Solved: 3 CDN

Sure, here’s your requested article regarding 3 CDN – Cloudflare, Amazon CloudFront, and MaxCDN.

CDN (Content Delivery Network) is a widely used technology to provide faster web page load times and reduced network latency by storing copies of a website’s content in multiple geographically diverse locations. This guarantees users receive content from a location physically closest to them, hence enhancing the overall user experience.

Cloudflare is the most popular CDN service in today’s web world due to its broad range of services and advanced security features.

Cloudflare: Speed and Security Served Together

As an excellent CDN, Cloudflare does more than ensuring quick content delivery. The way it handles the DNS resolution, making it more challenging for a malicious entity to launch a DDoS attack, is remarkable. Suppose you’re a JavaScript developer hoping to incorporate Cloudflare into your workflow.

var cloudflare = require('cloudflare')({
  email: 'email', 
  key: 'apiKey'
});
  
var zoneId = "023e105f4ecef8ad9ca31a8372d0c353";
  
cloudflare.dnsRecords.browse(zoneId).then(function (resp) {
  console.log(resp.result);
});

The above snippet logs all DNS records of a specific zone. This is one fundamental way of using Cloudflare in a JavaScript environment.

Amazon CloudFront: A Robust Content Delivery Network

Amazon CloudFront, another brilliant CDN service, is a part of the Amazon Web Services (AWS) suite. It integrates with other AWS services smoothly, enabling developers to speed up content delivery with excellent configurability and security.

Suppose you want to implement CloudFront in your JavaScript code.

var AWS = require('aws-sdk');
AWS.config.update({accessKeyId: 'id', secretAccessKey: 'key'});
var cloudfront = new AWS.CloudFront();

//To create an invalidation
var params = {
  DistributionId: 'E3LDI50ES5F6', 
  InvalidationBatch: { 
    CallerReference: 'string',
    Paths: { 
      Quantity: 1, 
      Items: [
        '/path',
      ]
    }
  }
};

cloudfront.createInvalidation(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);          
});

The code creates invalidation for CloudFront CDN, effectively clearing the cache.

MaxCDN: Where Speed Meets Simplicity

MaxCDN is an affordable, easy-to-integrate solution that improves site speed remarkably.

Here’s an example of incorporating MaxCDN in a JavaScript project.

var MaxCDN = require('maxcdn');
  
var api = new MaxCDN('alias', 'consumer key', 'consumer secret');
  
api.get('zones/pull.json', function(err, res) {
  console.log(res.data.data);
});

In conclusion, CDN plays a vital role in modern day web technologies. Understanding and implementing it in your projects not only improves user experience but also provides an extra layer of security to your web application.
