type LoadBalancerArn

string

param LoadBalancerArn

[REQUIRED]

The Amazon Resource Name (ARN) of the load balancer.

string

param IpAddressType

[REQUIRED]

The IP address type. The possible values are ipv4 (for IPv4 addresses) and dualstack (for IPv4 and IPv6 addresses). Internal load balancers must use ipv4 .

Creates an Application Load Balancer.

When you create a load balancer, you can specify security groups, subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups, SetSubnets, SetIpAddressType, and AddTags.

To create listeners for your load balancer, use CreateListener. To describe your current load balancers, see DescribeLoadBalancers. When you are finished with a load balancer, you can delete it using DeleteLoadBalancer.

You can create up to 20 load balancers per region per account. You can request an increase for the number of load balancers for your account. For more information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide .

For more information, see Application Load Balancers in the Application Load Balancers Guide .

type Name

string

param Name

[REQUIRED]

The name of the load balancer.

This name must be unique within your AWS account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.

type Subnets

list

param Subnets

[REQUIRED]

The IDs of the subnets to attach to the load balancer. You can specify only one subnet per Availability Zone. You must specify subnets from at least two Availability Zones.

• (string) --

type SecurityGroups

list

param SecurityGroups

The IDs of the security groups to assign to the load balancer.

• (string) --

type Scheme

string

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 only route requests from clients with access to the VPC for the load balancer.

The default is an Internet-facing load balancer.

type Tags

list

param Tags

One or more tags to assign to the load balancer.

• (dict) --

  Information about a tag.

  • Key (string) -- [REQUIRED]

    The key of the tag.

  • Value (string) --

    The value of the tag.

type IpAddressType

string

param IpAddressType

The type of IP addresses used by the subnets for your load balancer. The possible values are ipv4 (for IPv4 addresses) and dualstack (for IPv4 and IPv6 addresses). Internal load balancers must use ipv4 .
