    Elastic Compute Service:Regions and zones

    Last Updated:Dec 18, 2025

    This topic describes the regions and zones supported by Elastic Compute Service.

    Background information

    Select a region

    When purchasing an ECS instance, select a region based on the following factors. If you select the wrong region, create an instance in the correct region and then release the original one. Alternatively, migrate the service. For instructions, see Migrate ECS instances between different accounts or within the same account.

    Factor

    Description

    Geographic location and user proximity

    • To ensure a good user experience, minimize network latency. In addition to line quality, geographic distance is a key factor in network latency.

    • Deploying resources in a region closer to your users reduces network latency and improves access speed.

    • Choose a region based on the latency requirements of your business scenario.

    Internal network communication between cloud services

    When ECS and other cloud services are in the same Region, they can communicate through a Virtual Private Cloud (VPC) network. This communication is faster than using the public network and does not incur traffic fees.

    Important

    If you purchased a cloud network service to connect cloud services, ignore this factor.

    • If you do not want cloud services to communicate with each other over the internal network, deploy the services in different regions or in the same region.

    • If your services require internal network communication, deploy them in the same Region.

    Accessing ECS instances in other countries and regions from China

    ECS instances in China regions, including China (Hong Kong) and China (Macao), may result in high latency and potential packet loss when accessing ECS instances in other countries and regions over the public network. Deploy your services in the same region to avoid these issues.

    Resource pricing

    • Resource plan prices may be lower in some regions due to different discount policies.

    • Resource prices may vary by regions. You can view the prices on the ECS product page or instance buy page. For more information, see the Instance buy page and the Pricing tab of the ECS product page.

    Product features

    New ECS features are often released as public previews in select Regions. To try these new features, create ECS instances in the specified Regions. For a record of feature releases, see Release notes for ECS features.

    Select a zone

    Important

    Select an zone when you create or purchase an Alibaba Cloud resource. You cannot change a resource's zone after the resource is created. To change the zone for an ECS instance, migrate it. For more information, see Change instance types across zones.

    Zones within the same region are interconnected over an internal network. Zones are independent of each other, which provides effective fault isolation. Incidents in one zone do not affect operations in another zone. We recommend that you appropriately distribute your services across multiple zones based on your requirements for disaster recovery and network latency.

    • If your application requires high disaster recovery capabilities, we recommend that you deploy instances in different zones within the same region.

    • If your application requires low latency, we recommend that you deploy instances within the same zone.

    For high availability, a typical disaster recovery architecture uses multi-zone primary/secondary solutions for services like ECS and File Storage NAS (NAS).

    Important

    The following tables describe all regions and zones supported by Elastic Compute Service. The regions and zones supported by each cloud service may vary. For information about the regions and zones supported by a specific cloud service, see the documentation of the cloud service.

    Query available regions

    Call the DescribeRegions operation to query the regions available for ECS.

    Use the following command-line interface (CLI) command. Replace {RegionId} with a valid region ID. 

    aliyun ecs DescribeRegions --region {RegionId}

    Query the list of resources in an availability zone

    Call the DescribeZones operation to query information about the availability zones and the resources available for purchase in a specified region.

    Use the following CLI command. Replace {RegionId} with a region ID in the preceding tables. 

    aliyun ecs DescribeZones --region {RegionId}

    Query regions where an instance type is available

    Available instance types vary by region. To view the availability of a specific instance type in each Region, go to Instance types available for each region.image

    Relationship between regions and endpoints

    An endpoint is the access domain name for an ECS service. ECS supports public endpoints and VPC endpoints. When using an SDK, the CLI, or an API to integrate ECS, you must configure the correct endpoint to connect to the service. For information about the endpoints supported by ECS, see the following topics:
