Additional IaC Case Studies

Case Study 1: AWS CloudFormation

AWS CloudFormation allows developers to use a template to define and provision AWS infrastructure as code. This helps automate the setup of resources.

Note: CloudFormation templates can be written in JSON or YAML format.

Sample CloudFormation Template


{
    "AWSTemplateFormatVersion": "2010-09-09",
    "Resources": {
        "MyBucket": {
            "Type": "AWS::S3::Bucket",
            "Properties": {
                "BucketName": "my-example-bucket"
            }
        }
    }
}

Case Study 2: Terraform

Terraform is a popular open-source tool for building, changing, and versioning infrastructure safely and efficiently.

Sample Terraform Configuration


provider "aws" {
  region = "us-west-2"
}

resource "aws_s3_bucket" "my_bucket" {
  bucket = "my-example-bucket"
}

Case Study 3: Azure Resource Manager

Azure Resource Manager (ARM) enables users to manage their Azure resources through declarative templates.

Sample ARM Template


{
    "$schema": "http://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "resources": [
        {
            "type": "Microsoft.Storage/storageAccounts",
            "apiVersion": "2019-06-01",
            "name": "mystorageaccount",
            "location": "East US",
            "sku": {
                "name": "Standard_LRS"
            },
            "kind": "StorageV2"
        }
    ]
}

Best Practices

Use version control for your IaC templates.
Keep templates modular and reusable.
Test templates in a staging environment before production.
Document your infrastructure and templates clearly.

FAQ

What is Infrastructure as Code (IaC)?

IaC is a practice that allows you to manage and provision your infrastructure using code, enabling automation and improving consistency.

Why use IaC?

IaC provides benefits such as version control, ease of replication, error reduction, and faster deployments.

What tools are commonly used for IaC?

Popular IaC tools include AWS CloudFormation, Terraform, Azure Resource Manager, and Ansible.
