Introduction to CDN’s
This course was originally produced in 2013 and last updated in 2016 (as described on the Training page). This WordPress post was published on 1 April 2016. The linked Prezi is titled as a 2018 presentation and includes audio commentary. That title year is not the same as the course’s 2013–2016 production dates. The March 2018 CDN tutorial embeds the same Prezi file; that post’s date is when the tutorial was published, not a second deck. Prices, provider comparisons, offload percentages and routing guidance in the Prezi are historical, not current advice. The Prezi itself has not been rewritten for 2026.
In this training video, I answer the most common Content Delivery Network questions such as;
What are CDN’s?
How does a CDN work?
Who uses a CDN?
How does a CDN make my website faster?
Who are the CDN players?
How much does a CDN cost?
