Purchasing an ECS in Custom Config Mode
Scenarios
Elastic Cloud Server (ECS) is a cloud server that provides scalable, on-demand computing resources, including vCPUs, memory, OS, and Elastic Volume Service (EVS) disks. After creating an ECS, you can use it like using your local computer or physical server.
You can create an ECS by specifying its vCPUs, memory, OS, specifications, and login mode.
This section describes how to purchase an ECS on the management console.
Procedure
Step |
Description |
---|---|
|
|
Log in to the ECS console and open the page for purchasing ECSs. |
|
Specify parameters based on your service requirements. |
|
Confirm the configuration details and complete the purchase. |
Preparations
- Sign up for a HUAWEI ID and complete real-name authentication.
Before purchasing an ECS, sign up for a HUAWEI ID and enable Huawei Cloud services and complete real-name authentication first.
If you have enabled Huawei Cloud services and completed real-name authentication, skip this step.
- Top up your account.
Ensure that your account has sufficient balance. If not, top up your account.
- Plan network resources, such as VPCs and subnets.
When you are purchasing an ECS, the system creates a default VPC (vpc-default) and subnet (subnet-default).
If you do not want to use the default VPC and subnet, you can create a VPC and subnet in the corresponding region in advance. For details, see VPC and Subnet Planning.
- Create a security group and add rules to it.
When you are purchasing an ECS, the system creates default security groups (default, Sys-WebServer, and Sys-FullAccess). For more information about security groups and rules, see Default Security Groups and Rules.
If the default security groups and rules cannot meet your service requirements, you can modify them. For details, see Configuring Security Group Rules.
- Create a key pair.
To log in to the ECS using a key pair, create one in advance. For details, see (Recommended) Creating a Key Pair on the Management Console.
- Create dedicated physical resources.
To make your ECSs run on isolated physical hardware, apply for a Dedicated Computing Cluster (DCC) before creating the ECS.
For details, see Applying for a DCC.
- Register an edge site.
To create ECSs for CloudPond sites, register an edge site in advance.
For details, see Registering an Edge Site.
Step 1: Access the Page for Purchasing ECSs
Log in to the management console and access the ECS console.
Basic Configuration: Billing Mode, Region, and AZ
- Select a billing mode.
You can select an appropriate billing mode based on the required duration and resource inventory to help you save costs.
Table 1 Select a billing mode Option
Description
Scenarios and Constraints
Reference
Yearly/Monthly
Yearly/Monthly is a prepaid billing mode in which you pay for ECSs before using them.
Yearly/monthly ECSs are billed by the purchased duration specified in the order.
This cost-effective mode is ideal when the duration of ECS usage is predictable. This billing mode is recommended for long-term users.
A yearly/monthly ECS cannot be deleted. If such an ECS is not required anymore, unsubscribe it.
Pay-per-use
Pay-per-use is a postpaid billing mode. You pay as you go and just pay for what you use.
Pay-per-use ECSs are billed by the second and settled by the hour.
This mode is ideal when you want more flexibility and control on ECS usage.
Spot pricing
Spot pricing is a postpaid billing mode. You pay as you go and just pay for what you use. In Spot pricing billing mode, your purchased ECS is billed at a lower price than that of a pay-per-use ECS with the same specifications.
In Spot pricing billing mode, you can select Spot or Spot block for the Spot Type. Spot ECSs and Spot block ECSs are billed by the second and settled by the hour.
Spot pricing is a good option if you want to enjoy the same performance at a lower price.
In spot pricing billing mode, your purchased ECSs are not suitable for long-term workloads or workloads that require high stability.
- (Optional) Set Reserved Instance.
This parameter is displayed only when Billing Mode is set to Pay-per-use and you have applied for the open beta test (OBT) of reserved instances. If you want to associate reserved instances (RIs) with your pay-per-use ECSs, select Associate RI and select an RI.
Figure 1 Reserved instance - (Optional) Set Spot Type.
This parameter is displayed only when Billing Mode is set to Spot pricing. You can select Spot or Spot block for Spot Type.
Figure 2 Spot type- Spot: The price of spot ECSs fluctuates with the market. For details, see Purchasing a Spot ECS.
- Spot block: The price of spot block ECSs depends on the predefined duration. For details, see Purchasing a Spot Block ECS.
- Select a region.
A region refers to a physical data center area where ECSs reside. For lower network latency and faster resource access, select the region nearest to your services.
NOTE:
- ECSs in different regions cannot communicate with each other over an intranet.
- Once ECSs are purchased, the region cannot be changed.
- When you purchase ECSs for a CloudPond edge site, the default region is the region where the edge site is located and cannot be changed.
- Select an AZ.
An AZ is a physical location that uses independent power supply and networks. AZs in the same region can communicate with each other over an intranet.
