This should be used in place of id when trying to reference the construct.

Protected Readonly physicalReturns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.
This value will resolve to one of the following:
"my-awesome-bucket")undefined, when a name should be generated by CloudFormationOptional Readonly spotThe maximum spot price configured for the autoscaling group. undefined
indicates that this group uses on-demand capacity.
Readonly stackThe network connections associated with this resource.
The IAM Role in the instance profile

The Base64-encoded user data to make available to the launched EC2 instances.

Use a CloudFormation Init configuration at instance startup
This does the following:
cfn-init and cfn-signal.cfn-init to finish
before reporting success.Optional options: ApplyCloudFormationInitOptionsApply the given removal policy to this resource
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.
The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS
account for data recovery and cleanup later (RemovalPolicy.RETAIN).
Protected generateProtected getReturns an environment-sensitive token that should be used for the
resource's "ARN" attribute (e.g. bucket.bucketArn).
Normally, this token will resolve to arnAttr, but if the resource is
referenced across environments, arnComponents will be used to synthesize
a concrete ARN with the resource's physical name. Make sure to reference
this.physicalName in arnComponents.
The CFN attribute which resolves to the ARN of the resource.
Commonly it will be called "Arn" (e.g. resource.attrArn), but sometimes
it's the CFN resource's ref.
The format of the ARN of this resource. You must
reference this.physicalName somewhere within the ARN in order for
cross-environment references to work.
Protected getReturns an environment-sensitive token that should be used for the
resource's "name" attribute (e.g. bucket.bucketName).
Normally, this token will resolve to nameAttr, but if the resource is
referenced across environments, it will be resolved to this.physicalName,
which will be a concrete name.
The CFN attribute which resolves to the resource's name.
Commonly this is the resource's ref.
Scale out or in to achieve a target request handling rate
The AutoScalingGroup must have been attached to an Application Load Balancer in order to be able to call this.
Static fromStatic isChecks if x is a construct.
Use this method instead of instanceof to properly detect Construct
instances, even when the construct library is symlinked.
Explanation: in JavaScript, multiple copies of the constructs library on
disk are seen as independent, completely different libraries. As a
consequence, the class Construct in each copy of the constructs library
is seen as a different class, and an instance of one class will not test as
instanceof the other class. npm install will not create installations
like this, but users may manually symlink construct libraries together or
use a monorepo tool: in those cases, multiple copies of the constructs
library can be accidentally installed, and instanceof will behave
unpredictably. It is safest to avoid using instanceof, and using
this type-testing method instead.
Any object
true if x is an object created from a class which extends Construct.

Construct which creates an Auto Scaling group.
By default, all EC2 instances in this group will use [[
GuInstanceRole]], which provides common permissions (e.g. the ability to download an artifact and write logs to the account's logging Kinesis stream).If additional IAM permissions are required, a custom role can be provided via the
roleprop. You may wish to instantiate [[GuInstanceRole]] yourself as a basis for this custom role, as it allows custom permissions to be passed in.All EC2 instances in this group will be automatically associated with two security groups:
GuHttpsEgressSecurityGroup]], which allows outbound traffic over HTTPS.GuWazuhAccess]], which allows instances to communicate with Wazuh (for security monitoring).If additional ingress or egress rules are required, define custom security groups and pass them in via the
additionalSecurityGroupsprop.All EC2 instances provisioned via this construct will use IMDSv2.
