Concepts
1. Virtual Network (VNet) Peering:
VNet peering enables connecting Azure virtual networks in the same region or across different regions, allowing resources in different VNets to communicate with each other using private IP addresses. To connect an on-premises network to an Azure VNet using VNet peering, you can set up a Virtual Network Gateway (VNG) on each side and establish a VPN tunnel between them. This approach ensures secure connectivity by leveraging the Azure VPN gateway services.
Connect Azure VNet to On-Premises Network using VNet Peering
1. Set up a Virtual Network Gateway (VNG) in Azure VNet.
2. Configure the Virtual Network Gateway (VNG) on the on-premises network.
3. Establish a VPN tunnel between the VNGs on each side.
4. Verify the connectivity between Azure VNet and the on-premises network.
2. Azure ExpressRoute:
Azure ExpressRoute is a dedicated private connection that provides a high-bandwidth, low-latency link between an on-premises network and Azure. It offers a more reliable and consistent connection, especially for organizations with rigorous network requirements. ExpressRoute can be directly connected to an Azure VNet using private peering or indirectly connected using Microsoft peering.
Connect Azure to On-Premises Network using ExpressRoute
1. Provision an ExpressRoute circuit in the Azure portal.
2. Engage an ExpressRoute connectivity provider to establish the physical connection.
3. Configure the ExpressRoute circuit with appropriate routing.
4. Set up a Virtual Network Gateway (VNG) in Azure VNet.
5. Verify the connectivity between Azure VNet and the on-premises network.
3. Site-to-Site VPN:
A Site-to-Site VPN establishes a secure connection between on-premises networks and Azure VNets over the Internet. It allows resources in Azure and on-premises networks to communicate securely using IPsec/IKE VPN tunnels. To set up a Site-to-Site VPN, you need to configure a VPN gateway in Azure and a compatible VPN device on the on-premises network.
Connect Azure to On-Premises Network using Site-to-Site VPN
1. Configure a Virtual Network Gateway (VNG) in Azure VNet.
2. Obtain the necessary VPN device information for the on-premises network.
3. Set up the VPN device on the on-premises network.
4. Configure the Site-to-Site VPN settings in Azure.
5. Establish the VPN tunnel and verify connectivity between Azure VNet and the on-premises network.
4. Azure Virtual WAN:
Azure Virtual WAN simplifies network connectivity for large-scale deployments by providing an automated and optimized branch-to-branch and branch-to-Azure connectivity using site-to-site VPN, ExpressRoute, or both. It allows you to connect your on-premises networks to Azure resources securely and efficiently, while also providing robust network management capabilities.
Connect Azure to On-Premises Network using Azure Virtual WAN
1. Provision an Azure Virtual WAN resource in the Azure portal.
2. Create and configure a Virtual WAN hub.
3. Set up the VPN device on your on-premises network.
4. Establish a connection between the on-premises network and the Azure Virtual WAN hub.
5. Verify the connectivity between Azure resources and the on-premises network.
Each of these connectivity options offers unique features and benefits based on specific requirements. It is important to evaluate them and choose the solution that aligns best with your organization’s needs when connecting Azure resources to on-premises networks.
