Introduction
Content Delivery Networks (CDNs) are networks of globally distributed servers that deliver web content, media, and applications to users with minimal latency. They enhance website performance, reliability, and scalability while reducing the load on origin servers. In 2026, CDNs are critical for businesses with global audiences, streaming platforms, e-commerce websites, and SaaS applications. By caching content at edge locations closer to users, CDNs improve page load times, boost user experience, and increase conversions. Modern CDNs also provide security features such as DDoS protection, web application firewalls, and encryption. When evaluating CDNs, buyers should consider global coverage, integration capabilities, AI optimization, analytics, and compliance. Selecting the right CDN ensures fast, reliable, and secure content delivery for all users worldwide.
Real-world use cases include:
- Streaming video and live events to international audiences.
