NAT gateways are enterprise-class gateways that provide the Source Network Address Translation (SNAT) and Destination Network Address Translation (DNAT) features. Each NAT gateway provides a throughput capacity of up to 100 Gbit/s. NAT gateways also support cross-zone disaster recovery.
NAT gateways support the SNAT feature. SNAT enables Elastic Compute Service (ECS) instances in a virtual private cloud (VPC) to access the Internet when the ECS instances are not assigned public IP addresses.
NAT gateways support the DNAT feature. DNAT maps elastic IP addresses (EIPs) to ECS instances in a VPC. This way, the ECS instances can receive requests that are sent over the Internet.
-
Easy configuration
You can add or subtract the amount of j server backend as needed to increase the serving capacity of your application.
-
High performance
A NAT gateway is an enterprise-grade Internet gateway that controls the traffic flowing to and from a VPC and provides SNAT and DNAT.
-
High availability
NAT Gateway supports cross-zone deployment, which guarantees high availability and ensures service continuity during a zone failure.
-
Flexible specification adjustment
You can change the specification of your NAT gateway, or the number and specifications of the EIPs associated with the NAT gateway at any time to provide dynamic support for your services.
What is a NAT Gateway?
A NAT Gateway allows instances within a Virtual Private Cloud (VPC) to access the internet while remaining private.
How does a NAT Gateway improve security?
NAT Gateways enable outbound internet traffic for your VPC instances while blocking unsolicited inbound traffic from the internet.
Can I scale my NAT Gateway?
Yes, you can scale your NAT Gateway by increasing its throughput capacity to handle more traffic.
How is a NAT Gateway billed?
NAT Gateway pricing is based on the bandwidth usage and the number of connections.
