Network Load Balancer

Create a VPC

You can launch HAProxy Enterprise instances in a Virtual Private Cloud (VPC), which is a virtual network similar to a traditional network.

1. Open the Amazon VPC console, then click Launch VPC Wizard.

   

2. Create a VPC with a single, public subnet with the following characteristics.

   

   Field	Value
   Public subnet's Availability Zone	The availability zone of your choice, for example, eu-west-3a.

   In other fields, keep the default values or select other values that better suit your needs.

3. In the Virtual Private Cloud section on the left, select Your VPCs, then write down the ID of the new VPC.

   

   For example, vpc-0deecc96935b9ef73.

Deploy HAProxy Enterprise AMIs

You can launch HAProxy Enterprise instances directly from the AWS Marketplace.

• Create two or more HAProxy Enterprise instances on AWS, with the following characteristics.

  

  Field	Value
  Software version
  Region	Region to which your Availability Zone belongs.
  VPC Settings	ID of the VPC you previously created. For example, vpc-0deecc96935b9ef73.
  Subnet Settings	Public subnet that belongs to the VPC.
  Security Group Settings	Create a new security group based on seller settings for the first HAProxy Enterprise instance, then select the same security group for other instances.
  Key Pair Settings	Create a new EC2 key pair, or select an existing one. Select the same key pair for all HAProxy Enterprise instances.

  In other fields, keep the default values or select other values that better suit your needs.

Create an AWS target group

A target group routes requests to one or more registered targets, such as HAProxy Enterprise instances, using the TCP protocol and the port number that you specify.

1. Open the Amazon EC2 console.

2. In the Load Balancing section on the left, select Target Groups.

   

3. Create a target group with the following characteristics, then click Next.

   Field	Value
   Target type	Instances
   Protocol	TCP
   VPC	The virtual private cloud (VPC) you created previously. For example, vpc-0deecc96935b9ef73.

   In the other fields, keep the default values or select other values that better suit your needs.

4. In the Register targets page, select the HAProxy Enterprise instances you created previously, then click Include as pending below.

   

5. Click Create target group.

Create an AWS Network Load Balancer

The AWS Network Load Balancer selects a target HAProxy Enterprise instance using a flow hash algorithm based on the source and destination IP addresses and ports, the protocol, and the TCP sequence number.

1. In the Load Balancing section on the left, select Load Balancers.

   

2. Create a Network Load Balancer with the following characteristics.

   

   Field	Value
   Scheme	Internet-facing
   VPC	The virtual private cloud (VPC) you created previously. For example, vpc-0deecc96935b9ef73.
   Mappings	Select your Availability Zone and the corresponding subnet.
   Listeners	Default (a listener that accepts TCP traffic on port 80).
   Default action	Select the target group you created previously.

   In the other fields, keep the default values or select other values that better suit your needs.

   

3. Click Create load balancer.

Test your setup

Once you have created a Network Load Balancer, wait a few minutes and check that the HAProxy Enterprise instances in your target group have passed the initial health check.

You can then test that the layer 4 AWS Network Load Balancer sends traffic to your layer 7 HAProxy Enterprise load balancers.

1. In the Load Balancing section on the left, select Target Groups.

   

2. Select the newly created target group, and check that your HAProxy Enterprise instances are ready.

   

3. In the Load Balancing section on the left, select Load Balancers.

   

4. Select the newly created load balancer.

5. Copy the DNS name of the load balancer and paste it into the address field of a web browser.

   For example, strawberry-f9f565c7eb5b3cd3.elb.eu-west-3.amazonaws.com.

   The browser displays the statistics page of your HAProxy Enterprise instance.

   

You can now:

• configure your backend server pool,

• edit the frontend section of your HAProxy configuration file (each AWS Network Load Balancer in the Availability Zone has a static IP),

• edit the backend section of your HAProxy configuration file,

• copy the configuration file to all HAProxy Enterprise instances in the AWS target group.
