Azure Route Server

Azure Virtual Network gives you an isolated and highly-secure environment to run your virtual machines and applications. Use your private IP addresses and define subnets, access control policies, and more. Use Virtual Network to treat Azure the same as you would your own datacenter. Traffic between Azure resources in a single region, or in multiple regions, stays in the Azure network—intra-Azure traffic doesn’t flow over the Internet. In Azure, traffic for virtual machine-to-virtual machine, storage, and SQL communication only traverses the Azure network, regardless of the source and destination Azure region. Inter-region virtual network-to-virtual network traffic also flows entirely across the Azure network. Use Virtual Network to extend your on-premises IT environment into the cloud, like you set up and connect to a remote branch office. You have options to securely connect to a virtual network—choose an IPsec VPN or a private connection by using Azure ExpressRoute.

Azure Private Link provides private connectivity from a virtual network to Azure platform as a service (PaaS), customer-owned, or Microsoft partner services. It simplifies the network architecture and secures the connection between endpoints in Azure by eliminating data exposure to the public internet. Private connectivity to services on Azure—traffic remains on the Microsoft network, with no public internet access. Use Private Link to bring services delivered on Azure into your private virtual network by mapping it to a private endpoint. Or privately deliver your own services in your customers’ virtual networks. All traffic to the service can be routed through the private endpoint, so no gateways, NAT devices, ExpressRoute or VPN connections, or public IP addresses are needed. Private Link keeps traffic on the Microsoft global network.
