DNS

Diagrammi dell’architettura DNS che coprono i flussi di risoluzione ricorsiva, il bilanciamento del carico globale dei server e la gestione DNS di F5 Distributed Cloud.

Flusso di Risoluzione DNS

Risoluzione standard delle query DNS dal client attraverso il resolver ricorsivo fino al nameserver autorevole con integrazione GSLB.

Gestione DNS F5 XC

Gestione DNS di F5 Distributed Cloud che fornisce bilanciamento del carico DNS intelligente tra origini multi-cloud.

Architettura di Bilanciamento del Carico DNS

Bilanciamento del carico DNS multi-livello con routing geografico, controlli di integrità e failover tra regioni cloud.
