public abstract class NatProvider
extends software.amazon.jsii.JsiiObject

NAT providers.

Determines what type of NAT provider to create, either NAT gateways or NAT instance.

Example:

 // Configure the `natGatewayProvider` when defining a Vpc
 NatInstanceProvider natGatewayProvider = NatProvider.instance(NatInstanceProps.builder()
         .instanceType(new InstanceType("t3.small"))
         .build());
 Vpc vpc = Vpc.Builder.create(this, "MyVpc")
         .natGatewayProvider(natGatewayProvider)
         // The 'natGateways' parameter now controls the number of NAT instances
         .natGateways(2)
         .build();

instance

@Stability(Stable)
@NotNull
public static NatInstanceProvider instance(@NotNull
 NatInstanceProps props)

Use NAT instances to provide NAT services for your VPC.

NAT instances are managed by you, but in return allow more configuration.
