    Alibaba Cloud DNS:Purchase an instance

    Last Updated:May 30, 2024

    Overview

    Before you can use Global Traffic Manager (GTM), you must purchase a GTM instance.

    Important

    If your business domain names are mapped to the same group of IP addresses, you can configure canonical name (CNAME) records to point these domain names to the access domain name of the same GTM instance. Otherwise, you must purchase a GTM instance for each business domain name.

    Use the same GTM instance for multiple business domain names

    • The business domain name www.cloud-example.com is mapped to the IP addresses 1.1.XX.XX and 2.2.XX.XX, and disaster recovery is required between the two IP addresses.

    • The business domain name test.cloud-example.com is mapped to the IP addresses 1.1.XX.XX and 2.2.XX.XX, and disaster recovery is required between the two IP addresses.

    In this scenario, two business domain names are mapped to the same group of IP addresses. Therefore, you need to purchase only one GTM instance. You need to only configure a CNAME record for each of the business domain names www.cloud-example.com and test.cloud-example.com by specifying an access domain name in GTM as the record value.

    Note

    In this scenario, users generally configure proxies on their application servers to forward requests to different ports that identify different services.

    Use different GTM instances for multiple business domain names

    • The business domain name www.cloud-example.com is mapped to the IP addresses 1.1.XX.XX and 2.2.XX.XX, and disaster recovery is required between the two IP addresses.

    • The business domain name test.cloud-example.com is mapped to the IP addresses 1.1.XX.XX and 3.3.XX.XX, and disaster recovery is required between the two IP addresses.

    In this scenario, two business domain names are mapped to different IP addresses. Therefore, you need to purchase a GTM instance for each of the two business domain names.
