A video CDN is a CDN that is specifically built to provide video streams. A CDN for streaming video allows a stream to reach viewers all over the world, reduces latency and buffering time, and assures that the stream’s source or origin server is not overburdened.
Reasons to use a CDN for Video
- Latency is reduced by reducing the distance between viewers.
- Streaming video follows the same technique as stated previously. The video material will load and play faster the closer it is to the viewer. A CDN’s server is likely to be closer to any given viewer than the stream’s origin.
- The origin server isn’t overloaded.
- Using a CDN’s numerous servers ensures that the server from which the stream originates is not overburdened with requests for the stream. A cluster of 200 servers is significantly more capable of broadcasting video to thousands of viewers than a single server.
- The bandwidth used by streaming content does not exceed that of the network.
- Only a specific quantity of data may move via a network at any given time. The term “bandwidth” refers to the maximum amount. When the volume of data travelling through a network exceeds the bandwidth, data delivery slows dramatically, similar to how limiting cars to one lane on a highway affects traffic. When a stream is supplied from a CDN’s various scattered servers, it is less likely that any single network will become overburdened.
