Microsoft Cloud Azure for Content Delivery Network

• Content Delivery Network is a solution for delivering high bandwidth content in Microsoft Cloud Azure

• It is updated and takes file-data away from a local desktop or portable PCs to state-of-the-art data centers in order for making them easily accessible and convertible for on-demand services over the networks

• It has evolved to improve the mechanisms of the traditional CDN model

• It is an umbrella term spanning different types of content delivery services: Video Streaming, Software Downloads & Mobile Content Acceleration

• It can also work to accelerate dynamic content, which cannot be cached, by leveraging various network and routing optimizations

  
  

Benefits

• CDN has better performance and improved user experience and when using applications in which multiple round trips are required to load content

• They have a large scaling system to better handle instantaneous high loads, such as the start of a product launch event

• It can distribute user requests and services of content directly from edge servers so that less traffic is sent to the origin server

  
  

Features

• Dynamic Site Acceleration

• CDN Caching Rules

• HTTPS Custom Domain Support

• Azure Diagnostics Logs

• File Compression

• Geo-Filtering

  
  

How It Works

• In this process, Alice users request a file by using a URL with a special domain name, such as <endpoint name>.azureedge.net

• This DNS route and endpoint hostname send the request to the best performing POP location

• If no edge servers in the POP have the file in their cache then POP requests the file from the origin server

• The origin server can be used as an Azure Web App, Azure Cloud Service, Azure Storage Account or any publicly accessible web server

• If the TTL for the file hasn't expired then the POP edge server returns the file directly from the cache system

• This process results in faster and more responsive user experience
