In order to connect local infrastructure and Azure, we need to create a connection between the local network and Azure Virtual Network. This connection can be either Point-to-Site (P2S) or Site-to-Site (S2S). As P2S allows access to Azure Virtual Network from a single computer, it's not ideal for a true hybrid cloud, but more as point of access for remote workers.
To set up a true hybrid cloud, we need to create an S2S connection that will allow full communication between our local network and Azure Virtual Network. By doing so, we extend our local network to Azure and can access resources in Azure the same way as we would access resources in a local environment.
Creating an S2S connection can be done in two ways: using a VPN and using ExpressRoute. A VPN will provide communication encryption between two networks. ExpressRoute...
