Day 7: Understanding Terraform State - Part 2

Welcome to Day 7 of the Terraform 30-Day Challenge! Today was all about deepening our understanding of Terraform state isolation. I explored different methods to manage and separate Terraform states for multi-environment setups. Here’s what I covered:

Reading Highlights

• State File Isolation: Why isolating state is critical for stability and predictability.
• Isolation via Workspaces: Using terraform workspace to create separate logical environments.
• Isolation via File Layouts: Organizing infrastructure using folder structures like /dev, /staging, and /prod.
• The Remote State Source: How to share state using backends like S3 and use terraform_remote_state data sources.

Hands-on Labs

• Lab 08: State Management
• Lab 09: State Locking

Activity: Practice Time

I practiced isolating Terraform state in two ways:

• Workspaces: Used terraform workspace new dev and similar commands to create environments.
• File Layouts: Created separate directories for each environment with its own main.tf and backend config.

Bonus Project

I set up remote state storage with AWS S3 and enabled state locking using DynamoDB. This ensures consistency and prevents accidental overwrites in team environments. I also simulated concurrent state changes to observe how locks prevent conflicts.
