Can a IaaS with "premium disks" migrate between different availability zones within the same region?
If we wanted to have HA between servers would it be best to use scale sets or a LB between avail zones(AZ) within the same region? Is there a minimum # of IaaS for a scale set?,... can we do this with two IaaS in a scale set?
I am thinking a LB cannot migrate between AZs within the same region hence would not provide HA?,... please confirm.
