    • The instance type of a NAT gateway affects its maximum connections and new connections per second. These metrics include both SNAT and DNAT connections.

    • If you require higher bandwidth, you can switch the billing method from pay-as-you-go (pay-by-specification) to pay-as-you-go (pay-by-CU).

    • In real-world scenarios, the performance of a NAT gateway is affected by multiple factors, such as the average size of network packets, connection type (persistent or short-lived connections), and network architecture. Therefore, the actual performance of an instance may differ from its expected performance. You can perform stress tests to evaluate the instance performance and configure metrics to ensure business continuity.
