Abstract
The present disclosure provides a domain name resolution method and apparatus based on a plurality of availability zones (AZ). After receiving, from a client, a domain name resolution request including a domain name of a to-be-accessed resource, a domain name system (DNS) determines, from a plurality of AZs corresponding to the domain name, a first AZ in a service available state, where each of the plurality of AZs is capable of providing the to-be-accessed resource, and then sends an internet protocol (IP) address of the first AZ to the client. In this way, the DNS processes the domain name resolution request sent by the client. After receiving the domain name resolution request sent by the client, the DNS feeds back, to the client, an IP address that is of an AZ in the service available state and that corresponds to the domain name resolution request.
