VPN Gateway is an Internet-based service that securely and reliably connect enterprise data centers, enterprise office networks or Internet terminals to Alibaba Cloud VPCs through encrypted channels. VPN Gateway supports both IPsec-VPN connection and SSL-VPN connection.
IPsec-VPN provides site-to-site VPN connection. You can use IPsec-VPN to connect a VPC to a local data center or connect two VPCs. IPsec-VPN supports IKEv1 protocol and IKEv2 protocol. Any device that supports these two protocols can connect to Alibaba Cloud VPN Gateway. Devices supporting both protocols include those from Huawei, H3C, Hillstone, Sangfor, Cisco, ASA, Juniper, SonicWall, Nokia, IBM, and Ixia.
You can create an SSL-VPN connection to connect a remote client to applications deployed in a VPC. When the deployment is complete, you only need to load the certificate in the client to initiate the connection.
VPN Gateway offers the following benefits:
High security: You can use IKE and IPsec protocols to encrypt transmitted data to ensure data security and reliability.
High availability: Using the active/standby hot backup architecture, VPN Gateway automatically goes into the failover mode within one second. This will have minimal effect on the processing of client data.
Low cost: The Internet-based encrypted channel is more cost-effective than the leased line so that you can rapidly build a hybrid cloud.
Easy to use: Out-of-the-box configurations that take effect immediately allow you to rapidly complete the deployment.
