This research investigates how CDNs (Content Delivery Networks) can improve the digital experience, as consumers increasingly expect fast, efficient, and effortless access to online resources. CDNs play a crucial role in reducing latency, enhancing scalability, and optimizing delivery mechanisms, which is evident across various platforms and regions. The study focuses on key CDN concerns, such as foundational and modern CDN architectures, edge computing, hybrid CDNs, and multi-CDN strategies. It also explores performance-enhancing topics, including caching, load balancing, and the novel features of HTTP/3 and QUIC. Current trends, such as integrating CDNs with 5G networks, serverless architectures, and AI-driven traffic management, are examined to demonstrate how CDN technology is likely to evolve. The study also addresses challenges related to security, cost, and global regulations. Practical examples from the e-commerce, streaming, and gaming industries highlight how enhanced CDNs are transforming these sectors. The conclusions emphasize the need to evolve CDN strategies to meet growing user expectations and adapt to the rapidly changing digital landscape. Additionally, the research identifies future research opportunities, particularly in exploring the impact of QC, the enhancement of AI services, and the sustainability of CDN solutions. Overall, the study situates architectural design, performance strategies, and emerging trends to address gaps and create a more efficient and secure approach for improving digital experiences.
