The Café That Went Viral: A Simple Story About CDNs

Imagine you own a cozy café on a quiet street!

At first, business is good and functioning smooth, locals love the vibe. People nearby drop in and everyone gets their delicious coffee quickly. This makes you, your barista and your customer happy.

One day, your café goes viral in social media and suddenly people from all over the city, country and even from other countries want your coffee. But there is a catch! They all have to travel that same tiny, quiet street, and they have to travel hundreds, may be thousand of kilometers to buy your coffee. The line grows, the wait time explodes, and your barista is overwhelmed. Some customers leave before even placing an order. Customers get stress, Barista get stress and then you. Meantime you think of expanding the business by hiring new baristas and adding more space to reduce the waiting time, but still you cannot do this because you are located on a tine street.

One day you come up with a newer, better idea,

Instead of forcing everyone to come to your original café, you open branches in different neighbourhoods. These branches don't brew new secret recipes, they simply serve the same coffee you already perfected at the original shop. They keep a fresh supply ready so nearby customers can walk in, grab their favorite drink and leave happily in minutes. No more lines, no more waiting and most importantly no more stress.

Now think of your website!

The original café is your origin sever and the new branches you opened are CDN edge servers. Now, when someone need your coffee (website content), they go to the nearest branch, not the original café. They get the same coffee, but with less travel time and waiting time. Your original café still exists but it mostly deliver coffee beans and recipes to the branches when they run low or they make special request, instead of handling every single customer.

Since the branches takes over the heavy lifting, something interesting happens.

• Customers are happier because they het served quickly (less waiting/access time).

• Your original café is calmer and more reliable.

• You focus on improving your menu instead of just surviving the rush.

That is what a CDN does for your website. It transform your single, stressed origin into a network of nearby branches that cache your content. Therefor users around the world experience your webiste as if it were right next door.
