A content delivery network (CDNs) is a simple add-on feature you can use along with any hosting account. Through a CDN, your site can be distributed worldwide. The end result is faster page loads for users. That both means that users are happier with your site’s performance and that search engines will give you higher rankings, since speed is considered an important usability consideration by Google and others.

CDNs create a more dynamic OC spirits by making your static content – images, videos, JavaScript, etc. – more readily available. Zones categorize different types of files on a content delivery network. There are a plethora of advantages to using CDNs, and understanding standard zone nomenclature can improve your efforts. Both are describing brief below.

7 CDN advantages

  1. Utilizing the power of additional domains – An Internet browser is typically incapable of downloading more than four files simultaneously from any one domain. A CDN doubles that number because it is not accessing the same domain.
  2. Caching benefits – Downloads do not need to be repeated. The file is stored on the CDN server for future use. This caching process means that different users don’t have to repeatedly re-access the server for content.
  3. Stronger capabilities – Even if you have a low-and hosting account, signing on to a CDN makes your site a powerhouse. The sheer size and scale of the network increases your reliability (uptime), minimizes latency globally, and delivers data packets more consistently.
  4. Wider distribution – The web connects people and businesses all around the world. However, the location of your hosting company’s servers will determine how many connections users must pass through on different continents. A CDN expedites this process, accessing servers near users.
  5. Choice of script versions – Rather than being stuck with one version of script, you can choose which JavaScript or CSS file version you want to use.
  6. Information on users – Services such as Google Analytics and Moz Analytics contain great data on how traffic is flowing to and within your site, but additional data is always helpful. A CDN will give you analytics data on your site that is especially helpful in the area of video content.
  7. Affordable performative leap – By spreading out the workload, a CDN allows you to improve the experience users have on your site without having to worry so much about bandwidth and other reliability considerations. This aspect keeps your hosting costs reasonable.

Typical CDN zones

Zones are essentially different configurations for distribution via a CDN. Different categories of files are fitted with each zone depending on which configuration makes most sense for that type of file. Here are four of the zones you will most likely see:

  • Push zone – This type of zone is built for unchanging content: large files that are set in stone (e-books, white papers, etc.). Once anything in this zone is uploaded and distributed throughout the network, it sits there infinitely. Everything remains the same unless you change the settings, pull the files, or get rid of the zone.
  • Pull zone – This zone is for typical daily content being uploaded to your site (images, JavaScript, etc). Rather than you pushing the content, this own grabs it from a predetermined location when the file is first accessed by a user. You also configure a timeframe after which the file is removed from any CDN servers. After that point, the next request checks your server for an updated version.
  • VOD zone – This type of zone is for the heavy stuff (static audio and video clips). It works in the same fashion as the push zone. Once you upload and distribute to the network, it is there forever. Nothing changes until you either reconfigure your settings or clear the zone from the CDN.
  • Live zone – As its name suggests, this zone is built for live streaming (webinar, Internet radio, etc.). You identify the source of the stream, and then that source points out to your audience via the domain you choose. Similar to all but the pull zone, no timeframe limits the stream. You must remove the zone to stop it.
