The following options are available when using AWS:

• machines.platform.aws.rootVolume.iops - the reserved IOPS of the root volume
• machines.platform.aws.rootVolume.size - the size (in GiB) of the root volume
• machines.platform.aws.rootVolume.type - the storage type of the root volume
• machines.platform.aws.type - the EC2 instance type
• machines.platform.aws.zones - a list of the availability zones that the installer will use when creating machines of this pool
• platform.aws.region - the AWS region that the installer will use when creating resources
• platform.aws.userTags - a map of keys and values that the installer will add as tags to all resources it creates
