Azure VPN Gateway
Azure VPN Gateway is a cloud-based service that enables secure, encrypted connections between Azure virtual networks and on-premises networks or other Azure virtual networks over the public internet. It acts as a virtual network gateway that routes traffic through site-to-site, point-to-site, or VNet-to-VNet VPN tunnels using industry-standard protocols like IPsec and IKE. This service is essential for hybrid cloud architectures, allowing organizations to extend their on-premises infrastructure to Azure securely.
Developers should learn Azure VPN Gateway when building hybrid cloud solutions that require secure connectivity between Azure resources and on-premises data centers, branch offices, or remote users. It is particularly useful for scenarios like migrating workloads to Azure while maintaining access to legacy systems, implementing disaster recovery with failover to the cloud, or enabling remote employees to access Azure-hosted applications via point-to-site VPNs. Using Azure VPN Gateway ensures encrypted, reliable network integration without the need for physical hardware, simplifying deployment and management compared to traditional VPN appliances.
