What is the role of a VPN Gateway in Google Cloud?

The role of a VPN Gateway in Google Cloud is to create secure VPN connections. This is essential for organizations that need to connect their on-premises infrastructure or remote networks to their Google Cloud resources securely over the internet. The VPN Gateway establishes a secure tunnel using IPsec protocols, which encrypts the data transmitted between the two endpoints, ensuring that sensitive information remains protected during transit.

By employing a VPN Gateway, organizations can extend their on-premises networks into the cloud seamlessly, integrate with cloud resources, and enable secure communications between environments. This capability supports various use cases, such as hybrid cloud deployments, where businesses require seamless access to both their on-premises and cloud-hosted applications.

While sharing internet access and supporting serverless functions are important aspects of cloud architecture, they do not pertain to the specific function of a VPN Gateway. Additionally, the role of acting as a backup for cloud services is not relevant to the primary purpose of a VPN Gateway, which focuses on enabling secure connectivity rather than data backup or redundancy.
