The templates have been separated into a network infrastructure template and a server infrastructure template. It was easier to do it this way and makes more sense rather than putting everything in a large single file and trying to determine the order of resource creation with DependsOn

network-infra.yml creates the logical network for the project. This stack should be run first.

server-infra.yml creates the server resources -- i.e the load balancer, security groups etc. This should only be run after the network-infra stack has been successfully created.

The shell scripts are a simple wrapper for the aws cloudformation command. They can be used by simply running the scripts and providing two parameters: Name of the stack to create and the file that contains the template

For example: ./create.sh ThirdSemesterLogicalNetworkStack network-infra.yml

1. Create the network infrastructure by running the network-infra stack.
2. Wait until this stack creation is completed on AWS
3. Create the server infrastructure by running the server-infra stack to complete the project.
4. To make things slightly easier, one of the outputs of the server-infra stack is the DNS name of the load balancer. Simply copy that out and open in a new tab. Alternatively, go to the load balancer on the console and copy out the domain name from there

N.B. There was no need to use ansible or any other provisioning tool since every requirement of the project could be completed using UserData
