High-performance public traffic ingress and egress to meet your Internet access requirements
Overview
NAT Gateway is a cloud network service that provides the IP address translation feature. It provides high-performance Internet access capabilities for resources that are deployed on the cloud platform. NAT Gateway can help you connect your resources on the cloud platform to the Internet in a more secure manner and protect the information of your virtual private cloud (VPC) from being exposed to the public network. NAT Gateway supports a maximum of 10 million concurrent connections to the Internet. It also supports traffic throttling at the IP address level, which allows you to view real-time statistics of traffic that flows through your NAT gateway and helps you locate abnormal traffic and troubleshoot network failures.
NAT Gateway supports up to 10 million concurrent connections. It can handle massive amounts of access over the Internet in various scenarios, such as video services, Internet of Things (IoT), and big data analysis.
NAT gateways can be used to support businesses that frequently access the Internet and that require high bandwidth. A NAT gateway can provide a forwarding capability of up to 5 Gbit/s and support up to 10 elastic IP addresses (EIPs) to handle traffic spikes. Therefore, you can use NAT gateways to support applications that are accessed by large amounts of traffic over the Internet.
NAT Gateway provides the traffic throttling feature. The gateway performance is monitored in multiple dimensions, and the performance monitoring data is displayed on charts. You can set alarm rules and can locate and troubleshoot issues in a quick manner based on the alarms that you received.
The high-reliability design of NAT Gateway (active-active hot backup and automatic disaster recovery) raises its service availability to 99.99%, safeguarding the stable running of your businesses.
NAT Gateway provides gateways in different specifications for different business requirements. Besides, NAT Gateway supports bandwidth packages. You can configure your NAT gateway based on your business requirements to reduce costs.
NAT Gateway can be integrated with other cloud services such as Anti-DDoS and Bandwidth Package (BWP) to provide end-to-end cloud network solutions.
A NAT gateway can support up to 10 million concurrent connections and up to 10 EIPs, and provides a service availability of up to 99.99%. Therefore, you can use NAT gateways for services that process a large number of requests and connections, such as web crawler systems.
The Source Network Address Translation (SNAT) feature of NAT Gateway can translate IP addresses of Cloud Virtual Machine instances (CVMs) that access the Internet to avoid security risks that may be caused by exposing the public IP addresses of the CVMs to the public network. NAT Gateway can also stop connections from external networks to your CVMs. This helps ensure the security of your cloud resources.
