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.
- Log on to the Global Accelerator console.
- On the Instances page, click Create Instance.
- On the buy page, select the type of the GA instance based on your requirements, set the following parameters, and
then click Buy Now to complete the payment.
- BasicYou can use basic GA instances to accelerate content delivery at Layer 3 (IP protocols). To implement the acceleration, you need to only specify an acceleration area and an endpoint group.
Parameter Description Instance By default, Instance is selected. Subscription Duration Select the subscription duration of the basic GA instance. You can select Auto-renewal to enable auto-renewal for the basic GA instance.
- StandardYou can use standard GA instances to accelerate content delivery at Layer 4 (TCP and UDP) and Layer 7 (HTTP and HTTPS).
Parameter Description Specification Select the specification of the standard GA instance. For more information about the specifications supported by standard GA instances, see Specifications of standard GA instances.
Instance By default, Instance is selected. Accelerated IP Address Type Select the type of accelerated IP address for the standard GA instance. You can specify this parameter only if you select Large Ⅰ or a higher specification. - EIP (default): If you select elastic IP address (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
- By default, you cannot specify Anycast EIPs as accelerated IP addresses. If you want to use Anycast EIPs, submit a ticket.
- If you use Anycast EIPs, the GA instances and basic bandwidth plans must meet the following requirements:
- GA instances: You must select standard GA instances whose specifications are Large Ⅰ or higher.
- Basic bandwidth plans: You must select pay-by-data-transfer basic bandwidth plans whose bandwidth types are Premium. By default, you cannot use pay-by-data-transfer basic bandwidth plans. If you want to use pay-by-data-transfer basic bandwidth plans, submit a ticket.
For more information, see Accelerated IP address.
Subscription Duration Select the subscription duration of the standard GA instance. You can select Auto-renewal to enable auto-renewal for the basic GA instance.
- Basic
Change the specification of a standard GA instance
You can change the specifications of standard GA instances. You can only upgrade standard GA instances. By default, you cannot downgrade standard GA instances. To downgrade standard GA instances, submit a ticket.
