# VPN Gateway Overview Azure VPN Gateway is a service that enables encrypted traffic to be sent securely between Azure a [[Virtual Network]] and on-premises locations over the Internet. It also allows secure connectivity between virtual networks within Azure using VPN tunnels. ![VPN Gateway](https://learn.microsoft.com/en-us/azure/vpn-gateway/media/tutorial-create-gateway-portal/gateway-diagram-expand.png) # VPN Gateway Key Features - Supports multiple VPN protocols, including OpenVPN for point-to-site connections. - Offers active-active configurations to increase throughput and reliability. - Capable of supporting both site-to-site and point-to-site VPN types for flexible connectivity options. - Facilitates coexisting connections with ExpressRoute for improved resiliency and redundancy. # Importance of VPN Gateway Using Azure VPN Gateway is crucial for ensuring secure and reliable connectivity for hybrid cloud architectures. It allows organizations to extend their on-premises networks into the cloud securely and enables smooth interconnectivity between distributed cloud resources. This improves access to services, supports hybrid applications, and ensures data integrity across multiple environments. # Use Cases for VPN Gateway - **Hybrid Cloud Implementations:** Connect on-premises networks to Azure securely to enable seamless hybrid cloud solutions. - **Multi-VNet Architecture:** Facilitate secure communication between different virtual networks in Azure to implement complex application architectures. - **Remote Workforce Enablement:** Support remote workers by enabling secure point-to-site connections to Azure VNets from any location. - **Business Continuity:** Implement as a failover to ensure connectivity during primary link failures by integrating with ExpressRoute. - **Global Application Deployment:** Connect globally distributed applications across multiple Azure regions with secure VNet-to-VNet tunnels.
