Elastic Compute Service:Create an instance with Quick Purchase or Quick Launch

Last Updated:Jun 16, 2026

The Quick Launch method uses the subscription billing method by default. You can create a subscription ECS instance in minutes. This simplified process makes configuration faster and easier. This topic describes how to create an ECS instance by using Quick Launch.

Prerequisites

Default configurations

When you use Quick Launch to create an ECS instance, the system automatically configures some parameters to speed up the setup process. The following table describes the default settings.

Parameter

Default configuration

Billing method

Only subscription is supported.

Zone

The system randomly assigns a zone. You cannot change the zone.

VPC and vSwitch

The system uses a default VPC and vSwitch. For more information, see Default VPCs and vSwitches.

Security group

The system uses a default security group. You can change the security group after the instance is created. For more information, see Associate a security group with an instance.

Disk

The instance includes a 40 GiB system disk by default. No data disk is attached.

Password

A password is not set. You must reset it after you create the instance. For more information, see Reset the logon password of an instance.

Instance name

The system randomly generates an instance name.

Procedure

  1. Go to the ECS instance buy page.

  2. On the instance creation page, click the Quick Launch tab in the upper-left corner.

    Parameter

    Description

    Example

    Region and Zone

    Select a region close to your geographic location to reduce network latency. You cannot change the region and zone after you create the instance. For more information, see Regions and zones.

    China (Hangzhou)

    Instance Type

    Quick Launch supports only t5 burstable instances. To use other instance types, create an instance by using the Custom Purchase method.

    2 vCPU, 4 GiB (t5 burstable instance)

    Images

    An image contains the information required to run an instance. Quick Launch supports CentOS, Windows Server, and Ubuntu. The Quick Launch method does not support custom image or Marketplace image. To use more image options, use the Custom Purchase method.

    After you create an instance, you can change its operating system to use a different image.

    CentOS 7.9 64-bit

    Network Type

    The default network type is VPC.

    The system uses default values for the VPC, vSwitch, and security group. To specify custom settings for these resources, create an instance by using the Custom Purchase method.

    VPC

    Public Bandwidth

    You must assign a public IP address to the instance if it needs to access the internet.

    • Pay-by-bandwidth: You pay a fixed rate for a specified amount of bandwidth. The outbound bandwidth cannot exceed the specified value. This method is suitable for workloads with stable bandwidth requirements.

    • Pay-by-traffic: You are charged for the actual amount of data that you transfer. This method is suitable for workloads that have significant fluctuations in network traffic. To prevent high costs, you can specify a peak bandwidth.

    • Select Assign Public IPv4 Address.

    • Pay-by-bandwidth

    • 1 Mbps

    Quantity

    The number of instances to create.

    1

    Duration

    Select a subscription duration and specify whether to enable auto-renewal.

    Auto-renewal helps prevent service disruptions from an expired subscription and reduces the need for manual renewal.

    • 1 Month

    • Select Enable auto-renewal.

  4. In the lower-right corner of the page, click Preview.

  5. On the Confirm Order page, confirm the selected instance configuration, read the Cloud Server ECS Terms of Service | General Terms of Service, select the ECS Service Terms checkbox, and click Confirm Order.

Next steps

You cannot set logon credentials when using the Quick Launch method. After you create the instance, you must reset its password in the ECS console. For more information, see Reset the logon password of an instance.
