Things You Must Know Before Using a CDN

In this context, one such practice is to use a Content Delivery Network (CDN) for the web application frontend. The need for a CDN is prominent for web applications that have users in multiple geographical locations.

Over the past few years, web applications have crossed many notable hurdles. One such achievement is the speed of loading these applications.

The challenge CDN solves, is the limit with Speed of Light.

In this article, I will be discussing the need for using a CDN, and different strategies you can use to set it up in your architecture, and the common pitfalls you should avoid.

The Need for CDN

In your professional life, you might have experienced different latencies when viewing web applications from different parts of the world. When the webserver distance is far away from you, it’s likely to take more time to load the web application to your browser.

What is the reason for this delay? You are very much aware that when it comes to the frontend part of a web application, it requires loading the HTML, JavaScript, CSS, and Images to the browser at first for it to function. This shows the need for accelerating the speed of loading such assets.

The only way to improve the speed of loading these assets is to bring the frontend content closer to the user. However, moving the server is not always possible. This is where the use of CDN comes in to play. We can use a CDN to cache the frontend content closer to the user so that the latency of loading the frontend becomes less.
