What is Content Delivery Network (CDN)?
It is a group of servers distributed geographically that stores content closer to the end user. Content Delivery Network allows you to transfer assets quickly that are needed for loading Internet content, HTML pages, JavaScript files, images and videos. Its popularity has been growing continuously and now day’s major web traffic is mainly served through CDN.
What Are The Benefits of Content Delivery Network?
- Improves Loading Time Of Website: By using nearby Content Delivery Network servers to deliver content to your website visitors (among other optimizations), your visitors will experience faster page load times. Visitors tend to click away from slow-loading sites, so using a Content Delivery Network will reduce bounce rates and increase time spent on your site. In other words, the faster your website is, the more visitors will stay and the longer they will stay.
- Reduces Bandwidth Cost: Web hosting bandwidth usage cost is a major expense for websites. The amount of data that origin servers must deliver can be decreased by Content Delivery Network through caching and other optimizations, resulting in lower hosting costs for website owners.
- Increases Availability Of Content Redundancy: Heavy traffic or hardware failures can disrupt the normal operation of the website. Because Content Delivery Network are distributed, they can handle more traffic than many origin servers and are more tolerant of hardware failures.
- Efficient: It helps in reducing the loading time of a webpage and bounce rate.
- Security: These services include distributed denial of service (DDoS) attack mitigation, web application firewall (WAF), and bot mitigation.
- Optimization: Content Delivery Network provides a variety of performances and services of optimization of content of the web that completes the stored content of the site.

How Does Content Delivery Network Work?
A Content Delivery Network primary function is the speedy, inexpensive, dependable, and secure delivery of material across a network of connected servers. CDNs set up servers at network exchange points to increase connection and speed.
These Internet Exchange Points (IXP) are the primary locations where different ISPs connect to each other to access traffic coming from different networks. CDN providers can reduce the cost and time of data transfer at high speed by connecting to these high-speed, interconnected locations. A CDN not only places the server inside the IXP but also performs many optimizations on standard client/server data transfers. CDNs are designed with data centers in strategic locations around the world, with increased security and to withstand all types of failures and Internet congestion.
How Does A CDN Improve Website Load Times?
When it comes to websites loading content, users quickly leave when the site slows down. CDN services can help reduce load times in the following ways:
- The globally distributed nature of a Content Delivery Network means reducing the distance between users and website resources. A CDN enables users to connect to a data center that is physically closer to them than the place where the site’s source server may be located. Faster service equates to shorter travel distances.
- Data can be sent to users more quickly with the use of hardware and software optimizations such as effective load balancing and solid-state devices.
- A Content Delivery Network can reduce the amount of data transferred by reducing the file size using techniques such as file minification and compression. Smaller file sizes mean faster load times.
- CDNs can also speed up sites that use TLS/SSL certificates by optimizing connection reuse and allowing TLS mocks.
What Is A CDN Host?
Rather than hosting the web and delivering content to consumers over the last mile, CDNs have geographically distributed content delivery network servers that deliver content close to users and their ISPs anywhere in the world. This temporary storage of content at the edge of the network reduces latency and allows the same content to be distributed to multiple users for more efficient access.
For network operators (also known as wireless service providers or mobile network carriers) struggling to keep up with the never-ending demand for online video, a Content Delivery Network hosting platform can be a very effective way to stay afloat in competition and an affordable solution. Content delivery networks enable network operators to deliver fast, secure, and reliable online experiences with the consistent quality expected from web-enabled devices.
Why Do You Need A CDN?
CDNs form the invisible backbone of the Internet, delivering online content at speed and scale to shopping, banking, healthcare, and other businesses. Without a Content Delivery Network that can replicate and store data from your main servers and deliver digital content wherever your users go on the web, internet speeds will slow down significantly.
You might not realize it, but if you’ve done almost everything online, CDNs have probably helped provide a fast, reliable, and consistent experience. Here’s a simple example of how the Content Delivery Network handles traffic in the background to achieve this. A CDN balances overall traffic and provides the best possible web experience for everyone accessing internet content. Think of it like traffic in the real world. There may be a route that is usually the fastest from point A to B if there are no other cars on it. But if it starts to get congested, it will be better for everyone if the traffic is spread over several different routes.
This means you’ll be sent on routes that are a few minutes (or microseconds at internet speed) longer, but you won’t be stuck in the traffic that usually occurs on the fastest routes. It can also mean that other cars are sent on a longer route and therefore sent on the fastest normal route without getting stuck in traffic. Therefore, it is important to load balance and make the best use of all available resources instead of throttling.
