How do e-commerce sites use CDNs?

E-commerce sites use CDNs to accelerate product page loads, serve optimized product images across devices, handle traffic spikes during sales events, protect against DDoS attacks, reduce cart abandonment through faster checkout flows, and serve personalized content at the edge based on user location and behavior.

Why do streaming platforms need CDNs?

Streaming platforms rely on CDNs to deliver video content with minimal buffering by caching segments at edge servers near viewers. CDNs handle adaptive bitrate streaming, reduce origin bandwidth costs by 90%+, manage concurrent viewer spikes during live events, and ensure consistent quality across geographic regions.

How do gaming companies use CDNs?

Gaming companies use CDNs for distributing game updates and patches (often tens of GB), reducing multiplayer game latency through edge servers, serving in-game assets dynamically, protecting game servers from DDoS attacks, and delivering real-time leaderboards and matchmaking data through edge computing capabilities.

What role do CDNs play in SaaS applications?

CDNs improve SaaS application performance by caching static assets, API responses, and dynamic content at edge locations. They enable global deployment without multiple origin servers, provide WAF protection for web applications, handle SSL termination, and support real-time features through edge computing and WebSocket connections.

How do news and media sites benefit from CDNs?

News and media sites use CDNs to handle massive traffic spikes during breaking news, serve large volumes of images and video content efficiently, deliver geo-targeted content, optimize ad delivery performance, protect against DDoS attacks from viral content, and ensure availability during high-profile events.
