Usage:
-
Create the necessary directories and files as per the structure above.
-
Run the following commands in the terminal:
cd terraform-project/aws
terraform init
terraform apply
cd terraform-project/azure
terraform init
terraform apply
-
Follow the prompts to confirm the changes.
-
Once the deployment is complete, you'll have infrastructure deployed in both AWS and Azure, organized into modules for networking, computing, databases, storage, and security.
