Azure Virtual Network Gateway Improvements

Click to Read

Azure Virtual Network Gateway serves as the cross premises gateway connecting your workloads in Azure Virtual Network to your on premises sites. It is required to connect to on premises sites through IPsec S2S VPN tunnels, or through ExpressRoute circuits. For IPsec/IKE VPN tunnels, the gateway performs the IKE handshakes, and establishes the IPsec S2S VPN tunnels between the on premises sites. For ExpressRoute, the gateways advertise the prefixes in your virtual networks via the peering circuit, and also forward packets from your ExpressRoute circuits to your VMs inside your virtual networks.

Network Security Groups

Last week at TechEd Europe we announced the general availability of Network Security groups, a key addition to the Azure Networking stack. Network Security Groups provides segmentation within a Virtual Network (VNet) as well as full control over traffic that ingresses or egresses a virtual machine in a VNet. It also helps achieve scenarios such as DMZs (demilitarized zones) to allow users to tightly secure backend services such as databases and application servers.
