VPN Gateway
A VPN Gateway is a networking service that provides secure, encrypted connections between on-premises networks and cloud resources or between different cloud environments. It acts as a virtual router or gateway to establish site-to-site or point-to-site VPN tunnels, enabling private communication over public internet infrastructure. Common implementations include Azure VPN Gateway, AWS VPN Gateway, and Google Cloud VPN.
Developers should learn VPN Gateways when building hybrid cloud architectures that require secure connectivity between on-premises data centers and cloud platforms, or for connecting virtual networks across different cloud providers. They are essential for scenarios like migrating workloads to the cloud while maintaining existing infrastructure, implementing disaster recovery solutions, or ensuring compliance with data residency regulations by encrypting traffic in transit.
