Terraform - Infrastructure as Code

Terraform is an open-source infrastructure-as-code (IaC) tool developed by HashiCorp. It allows you to define and manage your infrastructure—servers, networks, databases, and more—as code. This enables you to treat your infrastructure with the same version control and automation practices as your application code. Using Terraform, you can consistently and reliably create, modify, and destroy your infrastructure, significantly reducing manual effort and the risk of errors.

Terraform utilizes a declarative approach. You describe the desired state of your infrastructure, and Terraform automatically handles the necessary steps to achieve that state. It supports multiple providers, including AWS, Azure, Google Cloud Platform, and others, enabling you to manage infrastructure across various cloud platforms.

Example Terraform Configuration

                
                    terraform {
                        required_providers {
                            aws = {
                                source  = "hashicorp/aws"
                                version = "~> 4.0"
                            }
                        }
                    }

                    # Configure the AWS Provider
                    provider "aws" {
                        region = "us-east-1"
                    }

                    # Create an AWS S3 Bucket
                    resource "aws_s3_bucket" "example" {
                        bucket = "my-terraform-bucket-${random_id.bucket_name.result}"
                        acl    = "private"
                    }

                    resource "random_id" "bucket_name" {
                        name = "bucket_name"
                    }

This example demonstrates a basic Terraform configuration to create an S3 bucket in AWS. It showcases the core structure including the provider configuration and a resource definition.
