I recently needed to create a custom xml file to configure the instance types available in the LAX local zone for a Citrix Virtual Apps Deployment. In AWS parlance, you are looking to “Find an Instance type using the AWS CLI” This is what the command looks like for the LAX 1a local zone:
aws ec2 describe-instance-type-offerings --location-type "availability-zone" --filters Name=location,Values=us-west-2-lax-1a --region us-west-2
If you are looking in LAX 1b:
aws ec2 describe-instance-type-offerings --location-type "availability-zone" --filters Name=location,Values=us-west-2-lax-1b --region us-west-2
