Developer Walks Through Full Terraform Lifecycle to Provision Azure Resources

A developer at Hagital Cloud Solutions completed a hands-on Terraform exercise to provision and tear down a single Azure Resource Group named hagital-rg. The workflow covered all key stages: writing configuration files, initializing the provider, formatting and validating code, previewing changes with a plan, applying the infrastructure, and finally destroying it. The exercise highlighted that each Terraform command serves a distinct purpose in catching errors before any real cloud changes are made. A key lesson was that not all errors originate in Terraform itself — authentication failures, for instance, often stem from Azure CLI or network issues. The walkthrough also underscored the importance of running terraform destroy after testing, as forgotten cloud resources can silently accumulate costs.
