Presenter Bios 3 Abstract ​Kubernetes allows using topology labels to affect the scheduler’s placement of pods. This is used to spread pods across availability zones, while still respecting resource vSphere, the hypervisor platform also supports an underlying tier of high availability and automated placement options, for both control plane and worker nodes. 2 levels of scheduling and resource management pull pods off the queue, evaluates the pod’s requirements, and assigns it to a worker node. Placement Decision Stages: 1. Filter out impossible worker nodes a. Filters are called predicates - extensible
