There are several ways to connect Azure Subscriptions. Before, we were using VPN gateway for connecting different subscriptions Virtual Network to Virtual Network. We can use VNet Peering to connect virtual networks in the same Azure region or different Azure regions. The virtual networks can be in the same Azure subscription or in different subscriptions, as long as they share the same Azure AD tenant. Also now, we can use VNet Peering to connect different Azure AD Tenants. VNet Peering also allows you to connect two virtual networks created by using different deployment models. In this article, I’m going to explain how can we implement VNet Peering across different Azure Active Directory Tenants.
Before we start this article, what exactly we need to implement for this feature. We can configure VNet Peering by using the Azure portal, Azure PowerShell, Azure CLI and also Azure Resource Manager templates.
