Virtual Private Network¶
Overview¶
A Virtual Private Network (VPN) establishes an encrypted, Internet-based communications tunnel between your on-premises data center and a Virtual Private Cloud (VPC). With VPN, you can connect to a VPC and access the resources deployed there from your data center.
By default, ECSs in a VPC cannot communicate with your data center or private network. To enable communications between them, use a VPN.
A VPN consists of a VPN gateway and one or more VPN connections. A VPN gateway provides an Internet egress for a VPC and works together with the remote gateway in an on-premises data center. A VPN connection uses the Internet-based encryption technology to connect a VPN gateway and a remote gateway to establish cross-premises connectivity between your data center and your VPC. The VPN connection allows you to quickly build secure hybrid cloud environment.
