A Content Delivery Network, or CDN, refers to a collection of servers distributed in different strategic geographical areas working together to provide internet content to your computer, tablet or another mobile device quickly.

With the increase in technology in today’s world, Content Delivery Network popularity has grown continuously. Most web traffic is currently being served through content delivery networks, including traffic from major sites such as Amazon, Netflix, and Facebook.

How does CDN work?

A Content Delivery Network consists of a network of servers linked together to deliver internet content faster, reliably and securely, with minimal costs.
CDN works by getting the content closer to the topographical location of the users. It does this through strategically located data centers known as Points of Presence (PoPs). The PoPs are positioned around the globe and within each PoP are hundreds and hundreds of caching servers. The PoPs and cache servers aid in improving connectivity and accelerating the content delivery speed to the end-user.

What are the advantages of Content Delivery Networks?

The benefits of using a Content Delivery Network can vary subject to your business, company size and needs. The primary benefits for the majority of CDN users can be broken down into four different components:

• Decreasing web page loading times

By offering closer website content distribution to web visitors through a nearby CDN server, users experience faster website loading times. Web users are generally motivated to use websites with a quick page load time. It’s very easy for users to bounce away from web pages with slow page loading times, adversely affecting their ranking on search engines. Therefore, using a content delivery network can lessen the users’ bounce rates and increase the amount of time they spend on the website. Having a website that loads pages faster will result in higher visitor traffic and longer page visits.

• Increased availability and redundancy

An increase in the amount of web traffic or a hardware failure can interfere with normal website functionality, resulting in downtime. Since CDNs are geographically distributed, they can handle increased web traffic and endure hardware failures better than many traditional servers. Suppose one or more CDN servers break down and go offline for various reasons? It’s no problem since the other functioning servers can quickly and easily pick up the website traffic and ensure uninterrupted service delivery.

• Decreasing the costs of bandwidth

Bandwidth consumption costs are significant expenses for business websites. Every time a server responds to a user request, it incurs a bandwidth cost. Through caching and other optimizations, Content Delivery Networks can decrease the amount of data an origin server must deliver, minimizing the hosting costs for website owners.

• Improving website security

The ability of the Content Delivery Servers to handle website traffic spikes makes it perfect for mitigating DDoS attacks. These attacks occur when mischievous actors overpower your applications by sending more requests than a single server can handle. When your origin server goes down due to the increased volume, the downtime can negatively affect the web page’s availability for its users. A Content Delivery Network acts as DDoS protection.

Who can use a Content Delivery Network?

In the present day, over half of all web traffic is being served by Content Delivery Networks. These figures continue to move on an upward trend.

Anyone who has a webpage or mobile applications that are likely to be requested by several visitors at a given time can significantly benefit from a Content Delivery Network. CDNs are particularly useful to big, multi-faceted websites with users spread worldwide and websites with a lot of dynamic content.

Furthermore, many websites have large-scale operations, therefore, making Content Delivery Networks a wise choice. Examples include the following businesses and organizations:

E-commerce: Content Delivery Networks assist e-commerce sites in delivering their content faster and more efficiently, even during heavy traffic times such as holidays.

Mobile applications: Content Delivery Networks deliver rich location-based content for mobile applications, decreasing load times and improving responsiveness.

Government: Bulky, content-heavy websites can deliver crucial information to residents much faster and efficiently by using a Content Delivery Network.

Finance: Content Delivery Networks offer banking institutions a fast, safe, and dependable infrastructure to deliver sensitive information to consumers and experts.

Technology: Content Delivery Networks assist technology websites in responding to thousands of requests from billions of website users without a reduction in performance.
