Does / Will AKS support spreading pods across update domains?
10/26/2018
According to this article (April 2018) AKS is capable of intelligently placing pods across fault domains when running in an availability set, but it does not consider update domains yet. Will update domains be used to place pods in AKS anytime soon?
It already does this automatically when you setup your cluster. Your nodes are placed into an availability set and in that availability set they are placed into separate fault domains and update domains.
