modules

This folder holds project specific modules that are used once or many times. To enable this, all resources in the module must be uniquely named, so that multiple instances can exist at the same time to enable blue-green deployments.

providers

This folder holds the main code that includes terraform HCL files that defines the infrastructure at its highest level, all project specific details must be in variables.
