You do not need a cloud load balancer to load balance. Ten lines of Nginx will spread traffic across a pool of servers, and understanding those ten lines teaches you what the managed services are quietly doing for you.

One Linux task, one AWS task. Turn Nginx into a load balancer in front of three app servers, then create an IAM user, group, and read-only policy. The tasks come from the KodeKloud Engineer platform.
Nginx load balancer: an upstream block and a proxy_pass
On the load balancer host, install Nginx and get it running:
yum install -y nginx
