CDN 101: Why a Global Content Delivery Network Matters
Explore the benefits of using a CDN for your site’s speed, scalability, and security—and how Jet integrates it seamlessly.
What is a CDN?
A Content Delivery Network (CDN) is a system of distributed servers that deliver content to users based on their geographic location. Instead of every visitor connecting to a single central server, a CDN ensures that your website’s images, scripts, and other assets are loaded from the server closest to them. This leads to dramatically faster load times, especially for global audiences, and helps your site stay available even during high-traffic events.
Why does your site need a CDN?
Imagine launching a new product and suddenly seeing a massive spike in visitors from around the globe. Without a CDN, your single server can quickly become overloaded, causing slowdowns or even outages. With a CDN, traffic is automatically balanced across many servers, ensuring a smooth and fast experience for everyone. Plus, CDNs add layers of security and redundancy that protect your site from attacks and unexpected failures.
