Understanding Azure Virtual WAN

Azure Virtual WAN is a networking service in Microsoft Azure designed to optimize and simplify connectivity for enterprises with distributed branch offices, remote users, and cloud resources. It provides a unified hub-and-spoke architecture, enabling organizations to connect, secure, and manage their networks with unprecedented ease.

Key Components of Azure Virtual WAN:

• Hubs: Centralized network locations where connectivity policies are configured and enforced. Hubs serve as the control points for managing traffic and security.

• Spokes: Branch offices, remote users, or cloud resources that connect to the hubs. Spokes benefit from simplified connectivity and consistent network policies.

• Virtual WAN: The overarching networking infrastructure that brings together hubs and spokes, offering a unified and optimized network topology.

Connectivity Principles:

• Site-to-Site VPNs: Virtual WAN facilitates secure connectivity between on-premises locations and Azure through site-to-site VPNs. This is particularly valuable for organizations with distributed branch offices.

• Point-to-Site VPNs: Remote users can securely connect to the Azure network using point-to-site VPNs, ensuring a seamless and protected experience for employees working from various locations.

• ExpressRoute Integration: For high-throughput and dedicated connectivity, Azure Virtual WAN seamlessly integrates with Azure ExpressRoute, providing a private connection to Azure services.
