VPN Connection
An Internet-based encrypted tunneling service that makes it easy to establish secure tunnels between Tencent Cloud and corporate IDCs
Overview
Tencent Cloud VPN Connection is a network-based tunneling technology that enables data transfer between customer local IDCs and Tencent Cloud resources and quick establishment of a secure, reliable and encrypted tunnel on the Internet. Featuring simple configuration, in-cloud configuration with immediate effect, high reliability and gateway availability of 99.95%, it ensures stable and uninterrupted business connections, helping you easily cope with complex business scenarios such as cross-regional disaster recovery and hybrid cloud deployment.
Benefits
Security
The VPN tunnel uses Internet Key Exchange (IKE) protocol and IPsec to encrypt the transmitted data and establish a secure and trusted data connection to the Internet, ensuring security during data transfers.
High Availability
The VPN gateway has a reliability of 99.95%. Its underlying layer adopts a master/slave hot backup architecture which can switch from a faulty instance to a healthy one in a matter of seconds. No tunnel reconstruction is required during switching, ensuring uninterrupted communication sessions and making the switching imperceptible to upper-layer applications.
Visual Management
VPN gateway features traffic control, graphic display of gateway performance status, multi-dimensional monitoring and advance alerting for faults, helping you quickly locate and solve problems as they occur.
Ease of Use
VPN Connection supports out-of-the-box use and in-cloud configuration with immediate effect. The local gateway automatically generates a configuration file which can be imported to the device for instant configuration and quick activation of the VPN service.
Optimal Cost
Both the VPN tunnel and the peer gateway can be used free of charge, with only minimal usage fees for VPN gateway and Internet. VPN Connection supports pay-per-use billing methods, allowing you to choose the most suitable option to reduce costs.
Service Integration
VPN Connection can be integrated with other Tencent Cloud services such as VPC and Direct Connect, helping you build a complete end-to-end solution for your in-cloud businesses.
Features
VPN Gateway
VPN gateway is an egress gateway for creating a VPN connection with a VPC. Together with peer gateway (IPsec VPN service gateway for the IDC), it is mainly used to establish secure, reliable and encrypted network communication between the Tencent Cloud VPC and external IDC. Implemented through software virtualization, it adopts a master/slave hot backup architecture to enable automatic switching when one server fails, ensuring continuous and stable business operation.
Peer Gateway
Peer gateway is a logic object used to record the Internet IP address of the IPsec VPN gateway of the IDC that must be used together with Tencent Cloud VPN gateway. Encrypted VPN network tunnels can be established between one VPN gateway and multiple peer gateways.
VPN Tunnel
Once the VPN gateway and the peer gateway are connected, a VPN tunnel is established for encrypted communication between the VPC and the external IDC. VPN tunnel currently supports the IPsec encryption protocol which can meet the needs of most VPN connections.
Gateway Traffic Control
The traffic control feature of VPN gateway provides "monitoring" and "control" capabilities at the IP-gateway granularity, enabling refined gateway traffic visualization for straightforward insights into the traffic. In addition, the speed limiting capability helps with the blocking of exceptional traffic.
Traffic Alarming
Custom traffic alarms can be set up to enable advance alerting for risks, with alarm messages automatically sent through email and SMS when a metric exceeds a certain threshold. Monitoring and alarming can be used free of charge, enabling you to quickly locate problems as they occur.
Automatic Disaster Recovery
The VPN gateway has a reliability of 99.95%. Its underlying layer adopts a master/slave hot backup architecture which can switch from a faulty instance to a healthy one in a matter of seconds. No tunnel reconstruction is required during switching, ensuring uninterrupted communication sessions and making the switching imperceptible to upper-layer applications.
Flexible Billing
VPN gateway supports pay-as-you-go billing method, meeting the needs of different types of businesses and allowing you to choose the most suitable option to reduce costs.
