Multi-CDN Architecture: Enhancing content delivery resilience in high-traffic digital platforms

Shankar, Arun (2025) Multi-CDN Architecture: Enhancing content delivery resilience in high-traffic digital platforms. World Journal of Advanced Engineering Technology and Sciences, 15 (2). pp. 2084-2090. ISSN 2582-8266

This article details the architectural principles and implementation strategies of Multi-Content Delivery Network (Multi-CDN) systems for organizations facing global content distribution challenges. As digital platforms increasingly serve critical content to geographically dispersed audiences, the limitations of single-provider CDN solutions have become apparent, particularly during high-traffic events and regional outages. The core components of effective Multi-CDN architectures include provider selection criteria, intelligent traffic routing mechanisms, and failover protocols that enhance content availability across diverse network conditions. Performance optimization techniques through strategic cache distribution, regional performance mapping, and real-time analytics enable dynamic CDN selection. Implementation considerations vary across digital platform categories including streaming media, e-commerce, and gaming networks, each with unique content delivery requirements and user experience demands. This framework provides technical decision-makers with both theoretical understanding and practical guidance for designing robust content delivery infrastructure capable of maintaining performance and availability despite the unpredictable challenges of internet-scale distribution.
