CDN Comparison: Amazon, Alibaba Cloud, IBM, Google Cloud, and Microsoft Azure

To learn more about CDN and its operations, keep reading.

CDNs, or content delivery networks, are a crucial component of every online company plan. Nowadays, the majority of consumer data is available online. The end consumer searches for speed while using the internet, whether it's for a straightforward Google search or to stream a film from Netflix or YouTube.

Suppose that even if your mobile device has a fast internet connection, the live video buffer on Amazon Prime or Netflix is too sluggish. What then guarantees that the user may view material from a game, app, or website at lightning-fast speed?

One may say, a CDN. Not entirely, but it certainly contributes significantly to making sure the information is supplied as soon as feasible.

What is CDN?

A content delivery network, or CDN, is a system of dispersed networks or servers that sends web pages, photos, videos, and other material to users based on their location, the content delivery server, and the hosting server. 

This indicates that the user's location, the location of the hosting server or the website, and the content delivery server's location are the three main variables involved when a content delivery network (CDN) works.

CDN Explained

Whenever a user queries a webpage via the internet, the CDN starts working. It routes the request to the delivery server nearest to the user from the server of the original site.  Cache pictures and other site material are stored by the CDN. In order to transfer any additional stuff that wasn't previously cached, it makes contact with the original server.

In this case, the user's request will be handled by the server that is nearest to them. For example, when a user from America tries to visit a website hosted in India, the request is routed through a local CDN server located in America rather than the server of the original website.

An average internet user expects a page to load in two seconds or less, according to findings from an Akamai survey, and they will leave a website after three seconds instead of waiting longer. The difficult issue of latency is resolved by CDNs, which essentially reduce the distance that exists between users and hosting servers. 

Even if there are many CDN providers available, it might be challenging for a newcomer to select the best match.

Key Features of Best CDN Providers

Comparisons: Google CDN Vs Amazon Cloud Front Vs IBM Cloud CDN Vs Alibaba Cloud CDN Vs Azure CDN

Alibaba Cloud CDN

Alibaba Cloud's CDN services include a distributed network that is built on top of the transport network. Additionally, it has edge node clusters dispersed throughout various locations. Reducing network congestion is achieved by offloading traffic from origin servers.

Fast content delivery networks like Amazon CloudFront are well-known for securely delivering files, movies, APIs, and apps to users at high transfer rates and minimal latency. Because CloudFront offers a developer-friendly environment, users may tailor its functionality to suit their own needs.

It serves as the entry point for any user application, thwarting assaults before they have a chance to reach the origin server. Application security is further ensured via HTTPS and SSL/TLS encryption. Because CloudFront provides access restrictions, the user has the ability to manage who may visit the website.

Key Features:

  • Because CloudFront and Amazon Web Services (AWS) are completely linked, CloudFront may operate with AWS's services, including Lambda@Edge, Amazon EC2, AWS Shield for DDoS mitigation, Amazon S3, and Elastic Load Balancing.
  • With a private committed price system and pay-as-you-go pricing that requires no up-front costs, users only have to pay for what they use.
  • Operates on AWS's worldwide network, which has over 410 PoPs (points of presence) and is equipped with sophisticated routing and automatic network mapping.
  • Customizable price options, combined requests, and free data transfer out of AWS regions allow users to save money.
  • For improved user speed, both static and dynamic material may be accessed thanks to TCP optimization.
  • Cloudflare delivers the complete website simply using one domain name. This quickens the process of uploading and downloading your website's content.
  • Uses layered caching and optimized de-duplication to reduce cache churn.
  • Uses AWS Web Application Firewall, Amazon CloudFront, AWS Shield, and Amazon Route 53 to defend against denial-of-service (DDoS) attacks on the network and application levels.

Azure CDN

With vast scalability and worldwide coverage, Microsoft Azure CDN provides safe and dependable content delivery. Users may start using it right away and grow it in a matter of minutes because of its close connectivity with Azure services. On a pay-as-you-go basis, Microsoft Azure CDN facilitates faster load times, lower bandwidth use, and increased performance for users.

For managing streaming video games, websites or apps, other types of media, IoT endpoints, etc., this CDN is the perfect choice. Additionally, Azure Front Door, a cutting-edge cloud CDN solution from Microsoft, has excellent speed, scalability, and security features. It combines cognitive threat prevention with CDN technology in an easy-to-deploy and administer package.

When it comes to CDN service, users may pick between Azure Front Door and Azure CDN. We have just discussed the characteristics of Azure CDN in this blog post comparing CDNs. You may go here for additional information about Azure Front Door.
