VPN Gateway is an Internet-based service that securely and reliably connects enterprise data centers, office networks, and Internet terminals to Alibaba Cloud VPCs through encrypted channels. VPN Gateways provides flexible configurations to meet the demands of different scenarios.
Connect a VPC to an on-premises data center
You can connect an on-premises data center to a VPC to build a hybrid cloud through the following two ways:
The route-based IPsec-VPN not only facilitates the configuration and maintenance of VPN policies, but also provides flexible traffic routing methods. For more information, see Establish a connection between a VPC and an on-premises data center.
Interconnect two VPCs
You can rapidly interconnect two VPCs through IPsec-VPN.
The route-based IPsec-VPN not only facilitates the configuration and maintenance of VPN policies, but also provides flexible traffic routing methods. For more information, see Establish a connection between two VPCs.
Connect a remote client to a VPC
You can connect a client to a VPC through an SSL-VPN tunnel to meet the needs of remote working. With SSL-VPN connections, you can securely access a VPC through the Internet at anytime, anywhere.
SSL-VPN connections support remote access from clients running Windows, Linux, Mac, IOS, or Android operating system.
Hub Spoke connection
You can establish secure communications among multiple sites by using the Hub Spoke function to interconnect the sites through the VPN Gateway of the VPC. Hub Spoke can meet the needs of large enterprises to establish intranet communication between office sites.
For more information, see Hub Spoke connection.
Use IPsec-VPN and SSL-VPN together
You can use IPsec-VPN and SSL-VPN connections together to expand your network topology. Once the connections are established, the client can access the applications deployed in the connected VPC, and can also access the applications deployed in the connected office sites.
