Little consumer education goes a long way. Here is a simple explainer why CDN is important. And why having media on relay is not scalable! πΆπΎπ«‘
Imagine a grocery store as a website, and the items in the store as the content on the website. People visit the store to get the items they need, just like they visit a website to access its content.
Now, let's say this grocery store (website) is very popular and has customers from all over the city (users from around the world). The problem is that the store is located in only one part of the city (the website's server is in one location), so people from far away have to travel long distances to get their items, which takes time and can be frustrating (slow website loading times for users far from the server).
This is where a CDN, or Content Delivery Network, comes into play. Think of a CDN as a chain of smaller grocery stores (proxy servers) spread out across the city (world). These smaller stores hold a selection of the most popular items from the main store (copies of the website's content). When customers from different parts of the city want to get their items, they can now go to the nearest smaller store (proxy server) instead of traveling to the main store. This way, they get their items faster and more efficiently (faster website loading times for users).
In summary, a CDN is like a network of smaller grocery stores that distribute the most popular items from the main store to various locations, making it faster and more convenient for customers to access those items, just as a CDN helps deliver a website's content more quickly to users around the world.
