A Content Delivery Network (CDN) lets you host your static assets across hundreds or even thousands of nodes around the world.
- Serving content will be faster as visitors receive moderately “local” assets and many of them may be cached already.
- Lower server load on your end (reduced bandwidth and better concurrency support).
- Additional features – most CDNs also incorporate web application firewalls, DDoS protection tools or other goodies that facilitate both performance and security.
Some vendors are more expensive than others. So it’s mostly an ROI conversation.
