This is an IaC/CaC example for an web application stack (based on linux server) including an loadbalancer, deployed using Terraform and Ansible.
What does it do This App shows how to deploy multiple IaaS ressources (in this case on Azure) with Terraform and configure the server services with ansible.
Why would you do this Instead of manually clicking, editing and adding all the needed ressources e.g. instances, loadbalancers, storages etc. you can automatically create, scale and configure them by using YAML-files.
Terraform provides the infrastructure, while ansible takes care of the linux server configuration.
