puppet test

Write a puppet master and slave application that does the following.

1: Ensures that all nodes in the system have the following config

a)Nginx is configured, running and has the following config in its home.conf file.

server_name home.somedomin.in 192.168.10.1;

# uWSGI serving Django.

upstream django-somedomin-home {

# Distribute requests to servers based on client IP. This keeps load

# balancing fair but consistent per-client. In this instance we're

# only using one uWGSI worker anyway.

ip_hash;

#server unix:///tmp/home-somedomin-uwsgi.sock;

server localhost:8005;

}

b) DNSMasq is running, it exists and has the following config 

address=/home.somedomin.in/192.168.10.1

c) Interfaces file exists, network manager is running and the following config is applied to all Client nodes

# /etc/network/interfaces

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

auto eth0

iface eth0 inet dhcp

# Example to keep MAC address between reboots

#hwaddress ether DE:AD:BE:EF:CA:FE

# WiFi Example

auto wlan0

iface wlan0 inet static

address 192.168.10.1

netmask 255.255.255.0

network 192.168.1.0

gateway 192.168.1.1

Once you are done with the application. Please push your code to github and share the github account with me. 

You will be rated on 

1: Code quality

2: Commenting and clarity of thought

3: using libraries to achieve your task.

Questions to answer - 

1: If you had to solve one problem in the world, what would that be.

2: If we had to deploy a 1 million nodes network server infrastructure, what do you for see as possible challenges, issues. How would you overcome each? What measures would you put in place to detect such issues before the customer? How would you ensure that somedomin product is running 100% of the time, both online on AWS and offline through the network servers.  

Draw out the possible architecture for such a solution and list down the technologies you will chose.
