CDN Setup

Overview

This project provisions a basic CDN setup using CloudFront to deliver static content globally with low latency. It connects a storage origin and configures caching and HTTPS for faster and secure delivery.

The goal is to enable high performance, global access, and simple edge caching.

Stack

• Terraform

• Amazon CloudFront

• Amazon S3

Architecture

User → CloudFront → S3 (Origin)

Step 1: S3 Bucket (Origin)

resource "aws_s3_bucket" "static" {
  bucket = "my-static-site-bucket"
}

Step 2: CloudFront Distribution

resource "aws_cloudfront_distribution" "cdn" {
  origin {
    domain_name = aws_s3_bucket.static.bucket_regional_domain_name
    origin_id   = "s3-origin"
  }

  enabled = true

  default_cache_behavior {
    target_origin_id       = "s3-origin"
    viewer_protocol_policy = "redirect-to-https"

    allowed_methods = ["GET", "HEAD"]
    cached_methods  = ["GET", "HEAD"]

    forwarded_values {
      query_string = false
      cookies {
        forward = "none"
      }
    }
  }

  viewer_certificate {
    cloudfront_default_certificate = true
  }
}

Commands

terraform init
terraform apply

Result

• Static content served via CDN
  

• Reduced latency using edge locations
  

• HTTPS enabled by default
  

• Cached responses for faster load times
  

Key Points

• Improves global performance
  

• Reduces load on origin (S3)
  

• Simple and scalable setup
  

• Works well for static sites
  

Final Note

This project demonstrates how to set up a basic CDN using CloudFront.

It ensures faster content delivery and better user experience with minimal infrastructure.
