NAT Gateway Advantages

Updated on 2025-01-10 GMT+08:00

Advantages of Public NAT Gateways

  • Flexible deployment

    A NAT gateway can be shared across subnets and AZs, so that even if an AZ fails, the public NAT gateway can still run normally in another AZ. The specifications and EIP of a public NAT gateway can be changed at any time.

  • Ease of use

    Multiple NAT gateway specifications are available. Public NAT gateway configuration is simple, the operation & maintenance is easy, and they can be provisioned quickly. Once provisioned, they can run stably.

  • Cost-effectiveness

    Servers can share one EIP to connect to the Internet. You no longer need to configure one EIP for each server, which saves money on EIPs and bandwidth.

Advantages of Private NAT Gateways

  • Easier network planning

    Different departments in a large enterprise may have overlapping CIDR blocks, so the enterprise has to replan its network before migrating their workloads to the cloud. The replanning is time-consuming and stressful. The private NAT gateway eliminates the need to replan the network so that customers can retain their original network while migrating to the cloud.

  • Easy operation & maintenance

    Departments of a large enterprise usually have hierarchical networks for hierarchical organizations, rights- and domain-based management, and security isolation. Such hierarchical networks need to be mapped to a large-scale network for enabling communication between them. A private NAT gateway can map the CIDR block of each department to the same VPC CIDR block, which simplifies the management of complex networks.

  • Strong security

    Departments of an enterprise may need different levels of security. Private NAT gateways can expose the IP addresses and ports of only specified CIDR blocks to meet high security requirements. An industry regulation agency may require other organizations to use a specified IP address to access their regulation system. Private NAT gateways can help meet this requirement by mapping private IP addresses to that specified IP address.

  • Zero IP conflicts

    Isolated services of multiple departments usually use IP addresses from the same private CIDR block. After the enterprise migrates workloads to the cloud, IP address conflicts occur. Thanks to IP address mapping, the private NAT gateways allow for communication between overlapping CIDR blocks.
