Load balancing is a key component to any application that’s highly available and scalable. In AWS, an Elastic Load Balancer distributes traffic across multiple instances, and even multiple availability zones if you choose. There are three kinds of load balancers in AWS: Application Load Balancer, Gateway Load Balancer and Network Load Balancer. This video will focus on Application Load Balancers.
In this hands-on tutorial, I’ll walk you through how set up two new Linux EC2 instances that are used as web servers. Then we’ll create an Application Load Balancer and a Target Group to balance traffic between the two instances.
