Amazon EC2 Auto Scaling is designed to automatically launch and terminate EC2 instances based on user-defined scaling policies, scheduled actions, and health checks.
For more information, see the Amazon EC2 Auto Scaling User Guide and the Amazon EC2 Auto Scaling API Reference.

Amazon EC2 Auto Scaling configures instances launched as part of an Auto Scaling group using either a launch template or a launch configuration. We strongly recommend that you do not use launch configurations. They do not provide full functionality for Amazon EC2 Auto Scaling or Amazon EC2. For information about using launch templates, see Launch templates in the Amazon EC2 Auto Scaling User Guide.

Controls whether instances in this group are launched with detailed (true) or basic (false) monitoring.
The default value is true (enabled).
When detailed monitoring is enabled, Amazon CloudWatch generates metrics every minute and your account is charged a fee. When you disable detailed monitoring, CloudWatch generates metrics every 5 minutes. For more information, see Configure Monitoring for Auto Scaling Instances in the Amazon EC2 Auto Scaling User Guide.

When you change your maximum price by creating a new launch configuration, running instances will continue to run as long as the maximum price for those running instances is higher than the current Spot price.
Specifies whether the launch configuration is optimized for EBS I/O (true) or not (false). The optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization is not available with all instance types. Additional fees are incurred when you enable EBS optimization for an instance type that is not EBS-optimized by default. For more information, see Amazon EBS-optimized instances in the Amazon EC2 User Guide for Linux Instances.
The default value is false.
Specifies whether to assign a public IPv4 address to the group's instances. If the instance is launched into a default subnet, the default is to assign a public IPv4 address, unless you disabled the option to assign a public IPv4 address on the subnet. If the instance is launched into a nondefault subnet, the default is not to assign a public IPv4 address, unless you enabled the option to assign a public IPv4 address on the subnet.
If you specify true, each instance in the Auto Scaling group receives a unique public IPv4 address. For more information, see Launching Auto Scaling instances in a VPC in the Amazon EC2 Auto Scaling User Guide.
If you specify this property, you must specify at least one subnet for VPCZoneIdentifier when you create your group.
The tenancy of the instance, either default or dedicated. An instance with dedicated tenancy runs on isolated, single-tenant hardware and can only be launched into a VPC. To launch dedicated instances into a shared tenancy VPC (a VPC with the instance placement tenancy attribute set to default), you must set the value of this property to dedicated. For more information, see Configuring instance tenancy with Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.
If you specify PlacementTenancy, you must specify at least one subnet for VPCZoneIdentifier when you create your group.
Valid values: default | dedicated
The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.
If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.
If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.
The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

To define a block device mapping, set the device name and exactly one of the following properties: Ebs, NoDevice, or VirtualName.
Setting this value to true prevents a volume that is included in the block device mapping of the AMI from being mapped to the specified device name at launch.
If NoDevice is true for the root device, instances might fail the EC2 health check. In that case, Amazon EC2 Auto Scaling launches replacement instances.

The snapshot ID of the volume to use.
You must specify either a VolumeSize or a SnapshotId.
The volume size, in GiBs. The following are the supported volumes sizes for each volume type:

io1: 4-16,384
st1 and sc1: 125-16,384
standard: 1-1,024

For gp3 and io1 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
The following are the supported values for each volume type:
gp3: 3,000-16,000 IOPS
io1: 100-64,000 IOPS
For io1 volumes, we guarantee 64,000 IOPS only for Instances built on the Nitro System. Other instance families guarantee performance up to 32,000 IOPS.
Iops is supported when the volume type is gp3 or io1 and required only when the volume type is io1. (Not used with standard, gp2, st1, or sc1 volumes.)
Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types. If your AMI uses encrypted volumes, you can also only launch it on supported instance types.
If you are creating a volume from a snapshot, you cannot create an unencrypted volume from an encrypted snapshot. Also, you cannot specify a KMS key ID when using a launch configuration.
If you enable encryption by default, the EBS volumes that you create are always encrypted, either using the Amazon Web Services managed KMS key or a customer-managed KMS key, regardless of whether the snapshot was encrypted.
For more information, see Use Amazon Web Services KMS keys to encrypt Amazon EBS volumes in the Amazon EC2 Auto Scaling User Guide.
