# UES Pricing

UES product includes two charging models:

1\. Based on configuration: charges are applied based on three dimensions: CPU, memory, and storage;

2\. Based on nodes: charges apply across nodes on the basis of node configuration;

Only some existing instances use the node-based billing model, and all new instances adopt the configuration-based billing model.

> Note: Prices in this document take the E availability zone in North China 1 as an example.
