How does a CDN work?

A CDN (content delivery network or content distribution network) is a network of proxy servers that are linked together to deliver internet content. In order to improve connectivity and speed, a CDN places servers at the different networks’ internet exchange points (IXPs). IXPs are where various internet providers connect, allowing each other access to traffic from different networks. By connecting to these high-speed, highly interconnected locations, CDN providers are able to reduce both costs and transit time of content delivery.

In addition to placing servers in IXPs, CDNs also optimize client/server data transfers by placing data centers strategically around the globe and enhancing security. They then store a cached version of the content at multiple points of presence (PoPs) so that when content needs to be accessed, it can be accessed from the closest PoP rather than traveling a long distance to reach the user.

CDNs are designed to survive all kinds of internet congestion and failures.

Is a CDN the same as a web host?

CDNs (content delivery networks) do not host content and are not a replacement for a proper web host. That being said, CDNs do help to cache content at the network edge, improving overall website performance. Many websites opt for CDNs because they find that their performance needs are not being met by traditional web hosting services. CDNs are a good choice because they utilize caching to reduce hosting bandwidth, help prevent interruptions in service, and can also improve security.

Why use a CDN?

Using a CDN (content delivery network) improves your users’ experience by delivering content to them faster. It also makes the experience for all users by ensuring that servers are geographically distributed and content does not have to travel from a location that is remote to some users. This allows your website to load faster and reduces latency.

By distributing bandwidth across multiple servers, CDNs also help to prevent site crashes in the case of a traffic surge.

A CDN is a crucial part of the optimization strategy for any mission-critical website, especially those with heavy traffic.

Who uses CDN?

More than half of all internet traffic is served by CDNs (content delivery networks) and those numbers are on the rise. Pretty much everyone uses CDns.

CDNs are particularly popular on websites that operate on a larger scale, including in the sectors of:

• E-commerce

• Advertising

• Media and entertainment

• Mobile

• Healthcare

• Government

• Higher Education

• Online gaming

The only time it might not make sense to use a CDN is if you run a localized website, the users of which are all located in the same region as your host. In this instance, a CDN could actually worsen your website’s performance by introducing unessential connection point between users and a server that is already nearby.

What are the benefits of a CDN?

The benefits of using a CDN (content delivery network) include:

  1. Improvement of website load times - Pages load faster, which reduces bounce rates and increases the amount of time users spend on the site.
  2. Reduction of bandwidth costs - Bandwidth consumption costs for website hosting is a primary expense for websites. Through caching and other optimizations,Through optimization such as caching, CDNs reduce the amount of data that must be provided by an origin server. Less bandwidth consumption means less expense.
  3. Increased content availability - CDNs handle more traffic and can better withstand hardware failure thanks to their distributed nature.
  4. Improvement of website security - CDNs can improve security by providing optimizations such as DDoS mitigation and improvements to security certificates.
