Purchasing an ECS in Quick Config Mode

Scenarios

Elastic Cloud Server (ECS) is a cloud server that provides scalable, on-demand resources, including vCPUs, memory, OS, and Elastic Volume Service (EVS) disks. After purchasing an ECS, you can use it like using your local computer or physical server.

The quick config mode provides basic, cost-effective, and high-performance instance specifications for you to choose from. You can specify the billing mode, region, image, public network access, and purchase details to quickly purchase an ECS.

The following describes how to purchase an ECS in quick config mode on the management console. To learn how to purchase an ECS in custom config mode, see Purchasing an ECS in Custom Config Mode.

Constraints

Only yearly/monthly and pay-per-use billing modes are supported.
Only randomly allocated AZs are supported.
You can only choose from the recommended instance specifications
Only public images are supported.

Prerequisites

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.

Procedure

Click Buy ECS on the ECS console.

Set Basic Configuration.

Set Billing Mode.

You can select an appropriate billing mode based on the required duration and resource inventory to help you save costs.

**Table 1** Billing modes
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 from it.	Yearly/Monthly Billing
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 billing mode is ideal for scenarios where resource demands fluctuate and you want more flexibility on resource usage.	Pay-per-Use Billing

Set 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.
- ECSs in different regions cannot communicate with each other over an intranet.
- Once ECSs are purchased, the region cannot be changed.

Set Instance.

The quick config mode provides basic, cost-effective, and high-performance instance specifications for you to choose from. Select appropriate instance specifications based on service requirements.

If the recommended specifications cannot meet your requirements, you can switch to the Custom Config tab. For details, see Purchasing an ECS in Custom Config Mode.

Cost-effective	High network bandwidth and PPS, suitable for medium- and light-load enterprise applications that require high computing and network performance	S7: s7.small.1, s7.large.2, s7.xlarge.2, and s7.2xlarge.2
High-performance	Higher performance, security, and stability, suitable for medium- and heavy-load enterprise applications that require high computing and network performance	C7: c7.large.2, c7.xlarge.2, c7.2xlarge.2, and c7.3xlarge.2

Set OS.
1. Select an image for the ECS.
  Only public images are provided in quick config mode. You can select an image based on service requirements.
  
  For more details, see Public Image Overview.
  
  Figure 3 OS
2. (Optional) Set Host protection (HSS).
  When you select certain public images, Host Security Service (HSS) is enabled by default. HSS Basic Edition provides one-month free trial and automatically installs the HSS agent. HSS Basic Edition provides functions such as weak password and vulnerability detection.
  
  HSS is designed to improve the overall security for ECSs. It helps you eliminate risks, defend against intrusions and web page tampering, provide advanced defense, and manage security operations.
  
  After the one-month free trial period expires, the HSS basic edition quotas will be automatically released, and HSS will not protect your servers.
  
  If you want to continue using HSS or upgrade HSS security capabilities, you need to purchase HSS. For details, see What Should I Do When the Free Trial of HSS Basic Edition Expires?
  
  After ECSs are purchased, you can switch between different HSS editions on the HSS console. For details about differences among different editions, see Specifications of Different Editions.
Set Public Network Access.
1. You can select Public Network Access to buy and bind an EIP to the ECS.
  If you do not select it, no EIPs will be assigned.
  
  If the default EIP route is sold out, Public Network Access cannot be selected.
2. (Optional) Set Billed By.
  This parameter is displayed only when Public Network Access is selected. Each bandwidth can be used by only one EIP.
  - Bandwidth: Dedicated bandwidth will be billed by size.
  - Traffic: Dedicated bandwidth will be billed by traffic you have actually used.
3. (Optional) Set Bandwidth Size.
  This parameter is displayed only when Public Network Access is selected. Select the bandwidth based on service requirements. The unit is Mbit/s.

Set Other.

Other settings use the system defaults. If you need to customize the settings, switch to the Custom Config tab.

For details, see Purchasing an ECS in Custom Config Mode.

**Table 3** Other settings
Parameter	Example	Description	Reference
AZ	Random	AZs are randomly allocated by default.	Region and AZ
