Making 4K video a reality poses challenges for content delivery due to the increased bandwidth requirements compared to 1080p video. Transitioning to 4K will require content to be distributed closer to the edge of networks through colocation facilities rather than relying solely on distribution from tier 1 markets, in order to avoid rising transmission costs and allow for sufficient scaling. Moving content distribution to colocation facilities at the edge can help reduce transmission costs by millions while improving performance and allowing further traffic growth.
