Centralized Workspace: It stores your Terraform configurations and state (the record of your infrastructure) in the cloud, so you don’t have to manage them yourself.
Team Collaboration: Multiple people can work together on the same infrastructure with features like access control and change history.
Automation: Automatically runs Terraform commands to plan and apply changes to your infrastructure.
Safety Features: Adds safeguards like approval workflows and locking to avoid accidental changes.

• Output Variables: These are used to extract information from your Terraform configurations after deployment.

Question 5

What are the different ways to declare variables in terraform ?

Answer 5

• Declaring Variables in a variables.tf or Similar File

• Local-exec: Runs commands on your local machine. Example: Triggering a script to notify a monitoring system.
• file : The file provisioner copies files or directories from the machine running Terraform to the newly created resource.
