How a CDN works?

A CDN stores a cached version of the content in several PoPs or points of presence or also can be defined as geographical locations. This helps in reducing and minimizing the distance between your website server and visitors.

Each of those PoPs can contain a specific number of caching servers, which help in delivering content to the visitors located within its proximity.

A CDN puts the content in multiple areas at the same time and hence, can offer superior coverage to the users. This is how a CDN works; hence, your visitors can enjoy good speed in viewing their content.

What can a CDN do for you?

The CDNs of recent times can easily manage and handle a large number of IT-related tasks, and hence, help you to:

  1. Handle loads of high traffic.
  2. Improve the speed of page loading.
  3. Localize coverage without a huge expense.
  4. Block scrapers, spammers, and other unwanted and harmful bots.
  5. Load balance between several servers.
  6. Decrease bandwidth consumption.
  7. Secure the application.
  8. Protect the website from the attacks of DDoS, etc.

Who usually uses a CDN?

Nowadays, almost everyone uses CDN solutions. However, the number of CDN users is increasing with every passing year. Whenever you need to work online for your business, you will need the help of CDN more or less. It is more useful for some people as it offers some services free of charge.

However, the CDN is not for everyone to use. If you are running a website that is strictly localized, along with many users situated in the same area, using a CDN can offer you very little benefit.

Specifically, if a strictly localized website is running by you, and a lot of your users are located in the same area as your hosting, using a CDN can offer you little benefit.

However, numerous websites that operate on a large-scale use CDN for their tasks. CDN is a popular choice in the sectors like:

  • Online gaming
  • Mobile
  • Entertainment and Media
  • Advertising
  • Government
  • Higher education
  • Healthcare
  • E-commerce
