Do you need dynamic site acceleration and a high-performance network? There is no alternative to employing Content Delivery Networks (CDNs), your ultimate solution to optimise content delivery. 

Powering your site with a quality CDN helps it thrive on the internet, lets your end-users enjoy seamless web browsing, ensures higher ranking on search engines, reduces bandwidth costs, and more!

Picking the most competent service can seem intimidating, especially when you have so many choices. To help you select the best one, I have come up with a list of the top 10 CDN.

What is a CDN

A Content delivery network or CDN is a group of geographically spread servers and data centers. Over an access request for website content, a CDN collects the original file from the origin server and the proxy servers cache and store it to deliver the content to the requested user from the closest server. 

A CDN speeds up delivery:

  • texts, scripts, graphics (web object)
  • Software documents, media files (downloadable object)
  • On-demand video streaming
  • Live video streaming
  • Social networks, etc.

A CDN can:

  • Improve your website uptime 
  • Limit latency 
  • Ensure speedy loading
  • Defend cyber threats and DDoS with SSL, TLS encryption, WAF (Web Applications Firewall), etc.
