Your network address translation gateway in order to connect internet to your network
Flexible Engine / Network
The NAT Gateway service can be deployed flexibly across subnets and across AZs. Any fault in a single AZ does not affect the service continuity of NAT Gateway. The types and public IP address of a NAT gateway can be adjusted at any time.
Diversified and easy-to-use
Multiple types of NAT gateways are available. User can use them after simply configuring them. NAT gateways support easy operation and maintenance (O&M) and quick provisioning. They can run stably and reliably.
Multiple ECSs share an elastic IP address. When you send data through a private IP address or provide services for the Internet using a NAT gateway, the NAT Gateway service translates the private IP address to a public IP address. Users do not need to purchase additional EIPs and bandwidth resources for their ECSs to access the Internet.
The NAT Gateway service offers the Network Address Translation (NAT) function for Elastic Cloud Servers (ECSs) in a Virtual Private Cloud (VPC), allowing these ECSs to access the Internet using elastic IP addresses (EIPs) or to provide services for external networks.
Application scenario: Public Network Egress
NAT Gateway constructs a public network egress for a VPC. Computing instances of that VPC can use shared EIPs to access the Internet. Multiple types of NAT gateways are available.
