CDN Integration & Edge Caching
Understand how Content Delivery Networks (CDNs) and edge caching improve content delivery speed globally.
What are Content Delivery Networks?
Imagine your website visitors are all over the world. If your server is in New York, someone in Tokyo will experience a slower load time due to geographical distance.
A Content Delivery Network (CDN) is a distributed network of servers (often called 'edge servers' or 'Points of Presence' - PoPs) that work together to deliver web content to users based on their geographic location.
Why CDNs are Essential for Speed
The main goal of a CDN is to reduce latency – the delay before data transfer begins following an instruction. By placing content closer to the user, CDNs drastically cut down the physical distance data has to travel.
- Faster Load Times: Users get content quicker.
- Improved User Experience: Happy users mean more engagement.
- Better SEO: Search engines favor faster websites.
