This must be a simple one. I am a little lost here, trying to control instance placement and not really understanding how it works by reading docs.
I have an application that will have 4 Instances created for . I want them to be placed in different Availability Zones.
Here is my setup. I have 8 compute nodes, 4 Availability Zones (different racks).
AZ-1: compute1 compute2 AZ-2: compute3 compute4 AZ-3: compute5 compute6 AZ-4: compute7 compute8
Is there a recommended way/scheduler/filter to boot instances balanced across multiple Availability zones without explicitly saying which AZ to use. ?
