Design a content delivery network (CDN) for a global video streaming service. The CDN should efficiently distribute video content to users worldwide while minimizing latency and maximizing performance. Consider factors such as geographic distribution, caching strategies, load balancing, fault tolerance, and security in your design. Discuss how you would handle edge caching, content replication, and dynamic content delivery. Additionally, address how you would optimize the CDN for different types of devices and network conditions. Provide insights into the technologies, protocols, and architectural principles you would utilize to build and manage this CDN effectively
