Movies and TV shows, which constitute 29% of the content, are expected to grow at a CAGR of 15% over the next five years, driving the need for robust CDN infrastructures.‍‍Static Part The major bulk of data transfer in video streaming is static content. Given its unchanging nature, static content is ideal for caching.

‍Static Part The major bulk of data transfer in video streaming is static content. This type of traffic originates directly from the server, making it more challenging to handle due to latency and server load considerations; it’s hard but not impossible. It has its encoding, metadata, and, in specific cases, user profiles as well.Â
