A CDN (Content Delivery Network) is a system of distributed servers placed in different geographic locations that work together to deliver internet content (like websites, videos, images, and files) faster and more reliably to users.
Why CDNs are important
- Speed: Reduces loading time (low latency).
- Reliability: If one server fails, another takes over.
- Scalability: Handles large traffic spikes easily.
- Security: Helps protect against attacks like DDoS.
- Bandwidth savings: Caches content so the origin server isn’t overloaded.
Popular CDN providers include:
- Cloudflare
- Akamai Technologies
- Amazon CloudFront
- Google Cloud CDN
CDNs store copies of static content (like images, CSS, videos). This is called caching, and it’s what allows quick delivery without contacting the origin server every time
