Terraform Production Structure (Dev / Staging / Prod) — Part 6
So far, you've learned:
- EC2 deployment
- Variables and outputs
- Modules
- Remote backend (S3 + DynamoDB)
Now it’s time to answer a critical question 👇
👉 How do real companies organize Terraform projects?
🎯 What You’ll Learn
- Multi-environment setup (dev / staging / prod)
- Professional Terraform folder structure
- How teams manage infrastructure at scale
❗ The Problem
Your current setup might look like this:
main.tf
variables.tf
outputs.tf
👉 Works for learning
👉 Breaks in production ❌
Why?
- No environment separation
- Hard to manage changes
- Risk of deploying to wrong environment
🏗️ Production Structure
Here’s how professionals structure Terraform:
terraform-project/
│
├── modules/
│ └── ec2/
│ ├── main.tf
│ ├── variables.tf
│ └── outputs.tf
│
├── environments/
│ ├── dev/
│ │ ├── main.tf
│ │ └── backend.tf
│ │
│ ├── staging/
│ │ ├── main.tf
│ │ └── backend.tf
│ │
│ └── prod/
│ ├── main.tf
│ └── backend.tf
🔹 Why This Structure?
1️⃣ Separation of Environments
Each environment is isolated:
- dev → testing
- staging → pre-production
- prod → live system
👉 Prevents mistakes like deploying test code to production.
2️⃣ Reuse with Modules
All environments use the same module:
module "ec2" {
source = "../../modules/ec2"
instance_type = "t2.micro"
}
👉 Consistent infrastructure across environments.
3️⃣ Independent State Files
Each environment has its own backend:
terraform {
backend "s3" {
bucket = "tf-state-bucket"
key = "dev/terraform.tfstate"
region = "ap-southeast-1"
}
}
👉 Dev and prod never conflict.
🔄 Workflow Example
Deploy to Dev
cd environments/dev
terraform init
terraform apply
Deploy to Production
cd environments/prod
terraform init
terraform apply
👉 Same code, different environment.
🧠 DevOps Insight
This structure enables:
- Safe deployments
- Team collaboration
- Scalable infrastructure
👉 This is how companies manage cloud at scale.
⚠️ Common Mistakes
❌ Single folder for all environments
❌ Sharing same state file
❌ Hardcoding values
🎯 What You Just Learned
- Multi-environment Terraform design
- Production folder structure
- Environment isolation best practices
💡 Final Thought
Infrastructure is not just code.
👉 It’s a system that must be safe, scalable, and predictable.
🚀 What’s Next?
Next, we’ll go deeper:
👉 Terraform workspaces vs environments
👉 When to use each approach
