What is Terraform?

Accepted Answer

**Terraform** — Infrastructure as Code (IaC).

```hcl
# main.tf
provider "aws" {
  region = "us-west-2"
}

resource "aws_instance" "web" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"

tags = {
    Name = "WebServer"
  }
}

resource "aws_s3_bucket" "data" {
  bucket = "my-data-bucket"
}

output "instance_ip" {
  value = aws_instance.web.public_ip
}
```

```bash
# Commands
terraform init
terraform plan
terraform apply
terraform destroy
terraform state list
terraform import aws_instance.web i-1234567890abcdef0
```
