VPN Gateway
A VPN Gateway is a networking service that provides a secure, encrypted connection between an on-premises network and a cloud-based virtual network, or between multiple virtual networks. It acts as a bridge to enable secure data transmission over the internet, often using protocols like IPsec or SSL/TLS. This technology is commonly offered as a managed service by cloud providers like Azure, AWS, and Google Cloud.
Developers should learn and use VPN Gateways when building hybrid cloud architectures that require secure connectivity between on-premises infrastructure and cloud resources, such as for migrating applications, accessing cloud databases, or implementing disaster recovery solutions. It's essential for scenarios where data privacy and compliance (e.g., GDPR, HIPAA) mandate encrypted connections, and for connecting geographically distributed networks in a cost-effective way compared to dedicated lines.
