How to change cloud computer specifications-Elastic Desktop Service-阿里云帮助中心

A cloud computer's specifications determine its performance level. These specifications define its computing resources, such as vCPU, memory, and video memory. You can upgrade or downgrade the specifications of a cloud computer to match your workload requirements. This topic describes how to resize a cloud computer.

Background

Resizing a cloud computer only affects its computing resources. This operation does not impact its storage resources or user data. Because the prices of the original and new specifications may differ, resizing can result in additional charges or a refund.

The limitations for different types of resize operations are as follows:

Billing method	Resize type	Limitations
All	All	Only cloud desktops of the same specification type support mutual configuration changes，that is, office-type specifications and graphics-type specifications cannot be changed between each other。 Only supports changing from one cloud desktop specification to another cloud desktop specification，you cannot individually modify configurations within a cloud desktop specification。 For the same cloud desktop，the interval between two configuration change operations must not be less than5minutes。
Monthly subscription (unlimited hours)	Upgrade	You must pay the price difference for the remainder of the current billing cycle. If you have renewed your subscription or performed a downgrade within the current billing cycle, you cannot upgrade the cloud computer until the next billing cycle begins. To convert a monthly subscription (unlimited hours) to one with a compute package, see Convert Billing Plan for Monthly Hour Package.
Monthly subscription (unlimited hours)	Downgrade	You can downgrade the specifications of a cloud computer a maximum of three times per month. Once this limit is reached, you cannot perform another downgrade until the quota is automatically reset on the first day of the next month. The refund is calculated using the following formula: `Refund Amount = Remaining Duration × (Price Difference between Old and New Specifications / Total Duration)`. The actual refund amount is shown on the user interface. Refunds are issued to the original payment method. Used coupons are not refunded. Note In this formula, Remaining Duration is the active subscription time left before the downgrade, and Price Difference is the cost difference between the original and new specifications.
Monthly subscription with compute package	All	Resizing this type of cloud computer involves unsubscribing from the current one and purchasing a new one. This action results in a refund for the old subscription and a new pending payment for the new one. To convert a subscription with a compute package to one with unlimited hours, see Convert Monthly Hour-based Billing Plan. Important The unsubscribed cloud computer will be released. Before you proceed, make sure you have backed up all important data to a secure location.

Prerequisites

The cloud computer must be in the Stopped status. For instructions, see Start, Stop, Restart, or Release Cloud Computers.
Before you resize a cloud computer, ensure that it has no pending orders. Otherwise, the operation may fail. If there are pending orders, in the top navigation bar of the console, click Price. In the left-side navigation pane of the Expenses and Costs page, click Orders > My Orders. Then, pay for or cancel the pending orders.

- For a pay-as-you-go cloud computer, select the target specifications and click Change.
- For a monthly subscription (unlimited hours) cloud computer, select the target specifications on the Upgrade Configurations or Downgrade tab and click Change.
- For a monthly subscription cloud computer with a compute package, select the target specifications, a compute package, and a subscription duration, and then click OK.
