Simple HTTP Load Balancer

Technologies used:

1. HAProxy
2. Node.JS application servers

Commands to run

port=4444 nodemon appserver.js
port=5555 nodemon appserver.js
port=6666 nodemon appserver.js
port=7777 nodemon appserver.js
port=8888 nodemon appserver.js
haproxy -f http.cfg

Hit localhost:8080 on browser

(Add as many ports to http.cfg as desired to create more app servers to be load balanced.)

That's all it takes to create a Layer 7 Load Balancer!
