Content Delivery Network (CDN)
What is a CDN?
A Content Delivery Network (CDN) is a globally distributed network of servers that delivers web content to users based on their geographic location. CDNs cache static content like images, CSS, and JavaScript files on edge servers around the world, reducing latency and improving load times dramatically.
- Distributed server network across the globe
- Caches static assets closer to users
- Reduces server load and bandwidth costs
- Improves security against DDoS attacks
Why CDN is Crucial for Performance
Website speed directly impacts user experience, SEO rankings, and conversion rates. A 1-second delay in page load can reduce conversions by 7%. CDNs ensure your content loads fast regardless of where your visitors are located.
2x to 10x faster website loading speeds
Improved SEO rankings (speed is a ranking factor)
Better user experience and lower bounce rates
Enhanced security with DDoS protection
Reduced hosting costs through caching
