AWS Auto Scaling Group

As a newbie to AWS concepts, I am trying to understand ASG concept.

a) Does it work per region or per Availability Zones?

b) Do I need to have an ASG for each Availability zone, or it can scale up and down the instances from different AZs on a shared region?

You can have an autoscale group work across availability zones, but not across regions.

Though it is possible to have an ASG in a single AZ, you would certainly want the ASG to be in multiple AZ's, otherwise you have no real fault tolerance in the case where an AZ has problems.
