To run an instance with run_instance I have to specify a placement because otherwise I get an error that the ami isn't available.
Now, there are multiple regions (such as US East
, US West
and so on) and multiple zones (such as us-east-1a
, us-east-1b
and so on) for every region.
Do I have to pass a specific zone to AWS or is it possible to just pass a region (like us-east-1
maybe) and let Amazon chose the zone?
I'd like to keep that decision to Amazon because I don't see any difference between the zones and it would be a little bit more complex to equally distribute instances over all zones.
