This API operation is superseded by AttachTrafficSources, which can attach
multiple traffic sources types. We recommend using AttachTrafficSources to
simplify how you manage traffic sources. However, we continue to support AttachLoadBalancerTargetGroups.
You can use both the original AttachLoadBalancerTargetGroups API operation
and AttachTrafficSources on the same Auto Scaling group.
Attaches one or more target groups to the specified Auto Scaling group.
This operation is used with the following load balancer types:
Application Load Balancer - Operates at the application layer (layer 7) and supports HTTP and HTTPS.
Network Load Balancer - Operates at the transport layer (layer 4) and supports TCP, TLS, and UDP.
Gateway Load Balancer - Operates at the network layer (layer 3).
To describe the target groups for an Auto Scaling group, call the DescribeLoadBalancerTargetGroups API. To detach the target group from the Auto Scaling group, call the DetachLoadBalancerTargetGroups API.
This operation is additive and does not detach existing target groups or Classic Load Balancers from the Auto Scaling group.
For more information, see Use Elastic Load Balancing to distribute traffic across the instances in your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginAttachLoadBalancerTargetGroups and EndAttachLoadBalancerTargetGroups.
