothing steps on each other's toes.\n\nBy the end of this talk\, y
 ou will understand:\n\n* what cgroups are\,\n* the role of the different c
 omponents in cgroup management\,\n* kubelet's QoS/cgroup configuration\,\n
 * and best practices for aligning cgroups to avoid potential issues.
