Will it blend?

Comparison of oVirt, OpenStack and Kubernetes schedulers

This talk should explain the internal mechanisms and differences between three schedulers that are currently used to plan workload placements in today’s datacenters and clusters.

The scheduling part of cluster management is commonly perceived to be complicated and close to dark magic. My goal is to describe the really simple concepts all three schedulers are based upon. I will then focus on the significant differences and strong and weak points of each of them in hope that I will uncover features worth of sharing between schedulers.

This talks should shed some light on how cloud and cluster scheduling works and facilitate the idea exchange in the scheduling area; both in the developer community and between developers and users.
