Region |
A region is where an AS configuration resides. |
N/A |
Name |
Specifies the name of the AS configuration to be created. |
N/A |
Configuration Template |
Select Create a new specifications template.
If this option is selected, configure parameters, such as the vCPUs, memory, image, disk, and ECS type, to create a new AS configuration. |

CPU Architecture |
Both x86 and Kunpeng CPU architectures are available:
- x86: The x86-based CPU architecture uses Complex Instruction Set Computing (CISC).
- Kunpeng: The Kunpeng-based CPU architecture uses Reduced Instruction Set Computing (RISC).
NOTE:
This parameter is displayed only when both x86-based and Kunpeng-based ECSs are available in the current region.

Specifications |
The public cloud provides various ECS types for different application scenarios.
For more information, see Elastic Cloud Server User Guide.
Configure the ECS specifications, including vCPUs, memory, image type, and disk, according to the ECS type. |
Memory-optimized ECS |
Image |
- Public image
A public image is a standard, widely used image. It contains an OS and preinstalled public applications and is available to all users. You can configure the applications or software in the public image as needed.
- Private image
A private image is an image available only to the user who created it. It contains an OS, preinstalled public applications, and the user's private applications. Using a private image to create ECSs frees you from configuring multiple ECSs repeatedly.
- Shared image
A shared image is a private image shared by another user.

Public image |
Disk |
Includes system disks and data disks.
- System Disk
Common I/O: uses Serial Advanced Technology Attachment (SATA) drives to store data.
High I/O: uses serial attached SCSI (SAS) drives to store data.
Ultra-high I/O: uses solid state disk (SSD) drives to store data.
If a full-ECS image is used, the system disk is restored using the disk backup. On the console, you can only change the volume type and size. In addition, the volume cannot be smaller than the disk backup.
- Data Disk
You can create multiple data disks for an ECS instance. In addition, you can specify a data disk image for exporting data.
If the image you selected is a full-ECS image, you can change the volume type and size and encryption attributes of the data disk restored using the disk backup. Ensure that the disk is at least as big as the disk backup. The encryption attributes can only be modified if the disk backup is in the same region as the disk.

Common I/O for System Disk |
Security Group |
Controls ECS access within or between security groups by defining access rules. ECSs added to a security group are protected by the access rules you define. |
N/A |
EIP |
An EIP is a static public IP address bound to an ECS in a VPC. Using the EIP, the ECS provides services externally.
The following options are provided:
|
Automatically assign |
Bandwidth |
You can select Dedicated or Shared.
- Dedicated: The bandwidth can be used by only one EIP.
- Shared: The bandwidth can be used by multiple EIPs.
NOTE:
- This parameter is available only when EIP is set to Automatically assign.
- If you select Dedicated, you can select Bandwidth or Traffic for Billed By.
- The shared bandwidth can be billed only by bandwidth. You can select a shared bandwidth to which the EIP is to be added.
|
Shared |
Login Mode |
An ECS can be authorized using a key pair or a password.
- Key pair
Keys are used for authenticating the users who attempt to log in to ECS instances. If you select this mode, create or import a key pair on the Key Pair page.
NOTE:
If you use an existing key, make sure that you have saved the key file locally.
- Password
The initial password of user root (for Linux) or user Administrator (for Windows) is used for authentication. You can log in to an ECS instance using a username and password combination.
|
Admin@123 |
Advanced Settings |
This parameter allows you to configure ECS Group and User Data.
You can select Do not configure or Configure now. |
N/A |
User Data |
Enables an ECS to automatically inject user data when the ECS starts for the first time. This configuration is optional. After this function is enabled, the ECS automatically injects user data during its first startup.
For details, see Elastic Cloud Server User Guide.
The following methods are available:
- As text: allows you to enter the user data in the text box below.
- As file: allows you to inject script files or other files when you create an ECS.
NOTE:
- For Linux, if you use password authentication, this function is not supported.
- If the selected image does not support user data injection, this function is not supported.
