All that goes without saying that CDN is a less costly solution than other types of hosting. Since video requires a lot of storage space, some companies face the fact that one server may not be enough. Investing in infrastructure is very expensive, and takes month, if not years, for full integration. When the number of video files is growing, this mission becomes almost impossible. On the contrary, CDN provides automatic caching on all servers, and always turns out to be cheaper. Whenever you need it, you will be able to switch to a more powerful configuration.
