• How do you convert hardcoded values into Terraform variables (region, instance type, bucket name)?

• How do you create variables.tf and terraform.tfvars?

• How do you re-run Terraform while ensuring idempotency (no unnecessary recreations)?

---

Lab 6: Create a Reusable Terraform Module

• How do you build a Terraform module that launches an EC2 instance?

• How do you parameterize the module with:

  • Name tag

  • Instance type

  • AMI

• How do you use this module to create three EC2 instances?

• How do you configure multiple AWS providers using alias?

• How do you deploy EC2 resources to two different regions (e.g., us-east-1 and us-west-2)?

• How do you output the public IP addresses of both instances?

• How do you validate the deployment by SSH’ing into instances in both regions?

---

Lab 10: Terraform Workspaces (Dev / Stage / Prod)

• How do you create Terraform workspaces: dev, stage, and prod?
