  • 1. Content Delivery Networks and Joomla! Mike Carson
  • 2. What is a CDN?
    • A content delivery network or content distribution network ( CDN ) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, so as to avoid bottlenecks near that server.
    • Content types include web objects, downloadable objects (media files, software, documents), applications, real time media streams, and other components of internet delivery (DNS, routes, and database queries).
  • 3. Example of a CDN Network
  • 4. Why use a CDN?
    • Incorporating a CDN with your website provides you with several benefits, including the following:
    • Faster Page Loads - Since most of your files will be served from a much closer location to your end-users, the speed in which your page loads will be greatly increased.
    • Reduced Server Load - Since most of your files are no longer served by your own host, your server will be freed up to perform the basic tasks required of it.
    • Handle More Visitors - Because of the improvements just mentioned and other factors, your website will be able to handle the strain of a much larger user base that it could otherwise.
    • Higher SEO Rankings - Caused by the increase in performance to your site, something Google recently claimed effects SEO rankings.
  • 5. Who should use a CDN?
    • Anyone who:
    • Site owners that have limited server bandwidth.
    • People that find traditional CDN cloud hosting too expensive.
    • People that have slow or old servers.
    • People that need lower server load.
    • Owners of huge websites.
