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 data from the nearest edge location, reducing latency and improving performance.
As digital experiences become more complex and global, CDNs play a critical role in ensuring fast load times, high availability, and secure content delivery. They are also increasingly integrated with security features like DDoS protection, web application firewalls, and bot mitigation, making them essential infrastructure for modern applications.
Common Use Cases
- Website acceleration and performance optimization
- Video streaming and media delivery
- API and application delivery
- E-commerce performance and uptime
- Security protection (DDoS, bot filtering)
What Buyers Should Evaluate
- Global network coverage and edge locations
- Performance and latency optimization
- Caching and content optimization features
- Security capabilities (WAF, DDoS protection)
- Integration with cloud and DevOps tools
- Scalability and reliability
- Pricing model (usage-based, bandwidth-based)
- Ease of setup and management
- Analytics and reporting
Best for: Enterprises, SaaS platforms, e-commerce businesses, media companies, and any website with global users or high traffic.
Not ideal for: Small static websites with minimal traffic where basic hosting performance is sufficient.
