I need information about availability zones in nova. I tried googling but
cant find enough information. My questions are ,
1. Why is it that we have two concepts of aggregates and AZs ? Is one not
enough ? Like exposing aggregates and creating flavors with extra specs to
match ? Why do we need AZs also ?
2. Why is it that one node should only be a part of one AZ but not two ?
whereas in the case of aggregates, it can overlap ?
3. Also why cant we expose only aggregates like AZs but block the compute
member list to the users ? Doing this way will serve the purpose of AZ as
well ? Why we dont want to expose aggregates as AZs ?
