/**
 * <p>Creates a NAT gateway in the specified subnet. This action creates a network interface
 *           in the specified subnet with a private IP address from the IP address range of the
 *           subnet. You can create either a public NAT gateway or a private NAT gateway.</p>
 *          <p>With a public NAT gateway, internet-bound traffic from a private subnet can be routed
 *           to the NAT gateway, so that instances in a private subnet can connect to the internet.</p>
 *          <p>With a private NAT gateway, private communication is routed across VPCs and on-premises
 *             networks through a transit gateway or virtual private gateway. Common use cases include
 *             running large workloads behind a small pool of allowlisted IPv4 addresses, preserving
 *             private IPv4 addresses, and communicating between overlapping networks.</p>
 *          <p>For more information, see <a href="https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html">NAT gateways</a> in the <i>Amazon Virtual Private Cloud User Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, CreateNatGatewayCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, CreateNatGatewayCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const command = new CreateNatGatewayCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link CreateNatGatewayCommandInput} for command's `input` shape.
 * @see {@link CreateNatGatewayCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for EC2Client's `config` shape.
