# ControlPlaneScalingTier

The scaling tier for the EKS cluster provisioned control plane.

Amazon EKS Provisioned Control Plane lets you select a scaling tier to ensure high and
predictable control plane performance for demanding workloads such as AI training/inference,
high-performance computing, or large-scale data processing.

- `TIER_8XL`: [ControlPlaneScalingTier](/cdk/api/v2/docs/aws-cdk-lib.aws_eks_v2.ControlPlaneScalingTier.html) (static) — 8x extra-large provisioned control plane tier.

- `TIER_XL`: [ControlPlaneScalingTier](/cdk/api/v2/docs/aws-cdk-lib.aws_eks_v2.ControlPlaneScalingTier.html) (static) — Extra-large provisioned control plane tier.

- `value`: string — The string value of the scaling tier as expected by the EKS API.

## Methods
