EnableFastLaunch
When you enable faster launching for a Windows AMI, images are pre-provisioned, using snapshots to launch instances up to 65% faster. To create the optimized Windows image, Amazon EC2 launches an instance and runs through Sysprep steps, rebooting as required. Then it creates a set of reserved snapshots that are used for subsequent launches. The reserved snapshots are automatically replenished as they are used, depending on your settings for launch frequency.
Note
To change these settings, you must own the AMI.
Request Parameters
The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.
- DryRun
-
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is
DryRunOperation. Otherwise, it isUnauthorizedOperation.Type: Boolean
Required: No
- ImageId
-
The ID of the image for which you’re enabling faster launching.
Type: String
Required: Yes
- LaunchTemplate
-
The launch template to use when launching Windows instances from pre-provisioned snapshots. Launch template parameters can include either the name or ID of the launch template, but not both.
Type: FastLaunchLaunchTemplateSpecificationRequest object
Required: No
- MaxParallelLaunches
-
The maximum number of instances that Amazon EC2 can launch at the same time to create pre-provisioned snapshots for Windows faster launching. Value must be
6or greater.Type: Integer
Required: No
- ResourceType
-
The type of resource to use for pre-provisioning the Windows AMI for faster launching. Supported values include:
snapshot, which is the default value.Type: String
Required: No
- SnapshotConfiguration
-
Configuration settings for creating and managing the snapshots that are used for pre-provisioning the Windows AMI for faster launching. The associated
ResourceTypemust besnapshot.Type: FastLaunchSnapshotConfigurationRequest object
Required: No

The type of resource that was defined for pre-provisioning the Windows AMI for faster launching.
Type: String
Valid Values:
snapshot - snapshotConfiguration
-
Settings to create and manage the pre-provisioned snapshots that Amazon EC2 uses for faster launches from the Windows AMI. This property is returned when the associated
resourceTypeissnapshot.Type: FastLaunchSnapshotConfigurationResponse object