Table 2 Selecting an AZ Option
Description
Scenarios and Constraints
Reference
Random
The available ECS types and flavors vary depending on AZs.
The system uses hash algorithms to allocate an AZ based on your universally unique identifier (UUID) and the ECS flavor you have selected.
To view all ECS types and flavors supported by the cloud platform, select Random for AZ.
AZN
AZs supported in the selected region. N indicates the sequence number of an AZ.
If you want to create an ECS in a specified AZ, select that AZ.
- For high availability (HA), create ECSs in different AZs.
- For low network latency, create ECSs in the same AZ.
Edge AZ
Edge AZs are deployed in on-premises data centers and are dedicated to CloudPond users.
If you are purchasing ECSs for a CloudPond edge site, an edge AZ is selected by default and it cannot be changed.
What Are the Relationships Between Edge Sites, Regions, and AZs?
Instance: Specifications, Maximum Price (for Spot ECSs), and Predefined Duration (for Spot Block ECSs)
- Choose an instance selection mode.
Table 3 Instance parameters Option
Description
Scenarios and Constraints
Reference
By Type
You can select ECS specifications based on different properties.
- CPU architecture: x86 or Kunpeng are available.
- Search filters: Filter by vCPU, memory, or keyword.
- Specifications: Select by instance family and generation.
This mode is suitable for users who are familiar with the CPU architecture, vCPUs, memory, and instance family and generation of ECSs and want to select specific specifications.

- Use existing network interface: This parameter is only displayed when the selected VPC has available network interfaces. You can select an existing network interface from the drop-down list as the primary network interface.
- (Optional) Set how an IPv6 address will be assigned. IPv6 not required is selected by default.
This parameter is displayed only when the IPv6 column of the selected ECS flavor is Yes and IPv6 is enabled for the subnet.
- IPv6 not required: No IPv6 address is allocated to the NIC.
- Automatically-assigned IPv6 address: The system automatically assigns a private IPv6 address to the NIC.
If Automatically-assigned IPv6 address is selected, the system assigns IPv6 addresses. In a VPC, ECSs use IPv6 addresses to access the dual-stack intranet.
To enable an ECS to access the Internet, you need to assign a EIP shared bandwidth, and add the ECS's IPv6 address to the shared bandwidth.
For details, see Adding EIPs to a Shared Bandwidth.
NOTE:
- For details about how to enable IPv6 for a subnet, see IPv6 Network.
- After creating an ECS, check whether the ECS has obtained an IPv6 address. If not, enable IPv6 so that the ECS dynamically obtains an IPv6 address. For details, see Dynamically Assigning IPv6 Addresses.
- (Optional) Click Add Extension NIC.
A NIC that can be separately added is an extension NIC. If you need to attach multiple NICs to an ECS, you can add multiple extension NICs and specify their IP addresses.
Extension NICs cannot communicate with external networks before you configure policy-based routes for them. For details, see Configuring Policy-based Routes for an ECS with Multiple NICs.
NOTE:

The name of a Windows ECS can contain a maximum of 15 characters and must be unique, or some Windows applications may be unavailable.
The naming rules of hostnames comply with RFC 952 and RFC 1123.
When you set the ECS name and hostname, you are advised to use letters (a-z), digits (0-9), and hyphens (-) to prevent unknown issues. In the ECS:
- Underscores (_) will be converted to hyphens (-).
- A combination of a hyphen and underscore (-_) will be converted to a hyphen (-).
- Periods (.), hyphens (-), underscores (_), and Chinese characters at the beginning of the name will be ignored.
- If periods (.) and Chinese characters are not at the beginning, they and the content following them will be ignored.
- When you purchase multiple ECSs in batches, the system automatically appends numbers to the end of each ECS name. Custom naming is supported.
- Automatic naming: The system automatically appends four-digit numbers to the end of each instance name, moving up in increments of 1. For example, if you enter ecs, the first instance will be named as ecs-0001, the second as ecs-0002, and so on.
- Customizable naming: You can create a custom naming rule using the format, "name_prefix[begin_number,bits]name_suffix", where "begin_number" is a value from 0 to 9999, and "bits" from 1 to 4. For example, if you created a custom naming rule ecs[66,3]abc and created two ECSs, the system automatically names the instances ecs066abc and ecs067abc.
- Allow duplicate name: allows ECS names to be duplicate. If you select Allow duplicate name and create multiple ECSs in a batch, the created ECSs will have the same name.
- Set Login Mode.

If your organization has created a tag policy for ECS, you need to add tags for ECS based on the tag policy. If a tag does not comply with the tag rules, the creation may fail. Contact the organization administrator to learn details about the tag policy.
