What is Global Acceleration

Last Updated: Jun 04, 2018

Global Acceleration is a network acceleration product based on Alibaba's global backbone network. Global Acceleration enables quick network access from the nearest access point, which reduces the network impact on service quality such as latency, jitter, and packet loss, and creates a better user experience for global users of your services.

You can create and configure a Global Acceleration instance to accelerate the Internet access of an application for users worldwide. As shown in the following figure, you can create a Global Acceleration instance to accelerate the Internet access for applications deployed in an ECS instance or an SLB instance located in China North 2 (Beijing) for users in western United States. For more information on configuring a Global Acceleration instance, see Quick Start.

Currently, Global Acceleration only supports accelerating the Internet access for applications deployed in ECS instances and SLB instances of the VPC network.

Components

Global Acceleration consists of the following components:

  • Global Acceleration instances

    Before using Global Acceleration, you must buy and create a Global Acceleration instance. The Global Acceleration instance enables accelerated network access for the global users of your services.

  • Accelerated area

    An accelerated area refers to the area that requires access acceleration for your service. Select the accelerated area in which you want to create a Global Acceleration instance to optimize service access for your customers. After selecting the accelerated area, you must select a specific region where the instance is created.

    An accelerated area is a collection of Alibaba Cloud regions. Each accelerated area contains one or more regions as shown in the following table.

    Accelerated areaIncluded regions
    China Mainland

    China North 1 (Qingdao)

    China North 2 (Beijing)

    China North 3(Zhangjiakou)

    China North 5(Hohhot)

    China East 1 (Hangzhou)

    China East 2 (Shanghai)

    China South 1 (Shenzhen)

    North America

    US West 1 (Silicon Valley)

    US East 1 (Virginia)

    For example, if you want to accelerate your service access for users in North America, then select North America as the accelerated area when you create a Global Acceleration instance. A public IP is assigned to the Global Acceleration instance in the selected region for North America users to access your service.

  • Service area

    A service area refers to the area where the ECS instance or the SLB instance, hosting the backend service to be accelerated, is located.

    A service area is a collection of Alibaba Cloud regions. Each service area contains one or more regions as shown in the following table.

    Service areaIncluded regions
    China Mainland

    China North 1 (Qingdao)

    China North 2 (Beijing)

    China North 3(Zhangjiakou)

    China East 1 (Hangzhou)

    China East 2 (Shanghai)

    China South 1 (Shenzhen)

    North America

    US West 1 (Silicon Valley)

    US East 1 (Virginia)

    For example, if the website to be accelerated is deployed in an ECS instance in China North 2, then select China Mainland as the service area when you create a Global Acceleration instance.

  • Backend service

    A backend service is the service that you want to accelerate. You can bind an ECS instance or an SLB instance to a Global Acceleration instance. The backend service must be located in the region of the selected service area.

    Note: Only the ECS instances and SLB instances of the VPC network are supported.
