API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the CreateLoadBalancer operation. 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.

Syntax

C#
public class CreateLoadBalancerRequest : AmazonElasticLoadBalancingRequest
         IAmazonWebServiceRequest

The CreateLoadBalancerRequest type exposes the following members

Constructors

NameDescription
Public Method CreateLoadBalancerRequest()

Empty constructor used to set properties independently even when a simple constructor is available

Public Method CreateLoadBalancerRequest(string)

Instantiates CreateLoadBalancerRequest with the parameterized properties

Public Method CreateLoadBalancerRequest(string, List<Listener>, List<String>)

Instantiates CreateLoadBalancerRequest with the parameterized properties

Properties

NameTypeDescription
Public Property AvailabilityZones System.Collections.Generic.List<System.String>

Gets and sets the property 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.

Public Property Listeners System.Collections.Generic.List<Amazon.ElasticLoadBalancing.Model.Listener>

Gets and sets the property Listeners.

The listeners.

For more information, see Listeners for Your Classic Load Balancer in the Classic Load Balancer Guide.

Public Property LoadBalancerName System.String

Gets and sets the property LoadBalancerName.

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.

Public Property Scheme System.String

Gets and sets the property 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.

Public Property SecurityGroups System.Collections.Generic.List<System.String>

Gets and sets the property SecurityGroups.

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

Public Property Subnets System.Collections.Generic.List<System.String>

Gets and sets the property Subnets.

The IDs of the subnets in your VPC to attach to the load balancer. Specify one subnet per Availability Zone specified in AvailabilityZones.

Public Property Tags System.Collections.Generic.List<Amazon.ElasticLoadBalancing.Model.Tag>

Gets and sets the property 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.

Examples

This example creates a load balancer with an HTTP listener in a VPC.
