Imagine that you work for the motor-vehicle department of a governmental organization. The department runs several public websites that allow drivers to register their vehicles and renew their driver's licenses online.The vehicle-registration website has been running on a single server and has suffered multiple outages because of server failures. This results in frustrated drivers trying to register their vehicles by month's end before their registrations expire.The department would like to improve resiliency by adding multiple web servers to its site and distributing the load across them. They would also like to centralize their site on a single load-balancing service to simplify the URLs for site visitors.You need an Azure subscription to complete the exercises.

On a whiteboard, design a three server web infrastructure that hosts the website www.foobar.com. Requirements: You must add: 2 servers 1 web server (Nginx) 1 application server 1 load-balancer (HAproxy) 1 set of application files (your code base) 1 database (MySQL) You must be able to explain some specifics about this infrastructure: For every additional element, why you are adding it What distribution algorithm your load balancer is configured with and how it works Is your load-balancer enabling an Active-Active or Active-Passive setup, explain the difference between both How a database Primary-Replica (Master-Slave) cluster works What is the difference between the Primary node and the Replica node in regard to the application You must be able to explain what the issues are with this infrastructure: Where are SPOF Security issues (no firewall, no HTTPS) No monitoring Please, remember that everything must be written in English to further your technical ability in a variety of settings.
