Response

{'LoadBalancers': {'AvailabilityZones': {'SourceNatIpv6Prefixes': ['string']},
                   'EnablePrefixForIpv6SourceNat': 'on | off'}}

Creates an Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.

For more information, see the following:

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple load balancers with the same settings, each call succeeds.

type Subnets

list

param Subnets

The IDs of the subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings, but not both. To specify an Elastic IP address, specify subnet mappings instead of subnets.

[Application Load Balancers] You must specify subnets from at least two Availability Zones.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Network Load Balancers and Gateway Load Balancers] You can specify subnets from one or more Availability Zones.

list

param SubnetMappings

The IDs of the subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings, but not both.

[Application Load Balancers] You must specify subnets from at least two Availability Zones. You can't specify Elastic IP addresses for your subnets.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Network Load Balancers] You can specify subnets from one or more Availability Zones. You can specify one Elastic IP address per subnet if you need static IP addresses for your internet-facing load balancer. For internal load balancers, you can specify one private IP address per subnet from the IPv4 range of the subnet. For internet-facing load balancer, you can specify one IPv6 address per subnet.

[Gateway Load Balancers] You can specify subnets from one or more Availability Zones. You can't specify Elastic IP addresses for your subnets.

param Scheme

The nodes of an Internet-facing load balancer have public IP addresses. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the internet.

The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

The default is an Internet-facing load balancer.

You can't specify a scheme for a Gateway Load Balancer.

type Type

string

param Type

The type of load balancer. The default is application .

type IpAddressType

string

param IpAddressType

The IP address type. Internal load balancers must use ipv4 .

[Application Load Balancers] The possible values are ipv4 (IPv4 addresses), dualstack (IPv4 and IPv6 addresses), and dualstack-without-public-ipv4 (public IPv6 addresses and private IPv4 and IPv6 addresses).

[Network Load Balancers and Gateway Load Balancers] The possible values are ipv4 (IPv4 addresses) and dualstack (IPv4 and IPv6 addresses).

Enables the Availability Zones for the specified public subnets for the specified Application Load Balancer, Network Load Balancer or Gateway Load Balancer. The specified subnets replace the previously enabled subnets.

When you specify subnets for a Network Load Balancer, or Gateway Load Balancer you must include all subnets that were enabled previously, with their existing configurations, plus any additional subnets.

type SubnetMappings

list

param SubnetMappings

The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

[Application Load Balancers] You must specify subnets from at least two Availability Zones. You can't specify Elastic IP addresses for your subnets.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Gateway Load Balancers] You can specify subnets from one or more Availability Zones.

(dict) --

Information about a subnet mapping.
- SubnetId (string) --

  [Network Load Balancers] The allocation ID of the Elastic IP address for an internet-facing load balancer.
- PrivateIPv4Address (string) --
  
  [Network Load Balancers] The private IPv4 address for an internal load balancer.
- IPv6Address (string) --
  
  [Network Load Balancers] The IPv6 address.
- SourceNatIpv6Prefix (string) --
  
  [Network Load Balancers with UDP listeners] The IPv6 prefix to use for source NAT. Specify an IPv6 prefix (/80 netmask) from the subnet CIDR block or auto_assigned to use an IPv6 prefix selected at random from the subnet CIDR block.

type IpAddressType

string

param IpAddressType

The IP address type.

[Network Load Balancers and Gateway Load Balancers] The possible values are ipv4 (IPv4 addresses) and dualstack (IPv4 and IPv6 addresses).

type EnablePrefixForIpv6SourceNat

string

param EnablePrefixForIpv6SourceNat

[Network Load Balancers with UDP listeners] Indicates whether to use an IPv6 prefix from each subnet for source NAT. The IP address type must be dualstack . The default value is off .
