Anycast addressing is utilized to support the connection of multiple application connectors fronting an application(s) to a network element and anycast routing of network traffic destined for the application(s). When an application is indicated for onboarding in a tenant's network fabric, a network controller allocates virtual and anycast addresses to the application. Allocation of anycast addresses is per domain name and port/protocol combination. Upon determining that the application is available, the application connector(s) advertises reachability of the application via the anycast address. The network controller orchestrates configuration of a domain name system entry that resolves the application name to its virtual Internet Protocol (IP) address and destination network address translation rules that translate the virtual IP address to the anycast address and the anycast address to the application's private IP address. Application network traffic can thus be forwarded to the application via any application connector that advertised the anycast address.
