Esempi di Terraform per la VPN ad alta disponibilità su Cloud Interconnect

Puoi utilizzare i seguenti esempi di Terraform per eseguire il deployment della VPN ad alta disponibilità su Cloud Interconnect.

Gli esempi richiedono che tu abbia già eseguito il provisioning di due connessioni Dedicated Interconnect in due domini di disponibilità perimetrale (zone).

Per scoprire come applicare o rimuovere una configurazione Terraform, consulta Comandi Terraform di base.

Esempi

Esempio di 5 Gbps

Il seguente esempio di Terraform esegue il deployment di una VPN ad alta disponibilità tramite il deployment di Cloud Interconnect con due collegamenti VLAN da 5 Gbps.
