Enum Constant Detail

ISOLATED

@Stability(value=Experimental)
public static final SubnetType ISOLATED

(experimental) Isolated Subnets do not route traffic to the Internet (in this VPC).

This can be good for subnets with RDS or Elasticache instances, or which route Internet traffic through a peer VPC.

PRIVATE

@Stability(value=Experimental)
public static final SubnetType PRIVATE

(experimental) Subnet that routes to the internet, but not vice versa.

Instances in a private subnet can connect to the Internet, but will not allow connections to be initiated from the Internet. Internet traffic will be routed via a NAT Gateway.

Normally a Private subnet will use a NAT gateway in the same AZ, but if natGateways is used to reduce the number of NAT gateways, a NAT gateway from another AZ will be used instead.

PUBLIC

@Stability(value=Experimental)
public static final SubnetType PUBLIC

(experimental) Subnet connected to the Internet.

Instances in a Public subnet can connect to the Internet and can be connected to from the Internet as long as they are launched with public IPs (controlled on the AutoScalingGroup or other constructs that launch instances).

Public subnets route outbound traffic via an Internet Gateway.

Method Detail

values

public static SubnetType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SubnetType c : SubnetType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SubnetType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
