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. |

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 public cloud user.

Disk |
Includes system and data disks.

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. |

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:
- Do not use: An ECS without an EIP cannot access the Internet. However, it can still be used as a service ECS or deployed in a cluster on a private network.
- Automatically assign: An EIP with a dedicated bandwidth is automatically assigned to each ECS. You can set the bandwidth size. If you select Automatically assign, you need to specify EIP Type, Billed By, and Bandwidth.

Key Pair |
A key pair is used for ECS login authentication. 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. Without the key, you will not be able to log in to your instance.

Advanced Settings |
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.
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.
