Introduction
Content Delivery Networks (CDNs) are distributed networks of servers that deliver web content—such as images, videos, scripts, and APIs—to users based on their geographic location. Instead of loading content from a single origin server, CDNs cache and serve content from edge locations closer to users, significantly improving speed, reliability, and performance.
In today’s digital landscape, where user experience directly impacts engagement and revenue, CDNs are essential for ensuring fast load times, high availability, and secure content delivery across the globe.
Common use cases include:
- Accelerating website and web app performance
- Delivering video streaming and media content
- Protecting websites from DDoS attacks
- Scaling traffic during peak demand
- Optimizing eCommerce and SaaS platforms
What buyers should evaluate:
- Global edge network coverage
- Caching and cache invalidation capabilities
- Performance (latency, throughput)
- Security features (DDoS protection, WAF, TLS)
- Integration with cloud providers and platforms
- Developer tools and APIs
- Pricing model (usage-based vs flat-rate)
- Analytics and monitoring
- Support for dynamic and static content
Best for: eCommerce businesses, SaaS platforms, media companies, enterprises, and any website with global users.
Not ideal for: Very small websites with minimal traffic or local-only audiences.
