In a nutshell, we discussed complete Terraform core workflows, which mainly consist of terraform init, terraform plan, terraform apply, terraform destroy, and the respective subcommands and their outputs.
In this chapter, we will discuss Terraform modules for Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP) cloud providers. From this chapter, you will learn how you can write modules and how you can publish and consume them. Learning about Terraform modules is important as this will help you to deploy large enterprise-scalable and repeatable...
