Global Acceleration (GA) is a global network acceleration service that features high availability and high performance. This topic describes how to create and manage a GA instance.

Create a GA instance

Before you use GA, you must create a GA instance.

  1. Log on to the Global Accelerator console.
  2. On the Instances page, click Create Instance.
  3. On the buy page, set the following parameters of the instance, click Buy Now, and then complete the payment.
    Parameter Description
    Type Select a type of GA instance.
    • Basic: You can use basic GA instances to accelerate content delivery at Layer 3 (IP protocols). To implement the acceleration, you need only to specify an acceleration area and an endpoint group. For more information, see Use basic GA instances to accelerate content delivery.
    • Standard: You can use standard GA instances to accelerate content delivery at Layer 4 (TCP and UDP protocols) and Layer 7 (HTTP and HTTPS protocols).
    Accelerated IP Address Type Select the type of accelerated IP address.
    • EIP (default): If you select EIP, the custom access mode is used. You can select an access point based on your business requirements. Each access point provides a separate EIP.
    • Anycast EIP: If you select Anycast EIP, the automatic access mode is used. You do not need to specify an acceleration area. GA provides an Anycast EIP that is shared among multiple regions across the globe.
      Note You can select Anycast EIP only if you set Type to Standard and Specification to Large Ⅰ.

    For more information, see Accelerated IP address.

    Specification Select a specification for the GA instance. You can select a specification for the GA instance only if you set Type to Standard.

    GA provides the following instance specifications: Small Ⅰ (Specifications Unit), Small Ⅱ, Small Ⅲ, Medium Ⅰ, Medium Ⅱ, Medium Ⅲ, Large Ⅰ, Large Ⅱ, Large Ⅲ, Large IV, Large V, Large VI, Large VII, Large VIII, Super Large Ⅰ, and Super Large Ⅱ. GA instances of different specifications provide different acceleration capabilities. For more information, see Specifications of GA instances.

    Instance By default, Instance is selected.
    Subscription Duration Select a subscription duration for the GA instance.

Change the specification of a GA instance

You can change the specifications of standard GA instances. You can only upgrade the specification of a GA instance. To downgrade a GA instance, you must apply for this feature to be enabled on your account. To enable this feature, submit a ticket.

  1. Log on to the Global Accelerator console.
  2. On the Instances page, find the GA instance that you want to manage and click Upgrade in the Actions column.
  3. In the Upgrade message, confirm the information and click OK.
    Note New endpoint group IP addresses may be created after you change the specification of a GA instance. The number of newly created endpoint group IP addresses depends on the GA instance specification. You can go to the console to view the actual number. Make sure that the newly added endpoint group IP addresses are available.
  4. On the Upgrade/Downgrade page, set the parameters, select global accelerator Terms of Service, and then click Buy Now to complete the payment.

    For more information about the acceleration capabilities provided by different specifications, see Specifications of GA instances.
