# Select Your Cluster Tier

This document describes how to select your cluster tier on TiDB Cloud.

## Cluster Tier overview

When creating a cluster, you need to select a cluster tier, which determines the throughput and performance of your cluster. Different cluster tiers provide different TiDB and TiKV node instance types. Different tiers are provided for AWS and GCP.

> **Note:**
>
> You cannot change the selected tier after your cluster is created.

## AWS Tiers
