You can have one or more target tracking scaling policies, one or more step scaling policies, or both. However, there is a chance that multiple policies could conflict, instructing the scalable target to scale out or in at the same time. Application Auto Scaling gives precedence to the policy that provides the largest capacity for both scale out and scale in. For example, if one policy increases capacity by 3, another policy increases capacity by 200 percent, and the current capacity is 10, Application Auto Scaling uses the policy with the highest calculated capacity (200% of 10 = 20) and scales out to 30. </p> <p>We recommend caution, however, when using target tracking scaling policies with step scaling policies because conflicts between these policies can cause undesirable behavior. For example, if the step scaling policy initiates a scale-in activity before the target tracking policy is ready to scale in, the scale-in activity will not be blocked. After the scale-in activity completes, the target tracking policy could instruct the scalable target to scale out again. </p> <p>For more information, see <a href=\"https://docs.aws.amazon.com/autoscaling/application/userguide/application-auto-scaling-target-tracking.html\">Target tracking scaling policies</a>, <a href=\"https://docs.aws.amazon.com/autoscaling/application/userguide/application-auto-scaling-step-scaling-policies.html\">Step scaling policies</a>, and <a href=\"https://docs.aws.amazon.com/autoscaling/application/userguide/aas-create-predictive-scaling-policy.html\">Predictive scaling policies</a> in the <i>Application Auto Scaling User Guide</i>.</p> <note> <p>If a scalable target is deregistered, the scalable target is no longer available to use scaling policies.
