Product Advantages¶
Enterprise Edition VPN has the following advantages:
High security
Data is encrypted using IKE/IPsec, ensuring high data security.
A VPN gateway is exclusive to a tenant, isolating tenants from each other.
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.
Active/Standby mode: In normal cases, a VPN gateway communicates with a customer gateway through the active connection. If the active connection fails, traffic is automatically switched to the standby VPN connection. After the fault is rectified, traffic is switched back to the active VPN connection.
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.
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.
Private VPN gateways are supported to encrypt traffic transmitted over Direct Connect connections, improving data transmission security.
Classic VPN has the following advantages:
High security
Dedicated devices are used to encrypt data through IKE and IPsec protocols, offering carrier-class reliability and ensuring stable VPN connections from perspectives of hardware, software, and links.
Seamless scaling
You can connect your on-premises data center to your VPC to quickly extend services at the local data center to the cloud, forming a hybrid cloud.
Cost-effectiveness
IPsec connections over the Internet provide a cost-effective alternative to Direct Connect.
