You can use the NAT Gateway service available on the public cloud platform. This service offers NAT for ECSs in a VPC, allowing these ECSs to access the Internet using an EIP. The SNAT function provided by the NAT Gateway service allows the ECSs in a VPC to access the Internet without requiring an EIP. Additionally, SNAT supports a large number of concurrent connections for the applications requiring a large number of requests and connections. For more information about NAT Gateway, see NAT Gateway Service Overview.
