Files:

Defining the resources for the network:

• resources.yaml
• resources-parameters.json

Defining the computational instances:

• servers_final.yaml
• servers-final-parameters.json

Running the code that build the cloud infrastructure

1. create the network and elements subnets, VPS, gateways, etc.

2. create the instances and the define the code for the installation inside the instances

bash create_stack.sh instances servers_final.yaml servers-final-parameters.json
