NAT Gateway SNAT EIP Bandwidth Consistency

ID: rule:aliyun:natgateway-snat-eip-bandwidth-check
Severity: medium
IaC Types: ROS, Terraform

Description​

NAT gateway specification should not be Small to ensure adequate SNAT EIP bandwidth capacity.

Reason for Violation​

Small specification NAT gateways may not provide sufficient bandwidth for SNAT entries with multiple EIPs, leading to performance issues.

Recommendation​

Set specification to 'Middle' or higher to ensure adequate bandwidth for SNAT EIP traffic.
