This topic describes how to use a custom image to create one or more simple application servers that have the same configurations as or higher configurations than the custom image.
Prerequisites
A custom image is created. For more information, see Create a custom image.
Usage notes
Before you use a custom image to create simple application servers, take note of the following items:
The custom image can be used to create simple application servers only within the same region.
If you use a custom image to create simple application servers, the system disk size specified for the simple application servers cannot be smaller than the size of system disk data contained in the custom image. If the custom image contains data of a data disk, the data disk size specified for the simple application servers cannot be smaller than the size of data disk data contained in the custom image.
Before simple application servers are created based on a custom image, do not perform the following operations. Otherwise, the servers fail to be created.
Delete the custom image.
Delete the snapshot based on which the custom image was created.
Reset the operating system or replace the image of the simple application server from which the custom image is derived.
Release the simple application server from which the custom image is derived.
After a custom image is released or deleted, the simple application servers that are created based on the custom image cannot be reset.
Procedure
You can use one of the following methods to create simple application servers:
Method 1: Select a custom image on the Image page to create simple application servers
- Log on to the Simple Application Server console.
In the left-side navigation pane, click Image.
In the Actions column of the desired custom image, choose
> Create Simple Application Server. On the server buy page, configure parameters to create simple application servers.
The Region and Image parameters are configured by default based on the configurations of the custom image. You need to only configure other parameters based on your business requirements. The following table describes the parameters.
Parameter
Description
Instance Plan
The system selects a plan by default based on the size of system disk data contained in the custom image. You can select a plan that provides higher configurations than the default plan based on your business requirements. You are charged additional fees for outbound data transfer over the Internet beyond the plan. For more information, see Overview.
Data Disk
Optional. To have more storage space on the simple application server, you can create a data disk of the specified size and attach the data disk to the server.
NoteIf the custom image contains the data of a data disk, the default value of Data Disk is greater than or equal to the size of data disk data contained in the custom image.
Subscription Time
Select a subscription duration for the simple application server. You can select Auto-renewal based on your business requirements. If you select Auto-renewal, the simple application server is automatically renewed.
Quantity
The number of simple application servers that you want to create. The default value is 1. You can create up to 20 simple application servers.

Method 2: Select a custom image on the server buy page to create simple application servers
- Log on to the Simple Application Server console.
In the left-side navigation pane, click Servers.
Click Create Server.
On the server buy page, configure parameters to create simple application servers.
The following table describes the parameters.
Parameter
Description
Region
The region where the custom image resides.
ImportantSimple application servers deployed in regions outside the Chinese mainland such as the China (Hong Kong) and Singapore regions use international bandwidth. High network latency may occur when you access these servers from regions in the Chinese mainland. For more information, see Regions and network connectivity.
Image
Click the Custom Images tab and select a custom image from the drop-down list.
Instance Plan
The system selects a plan by default based on the size of system disk data contained in the custom image. You can select a plan that provides higher configurations than the default plan based on your business requirements. You are charged additional fees for outbound data transfer over the Internet beyond the plan. For more information, see Overview.
Data Disk
Optional. To have more storage space on the simple application server, you can create a data disk of the specified size and attach the data disk to the server.
NoteIf the custom image contains the data of a data disk, the default value of Data Disk is greater than or equal to the size of data disk data contained in the custom image.
Subscription Time
Select a subscription duration for the simple application server. You can select Auto-renewal based on your business requirements. If you select Auto-renewal, the simple application server is automatically renewed.
Quantity
The number of simple application servers that you want to create. The default value is 1. You can create up to 20 simple application servers.
