This topic describes how you are billed for ECS images and provides examples on how to calculate image fees.
|Public image||Public images are provided by Alibaba Cloud. The following public images are offered at different prices:|
Custom images are created from instances or snapshots or imported from your computer. Billing for custom images consists of two parts:
Shared images are shared with you by other Alibaba Cloud accounts. If you use a shared image that is derived from a paid image, you are charged an image fee for the shared image.
For example, if an Alibaba Cloud account shares with you a paid image and you use that image to create an instance, you are charged an image fee for the shared image.
|Alibaba Cloud Marketplace image||Alibaba Cloud Marketplace images are provided by independent software vendors (ISVs). The prices are displayed on the product pages of Alibaba Cloud Marketplace images.|
|Community image||Community images are free of charge.|
|Billing method||Billing rule|
|Subscription: You must pay for an image before you can use it.|
|Pay-as-you-go: This billing method allows you to use resources and pay for them later. Fees are automatically deducted from the balance of your Alibaba Cloud account.|
|Billing method||Billing item||Fee (USD)|
|Subscription||Price = Unit price of the image × Subscription duration = 43.00 × 1 = 43.00|
|Pay-as-you-go||Price = Unit price of the image × Billing duration = 0.063 × (24 × 30) = 45.36|
