NAT Gateway

A high-performance Internet traffic gateway service that fulfills massive volumes of Internet access requests

Overview

NAT Gateway (NG) is a network cloud service that supports IP address translation and enables high-performance Internet access for resources in Tencent Cloud. With the help of NG, Tencent Cloud resources are able to access the Internet more securely without exposing private network information to the Internet. NG can fulfill high volumes of Internet access requests, supporting up to 10 million concurrent connections. Moreover, it offers IP-level traffic control through which you can view traffic data in real time for faster identification of exceptional traffic and easier network troubleshooting.

Benefits

Support for Massive Volumes of Concurrent Requests

NG supports massive volumes of concurrent requests (up to 10 million concurrent connections), making it ideal for scenarios with high volumes of Internet access requests such as video services, Internet of Things and big data analytics.

High-performance Access

For businesses with high Internet access frequency and high bandwidth requirements, NG supports forwarding at over 5 Gbps with 10 elastic IPs bound simultaneously, enabling you to easily cope with peak traffic and ensuring the service reliability of large-scale Internet applications.

Visual Management

NG features traffic control, graphic display of gateway performance status, multi-dimensional monitoring and advance alerting for faults, helping you quickly locate and solve problems as they occur.

Stability and High Availability

The underlying layer of NG features a high-reliability design combining dual-server hot backup and automatic disaster recovery, offering a service availability up to 99.99% and ensuring the stable operation of your business.

Better Cost-effectiveness

Tencent Cloud provides a variety of on-demand NAT gateways that allow you to choose the most appropriate services based on your business needs. In addition, NG supports Bandwidth Package (BWP) for a flexible mix-and-match experience, helping you reduce business costs.

Service Integration

NG can be integrated with other Tencent Cloud services such as BGPAntiDDoS and BWP, helping you build a complete end-to-end cloud network solution.

Features

NG offers a variety of functions such as SNAT, DNAT, gateway traffic control, traffic alarming, BWP, high security defense and automatic disaster recovery.
SNAT

Source Network Address Translation (SNAT) makes it possible for multiple CVMs on VPC to actively access the Internet through the same public IP address.

Scenarios

Massive Volumes of Internet Access Requests

NG is able to provide connection services for high volumes of concurrent requests, supporting up to 10 million concurrent connections and 10 elastic IPs and offering a service availability up to 99.99%, making it ideal for services with large amounts of requests and connections (such as web crawlers).

Secure Access to the Internet

The SNAT function of NG allows for a secure address translation for active Internet access by the CVM, eliminating the potential network security breaches caused by direct exposure of the CVM's public IP to the Internet. Meanwhile, NG can also prevent external services from actively connecting to the CVM, ensuring cloud resource security.

Pricing

NG is charged based on both gateway usage (per hour) and traffic generated from Internet access. NG has different hourly rates based on the NAT gateway specs used and region of service.
