 ** scaleInAfter **   <a name="ECS-Type-InfrastructureOptimization-scaleInAfter"></a>
This parameter defines the number of seconds Amazon ECS Managed Instances waits before optimizing EC2 instances that have become idle or underutilized. A longer delay increases the likelihood of placing new tasks on idle or underutilized instances instances, reducing startup time. A shorter delay helps reduce infrastructure costs by optimizing idle or underutilized instances,instances more quickly.  
Valid values are:  
+  `null` - Uses the default optimization behavior.
+  `-1` - Disables automatic infrastructure optimization.
+ A value between `0` and `3600` (inclusive) - Specifies the number of seconds to wait before optimizing instances.
Type: Integer  
Required: No
