Recent high-profile cloud platform outages have underscored the importance of adopting a multi-CDN strategy to mitigate operational risks, enhance resilience, and optimize performance. By distributing traffic across multiple content delivery networks (CDNs), companies can maintain uptime and reduce the impact of regional bottlenecks or outages, ensuring a high-performance experience for users worldwide. Multi-CDN strategies can be implemented through various methods, including DNS-based steering, Layer 7 traffic management, CDN chaining, and client-side steering, each offering different levels of control and flexibility.
