Elastic Load Balancing allows the distribution of incoming traffic to your Amazon AWS infrastructure across multiple instances. This represents a great tool in avoiding failures in your applications and web traffic. ELB automatically detects fails in your EC2 instances and redirects traffic to other available instances. During this Lab, you will learn to create and use your first ELB instance to balance the HTTP traffic between two EC2 instances. You will also gain valuable understanding of the Classic Load Balancer behavior during an instance outage.



This is a beginner level Lab, however, in order to follow the next steps you should be able to:

  • Describe and launch EC2 instances
  • Describe and create a VPC
  • Describe, create, and configure Security Groups


Learning Objectives:

By the end of this Lab, you should be able to:

  • Create and configure a Classic Load Balancer
  • Add existing EC2 instances and a Classic Load Balancer
  • Restrict direct access to EC2 instances using Security Groups
