This method works, but is deprecated. Use BatchGetDeploymentTargets instead.

Returns an array of one or more instances associated with a deployment. This method works with EC2/On-premises and Lambda compute platforms. The newer BatchGetDeploymentTargets works with all compute platforms. The maximum number of instances that can be returned is 25.


This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.
