NAT Gateway

NAT Gateway is the gateway for a VPC to access internet traffic, and provides proxy forwarding services by configuring SNAT and DNAT entries flexibly. It supports IP mapping and port mapping.

Value Proposition

Flexible and Easy-to-use

There’s no need for users to construct a gateway on their own servers. The console flexibly defines various NAT rules, easy and reliable.

Low Cost

Change the bandwidth and the number of the public IPs at any time according to business needs; pay-as-you-go is adopted, with cheap prices.

High Availability

NAT Gateway supports deployment in multiple Availability Zones, with a multi-level highly available architecture developed in-house, to ensure the stable and reliable operation of the gateway.

Heavy Traffic and High Concurrency

NAT gateways support heavy traffic and high concurrency, up to 10 million concurrent connections, effectively coping with high-volume traffic of public network.

Use Cases

Massive Request for Access to the Public Network

NAT gateway can provide an ultra-large number of concurrent connections, up to 10 million concurrent connections, and 10 flexible IPs, with availability up to 99.99%, suitable for services with a large number of requests and connections (such as web crawlers).
Recommend to use with: Elastic Compute Service Virtual Private Cloud

Secure Access to the Public Network

The SNAT function of the NAT gateway provides a secure address translation for the ECS to access the public network, thus avoiding network security risks caused by the direct exposure of the public network IP of the ECS to the internet. At the same time, using NAT gateways can also prevent ECS from being actively connected by the external to ensure security of resources on the cloud.

Functionality

SNAT

The ECS host in the same VPC accesses the internet through the same public network address or address pool to avoid the security risks caused by direct exposure of the public IP address by the ECS host.
DNAT

Port mapping: An application of a port on an ECS host within a VPC can be mapped into a port of the public IP address.IP mapping: Map the services provided by the external network IP back to the ECS host within the VPC.
