You host your video on a Vietnamese server and everything runs smoothly. But when viewers in Singapore, Japan, or the US watch, the video buffers constantly. The reason: data has to travel from the Vietnamese server to the viewer — the physical distance creates high latency.
A CDN (Content Delivery Network) with GeoIP routing solves this by distributing copies of your video to multiple data centres around the world, automatically serving each viewer from the data centre closest to them.
How CDN GeoIP routing works
- You upload your video to a CDN provider
- The CDN automatically distributes the file to edge servers globally (or in the regions you select)
- When a viewer requests the video, the GeoIP system determines their location
- The video is served from the nearest edge server → lower latency, faster loading
When do creators need a CDN?
- You have a meaningful international audience (more than 20% of views from outside your home country)
- Your video is self-hosted (you are not relying on YouTube or TikTok as your CDN)
- You sell online courses with self-hosted video
- You have a website or app with embedded video
If you only post to YouTube, TikTok, or Facebook: These platforms already have their own global CDNs. You do not need to worry about CDN for that content.
Popular CDN options for creators
- Cloudflare Stream: Reasonably priced, built-in video features, wide edge network. Good for creators hosting video on their own website.
- Bunny.net Stream: Low cost, solid Asia Pacific coverage. Popular with online course creators.
- AWS CloudFront + S3: More flexible but requires technical setup. Suited to creators with a developer or an existing AWS stack.
- Vimeo Pro/Business: Vimeo already includes a CDN — a turnkey solution if you want something ready-to-use with no configuration.
Cost considerations
CDNs charge based on bandwidth (GB transferred). Before choosing a CDN, estimate your monthly views × average video file size × bandwidth ratio to calculate realistic costs. Also see: optimising video CDN costs for creators.
