Introducing ECS Purchase Options

Updated on 2025-01-02 GMT+08:00

Huawei Cloud provides multiple options for you to purchase ECSs.

Table 1 Purchase options of ECSs

How to Purchase

Description

Purchasing an ECS in Custom Config Mode

General operation guide for purchasing an ECS. You can flexibly set required parameters for your ECS, including the billing mode, instance specifications, image, storage, network, security group, and EIP.

Purchasing a Spot ECS

Operation guide for purchasing a spot ECS. Spot ECSs allow you to use spare ECS capacity which is available for less than the pay-per-use price.

This is a good option if you want to enjoy the same performance at a lower price.

Purchasing a Spot Block ECS

Operation guide for purchasing a spot block ECS. Spot block ECSs allow you to use spare ECS capacity which is available for less than the pay-per-use price.

This is a good option if you want to enjoy the same performance at a lower price.

Purchasing an ECS Using a Private Image

A private image contains an OS, preinstalled public applications, and user's personal applications, saving the time for configuring the ECS repeatedly.

This is a good option if you are accustomed to using certain OS and applications.

Purchasing ECSs Using Auto Launch Groups

Auto Launch Groups consists of Launch Template and Auto Launch Group.

  • A launch template stores instance creation parameters (excluding the password) so that you can use it to batch create ECS instances with the same configurations.
  • An auto launch group lets you customize configurations and rapidly create ECSs that are of different types, billed in different modes, and distributed across multiple AZs.

Purchasing an ECS in a Shared Subnet

You can create an ECS in a VPC subnet shared by another account for unified resource management, improve efficiency, and reduced O&M costs.

Purchasing the Same ECS

This function allows you to quickly purchase ECSs with the same configurations as the current ECS, which saves configuration time.
