Product Advantages

VPN has the following advantages:

  • High security
    • Data is encrypted using IKE/IPsec or SSL, ensuring high data security.
    • A VPN gateway is exclusive to a tenant, isolating tenants from each other.
    • Multiple encryption algorithms such as AES and SM series algorithms are supported, meeting a range of security requirements.
    • Multiple authentication modes are supported, including certificate authentication and password authentication.
  • High availability
    • A VPN gateway provides two IP addresses to establish dual independent VPN connections with a customer gateway. If one VPN connection fails, traffic can be quickly switched to the other VPN connection.
    • Active-active gateways are deployed in different availability zones (AZs) to ensure AZ-level high availability.
    • High availability (HA) mode: S2C VPN supports active/standby and active-active modes. P2C VPN supports the active/standby mode.
  • Cost-effectiveness
    • IPsec connections over the Internet provide a cost-effective alternative to Direct Connect.
    • A VPN gateway can be bound to elastic IP addresses (EIPs) that share bandwidth, reducing bandwidth costs.
    • The bandwidth can be adjusted when an EIP instance is created.
    • Access via non-fixed IP addresses reduces access costs in typical scenarios.
  • Easy to use
    • A VPN gateway supports multiple connection modes, including policy-based, static routing, and BGP routing, to meet different access requirements of customer gateways.
    • A VPN gateway on the cloud can function as a VPN hub, enabling on-premises branch sites to access each other.
    • A VPN connection can be created in a few simple steps on the VPN device in an on-premises data center and on the VPN console, and is ready to use immediately after being created.
    • VPN can be used together with the enterprise router service, allowing enterprises to build more flexible cloud-based networks.
    • Backup between VPN and Direct Connect is supported, and automatic failover is supported.
    • Private VPN gateways are supported to encrypt traffic transmitted over Direct Connect connections, improving data transmission security.
    • Terminals running different operating systems, including Windows, macOS, Linux, Android, and iOS, can access the cloud network to implement mobile office.