After creating the ECS, you can view the tags on the pages providing details about the ECS, EIP, and EVS disks.
Advanced Settings: Cloud Eye, ECS Group, ECS Description, User Data, Agency, and CPU Options
- Set Detailed monitoring.
If you select certain public images, it is a good practice to use the host monitoring function. Host monitoring collects ECS OS metrics, such as CPU usage, memory usage, and network status, so that you can use these metrics to monitor resource utilization or locate a fault.
After you enable detailed monitoring, an agent will be installed on the ECS to provide fine-grained monitoring of ECS metrics every minute, such as vCPUs, memory, network, disk, and process.
- (Optional) Set ECS group.
An ECS group applies the anti-affinity policy to the ECSs in it so that the ECSs are automatically allocated to different hosts. For instructions about how to create an ECS group, see section Managing ECS Groups.
NOTE:
An existing ECS attached with a local disk cannot be added to an ECS group. To use ECS group functions, select an ECS group when creating an ECS.
- Add an ECS description.
- Set User Data.
You can inject user data, for example, inject the OS initialization script, to ECSs during ECS creation. During the initial start of the ECS, the data will be automatically injected.
- As text: allows you to enter the user data in the text box.
- As file: enables the text to automatically inject a script file or other files into a specified directory on an ECS when you create the ECS.
For details, see Injecting User Data.
- Set Agency.
When your ECS resources need to be shared with other accounts, or your ECS is delegated to professional personnel or team for management, the tenant administrator creates an agency in IAM and grants the ECS management permissions to the personnel or team. The delegated account can log in to the cloud system and switch to your account to manage resources. You do not need to share security credentials (such as passwords) with other accounts, ensuring the security of your account.
If you have created an agency in IAM, select the agency from the drop-down list. For more information about agencies, see Account Delegation.
- Set CPU Options.
- To configure hyper-threading for an ECS, select Specify CPU options.
For details about hyper-threading, see Enabling or Disabling Hyper-Threading.
- Set Threads per Core.
This parameter is displayed when Specify CPU options is selected. You can select a parameter value from the drop-down list.
- 1: one thread per core, which means hyper-threading is disabled.
- 2 (default value): two threads per core, which means hyper-threading is enabled.
- To configure hyper-threading for an ECS, select Specify CPU options.
Purchase Details: Required Duration, Auto-renew, Quantity, and Enterprise Project
- (Optional) Select the required duration for ECSs.
You can select how long the ECSs will be used only when Billing Mode is set to Yearly/Monthly. The duration can be from 1 month to 1 year.
- (Optional) Set Auto-renew.
This parameter is displayed only when Billing Mode is set to Yearly/Monthly.
You can select Auto-renew to automatically renew yearly/monthly resources when they expire.- Monthly: Your subscription will be automatically renewed each month.
- Yearly: Your subscription will be automatically renewed each year.
For details about auto-renewal, see Auto-Renewal Rules.
- (Optional) Determine whether to select Set scheduled deletion time for Required Duration.
This parameter is displayed only when Billing Mode is set to Pay-per-use or Spot pricing. If you select Set scheduled deletion time and set a time, the ECS will be automatically deleted when the time is reached.
NOTICE:
After you set a scheduled deletion time, the system automatically deletes the ECS at the specified time. Back up data in advance.
The scheduled deletion time must be at least 1 hour from the current time but not more than 3 years from now. You can change the scheduled deletion time before the instance is deleted.
The system executes the scheduled deletion task every 5 minutes and stops the billing after the ECS is deleted.
- Set the quantity of ECSs to be created.
You can set how many ECSs to be created in a batch. ECSs created in a batch have the same configurations.
The remaining number of ECSs you are allowed to create is displayed. To ensure effective resource usage, an upper limit is set on the ECSs to be created. If the number of ECSs you need exceeds the upper limit, increase quota.
NOTE:
You can set the following at the bottom of the purchase page:
- When Billing Mode is set to Yearly/Monthly, you can set quantity and required duration.
- When Billing Mode is set to Pay-per-use or Spot pricing, you can set quantity.
After the setting is complete, you can hover over the price to view billing items. If you have any question about the price, click Pricing details.
Step 3: Confirm the Configuration and Purchase an ECS
- In the Configuration Summary panel on the right side, confirm the ECS details.
Mandatory fields that are not configured are displayed in red. You need to set them in the parameter configuration area.
- (Optional) Click Save as Launch Template.
Perform this step only when you need to create an ECS using a launch template. For details, see Purchasing ECSs Using Auto Launch Groups.
The configuration cannot be saved as a launch template if the billing mode is yearly/monthly or spot block, host security is enabled, or the login mode is password.
- Read and select the agreement, and click Submit.
After the ECS is created, it will be started by default.
