Registers or updates a scalable target. A scalable target is a resource that Application Auto Scaling can scale out or scale in. After you have registered a scalable target, you can use this operation to update the minimum and maximum values for your scalable dimension.
After you register a scalable target, you can create and apply scaling policies using PutScalingPolicy. You can view the scaling policies for a service namespace using DescribeScalableTargets. If you are no longer using a scalable target, you can deregister it using DeregisterScalableTarget.
/// Concurrent updates caused an exception, for example, if you request an update to an
/// Application Auto Scaling resource that already has a pending update.
///
/// The service encountered an internal error.
///
/// Your account exceeded a limit. This exception is thrown when a per-account resource
/// limit is exceeded. For more information, see
Application
/// Auto Scaling Limits.

/// An exception was thrown for a validation issue. Review the available parameters for
/// the API request.
