Creates a launch configuration.

If you exceed your maximum limit of launch configurations, the call fails. To query this limit, call the DescribeAccountLimits API. For information about updating this limit, see [Quotas for Amazon EC2 Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-quotas.html) in the _Amazon EC2 Auto Scaling User Guide_.

For more information, see [Launch configurations](https://docs.aws.amazon.com/autoscaling/ec2/userguide/LaunchConfiguration.html) in the _Amazon EC2 Auto Scaling User Guide_.

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](https://docs.aws.amazon.com/autoscaling/ec2/userguide/launch-templates.html) in the _Amazon EC2 Auto Scaling User Guide_.
