Before you use Global Traffic Manager (GTM), you must purchase a GTM instance.
If multiple domain names are mapped to the same IP address of your service, you can add canonical name (CNAME) records for these domain names. The CNAME records map the domain names to the CNAME assigned to the same GTM instance. Otherwise, you need to purchase a GTM instance for each domain name.
Procedure
Log on to the Alibaba Cloud DNS console.
In the left-side navigation pane, click Global Traffic Manager.
On the Global Traffic Manager page, click Create Instance.
On the buy page of the GTM instance, select an edition based on your business requirements and the description in the Specifications section. Click Buy Now and complete the payment.
After the payment is complete, the GTM instance is automatically displayed on the Global Traffic Manager page.
