Service network interface card
Updated at：2025-10-16
Baidu AI Cloud service network interface card can map external public services such as BOS into the VPC or mount service domains generated by Service Publishing Points, thereby enabling users to securely and conveniently access these services via the intranet within the VPC or hybrid cloud endpoints.
Before Configuration, you should know:
- Each VPC supports up to 20 SNICs.
- A single SNIC is associated with only one subnet, and its IP address must fall within the subnet's CIDR block.
- Each subnet supports only one SNIC for a specific service.
- Local domain services can be connected to the backend of the SNIC.
- The maximum internal bandwidth for a single service network interface card is 50,000 Mbps.
- The total internal bandwidth of all service network interface cards within a single region must not exceed 500,000 Mbps.
