The following code examples show how to use CreateLoadBalancer.

CLI
AWS CLI

To create an HTTP load balancer

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

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" --subnets subnet-15aaab61 --security-groups sg-a61988c3

Output:

{
    "DNSName": "my-load-balancer-1234567890.us-west-2.elb.amazonaws.com"
}

This example creates a load balancer with an HTTP listener in EC2-Classic.

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" --availability-zones us-west-2a us-west-2b

Output:

{
    "DNSName": "my-load-balancer-123456789.us-west-2.elb.amazonaws.com"
}

To create an HTTPS load balancer

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

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" "Protocol=HTTPS,LoadBalancerPort=443,InstanceProtocol=HTTP,InstancePort=80,SSLCertificateId=arn:aws:iam::123456789012:server-certificate/my-server-cert" --subnets subnet-15aaab61 --security-groups sg-a61988c3

Output:

{
    "DNSName": "my-load-balancer-1234567890.us-west-2.elb.amazonaws.com"
}

This example creates a load balancer with an HTTPS listener in EC2-Classic.

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" "Protocol=HTTPS,LoadBalancerPort=443,InstanceProtocol=HTTP,InstancePort=80,SSLCertificateId=arn:aws:iam::123456789012:server-certificate/my-server-cert" --availability-zones us-west-2a us-west-2b

Output:

{
    "DNSName": "my-load-balancer-123456789.us-west-2.elb.amazonaws.com"
}

To create an internal load balancer

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

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" --scheme internal --subnets subnet-a85db0df --security-groups sg-a61988c3

Output:

{
    "DNSName": "internal-my-load-balancer-123456789.us-west-2.elb.amazonaws.com"
}

Example 1: This example creates a load balancer with an HTTP listener in a VPC.

$httpListener = New-Object Amazon.ElasticLoadBalancing.Model.Listener
$httpListener.Protocol = "http"
$httpListener.LoadBalancerPort = 80
$httpListener.InstanceProtocol = "http"
$httpListener.InstancePort = 80
New-ELBLoadBalancer -LoadBalancerName my-vpc-load-balancer -SecurityGroup sg-a61988c3 -Subnet subnet-15aaab61 -Listener $httpListener

my-vpc-load-balancer-1234567890.us-west-2.elb.amazonaws.com

Example 2: This example creates a load balancer with an HTTP listener in EC2-Classic.

New-ELBLoadBalancer -LoadBalancerName my-classic-load-balancer -AvailabilityZone us-west-2a` -Listener $httpListener

Output:

my-classic-load-balancer-123456789.us-west-2.elb.amazonaws.com

Example 3: This example creates a load balancer with an HTTPS listener.

$httpsListener = New-Object Amazon.ElasticLoadBalancing.Model.Listener
$httpsListener.Protocol = "https"
$httpsListener.LoadBalancerPort = 443
$httpsListener.InstanceProtocol = "http"
$httpsListener.InstancePort = 80 
$httpsListener.SSLCertificateId="arn:aws:iam::123456789012:server-certificate/my-server-cert"
New-ELBLoadBalancer -LoadBalancerName my-load-balancer -AvailabilityZone us-west-2a -Listener $httpsListener

my-load-balancer-123456789.us-west-2.elb.amazonaws.com
