A multi-CDN strategy improves video platform resilience, performance, and user experience by distributing traffic across multiple content delivery networks. Unlike relying on a single CDN, this approach mitigates outages, micro-failures, and regional slowdowns through dynamic traffic routing. The paper outlines key implementation steps: workflow continuity, traffic policies, performance telemetry, and DNS or client-side traffic management. While requiring careful planning, it results in faster delivery, higher availability, cost savings, and competitive differentiation. Lumen emphasizes combining data-driven tools and best practices for successful execution.
