Objectives

Configuring an Amazon ALB is a multistage process. We’ve broken it down into multiple tasks so that it’s easy to follow.

  1. Create Target Group

    Begin by creating one target group for the http protocol. You’ll add your Linux nodes to this group.

  2. Register Targets

    Add your Linux nodes to the target group.

  3. Create Your ALB

    Use Amazon’s Wizard to create an Application Load Balancer. As part of this process, you’ll add the target groups you created in 1. Create Target Groups.

Create Target Group

Your first ALB configuration step is to create one target group for HTTP.

Log into the Amazon AWS Console to get started.

The document below will guide you through this process. Use the data in the tables below to complete the procedure.
