Technical Test

This task should demonstrate SRE skills, using all of the below:

• AWS services
• Infra as a Code(IAC) tools such as AWS Cloud Formation,Terraform etc.,
• End to End Automation
• Configuration Management (or) Scripting
• Source Control

If your solution provides a list of manual steps, you are doing it wrong.

Task

a) Launch 3 separate Linux nodes using the tools of your choice

2 x application nodes
1 x web node

b) Deploy the sample application to the appropriate nodes

c) Install NGINX on the web node and balance requests in a round-robin fashion

Goal

Sending a HTTP request to the web node should return the response:
Hi there, I'm served from <application node hostname>!

Demonstrate the round-robin mechanism is working correctly

Considerations

Share your work on a public git repo
Include a README.md with clear and concise instructions
Invocation should be simple and intuitive
Take care not to over engineer a solution

Sample application code (Golang)

package main

import (
	"fmt"
	"net/http"
	"os"
)

func handler(w http.ResponseWriter, r *http.Request) {
	h, _ := os.Hostname()
	fmt.Fprintf(w, "Hi there, I'm served from %s!", h)
}

func main() {
	http.HandleFunc("/", handler)
	http.ListenAndServe(":8484", nil)
}
