    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 .

    Examples
    This example creates an Internet-facing load balancer and enables the Availability Zones for the specified subnets.
    Expected Output:
    This example creates an internal load balancer and enables the Availability Zones for the specified subnets.

    :type Name: string
    :param Name: [REQUIRED]
            The name of the load balancer.
            This name must be unique per region per 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 .
