    Creates a Classic Load Balancer.
    You can add listeners, security groups, subnets, and tags when you create your load balancer, or you can add them later using  CreateLoadBalancerListeners ,  ApplySecurityGroupsToLoadBalancer ,  AttachLoadBalancerToSubnets , and  AddTags .
    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 Classic Load Balancer in the Classic Load Balancer Guide .

    :type LoadBalancerName: string
    :param LoadBalancerName: [REQUIRED]
            The name of the load balancer.
            This name must be unique within your set of load balancers for the region, must have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and cannot begin or end with a hyphen.
            

    :type Listeners: list
    :param Listeners: [REQUIRED]
            The listeners.
            For more information, see Listeners for Your Classic Load Balancer in the Classic Load Balancer Guide .
            (dict) --Information about a listener.
            For information about the protocols and the ports supported by Elastic Load Balancing, see Listeners for Your Classic Load Balancer in the Classic Load Balancer Guide .
            Protocol (string) -- [REQUIRED]The load balancer transport protocol to use for routing: HTTP, HTTPS, TCP, or SSL.
            LoadBalancerPort (integer) -- [REQUIRED]The port on which the load balancer is listening. On EC2-VPC, you can specify any port from the range 1-65535. On EC2-Classic, you can specify any port from the following list: 25, 80, 443, 465, 587, 1024-65535.
            InstanceProtocol (string) --The protocol to use for routing traffic to instances: HTTP, HTTPS, TCP, or SSL.
            If the front-end protocol is HTTP, HTTPS, TCP, or SSL, InstanceProtocol must be at the same protocol.
            If there is another listener with the same InstancePort whose InstanceProtocol is secure, (HTTPS or SSL), the listener's InstanceProtocol must also be secure.
            If there is another listener with the same InstancePort whose InstanceProtocol is HTTP or TCP, the listener's InstanceProtocol must be HTTP or TCP.
            InstancePort (integer) -- [REQUIRED]The port on which the instance is listening.
            SSLCertificateId (string) --The Amazon Resource Name (ARN) of the server certificate.
            
            

    :type AvailabilityZones: list
    :param AvailabilityZones: One or more Availability Zones from the same region as the load balancer.
            You must specify at least one Availability Zone.
            You can add more Availability Zones after you create the load balancer using EnableAvailabilityZonesForLoadBalancer .
            (string) --
            

    :type Subnets: list
    :param Subnets: The IDs of the subnets in your VPC to attach to the load balancer. Specify one subnet per Availability Zone specified in AvailabilityZones .
            (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 type of a load balancer. Valid only for load balancers in a VPC.
            By default, Elastic Load Balancing creates an Internet-facing load balancer with a DNS name that resolves to public IP addresses. For more information about Internet-facing and Internal load balancers, see Load Balancer Scheme in the Elastic Load Balancing User Guide .
            Specify internal to create a load balancer with a DNS name that resolves to private IP addresses.
            

    :type Tags: list
    :param Tags: A list of tags to assign to the load balancer.
            For more information about tagging your load balancer, see Tag Your Classic Load Balancer in the Classic Load Balancer Guide .
            (dict) --Information about a tag.
            Key (string) -- [REQUIRED]The key of the tag.
            Value (string) --The value of the tag.
