Infrastructure as Code (IaC) has become essential for modern DevOps practices. Two popular tools—Terraform and AWS CloudFormation—help automate infrastructure deployment. But which one is right for your needs in 2025?
🔍 What is Terraform?
Terraform is an open-source IaC tool by HashiCorp that allows you to manage infrastructure across multiple cloud providers like AWS, Azure, and GCP.
Pros:
- Multi-cloud support
- Modular architecture
- Large community
- HashiCorp Configuration Language (HCL) is human-readable
Cons:
- State file management can be tricky
- No built-in rollback
🔍 What is AWS CloudFormation?
CloudFormation is AWS’s native IaC tool, tightly integrated with AWS services and using JSON/YAML for templates.
Pros:
- Deep AWS integration
- Managed rollback on failure
- Free to use
Cons:
- AWS-only
- Less flexible than Terraform
- Steeper learning curve for complex templates
✅ When to Use Terraform
- You’re using multi-cloud infrastructure
- You need reusable modules
- You prefer a strong open-source ecosystem
✅ When to Use CloudFormation
- You’re 100% AWS
- You want tight integration with AWS services
- You prefer AWS-native support and rollback
🧠 Quick Example: Terraform vs CloudFormation
Let’s say you want to launch an EC2 instance.
Terraform Snippet:
resource "aws_instance" "web" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
}
CloudFormation Snippet:
Resources:
EC2Instance:
Type: "AWS::EC2::Instance"
Properties:
InstanceType: "t2.micro"
ImageId: "ami-0c55b159cbfafe1f0"
Both do the job, but Terraform’s syntax is easier to read and reuse.

🔚 Conclusion
Both tools are powerful, but the right choice depends on your infrastructure goals. Use Terraform for multi-cloud flexibility. Stick with CloudFormation if you’re fully invested in AWS.
