How CDN Helps to Reduce Costs


A content delivery network (CDN) makes data transfer less intensive yet more effective. The conventional website model employs a single server for data storage; however, a CDN uses an entire system of powerful servers worldwide. The principal purpose of a CDN is storing copies of website files, granting a more stable, secure, and faster performance. 

Suppose a user is on a website without a CDN; the content must travel from the origin server, which can be long. Each user generates new HTTP requests, intensifying data transfer and boosting operating costs – but utilizing a CDN caches most of the website’s content in the network. So, when data exchange with the origin server decreases, bandwidth costs do, too. In basic terms, that’s one way a CDN reduces costs. 

Still, there’s much more to expand on, from security, site speed, and conversions to shutdown prevention and website growth and scalability – all of which, in turn, dramatically impact costs.

Boost Website Speed and Improve Conversions

A distribution network reduces the distance between the content and the user by processing every request with the closest node. As well as slashing the distance, a CDN cuts the number of steps and relays, which boosts a website’s speed – particularly image loading times. 

Website users expect sites and images to load immediately – and if they’re high-quality, this can take time. If it’s too long, a user may click off a website and go elsewhere, even with a couple of seconds delay, thus increasing bounce rates and lowering conversions – and sales. Not only do conversions suffer, but site speed and bounce rates are SEO metrics, which search engines punish websites for if they’re deemed poor. 

However, a CDN makes websites load faster using the closest server and optimizing images simultaneously, reducing this issue and, in turn, the cost per customer acquisition. A CDN file uploader is particularly useful for site owners with image-rich retail websites, such as online stores and e-commerce outlets. They can focus on image optimization and delivery of content across vast numbers of users viewing it on multiple devices.

Bandwidth Costs

Additionally, a CDN with strategic access to key Points of Presence (POPs) near the internet’s major peering points fine-tunes bandwidth efficiency and boosts the delivery of media-laden content, offering observable performance advantages to customers. As efficiency improves, bandwidth costs continue to go down.


60% of small companies subject to a cyber attack are out of business within six months. This sobering statistic means any business dealing with sensitive data must prioritize cyber defense, lest they risk losing significant sums, not to mention hanging up the ‘out of business’ sign. 

Naturally, protecting a single server is challenging; however, a CDN’s structure is more secure, thanks to its decentralized function. Furthermore, some CDNs can absorb and assess abnormal traffic spikes. If the CDN recognizes this anomaly and brands it acceptable – perhaps received from marketing promotions, for instance – it will serve that traffic. 

If not, it might consider the spike inappropriate and send it to a black hole full of scrubbing nodes. Because of this, a CDN can help protect a website from a DDoS attack before any dangerous damage occurs – damage that could’ve been costly, given each attack costs enterprises up to $50,000, according to a survey.

Prevent Shutdowns

A single server risks breakdowns due to software malfunction or physical damage. For instance, all it takes is an influx of users to overload the server and bring the site offline. Every site owner knows how much going offline can harm business, ruining traffic and disrupting sales.

A CDN doesn’t let that happen because it automatically redirects requests from an unavailable node to the next nearest one to the website user. The result: everything works and sites remain unscathed, even if demand skyrockets.

Scalability and Website Growth

Websites change and evolve as they grow and the business moves on up. However, with that forward drive comes new challenges to which business owners may be unable to react quickly regarding website model changes. 

Modifying a site’s conventional web model setup can take a lot of time – and cost a pretty penny – so fast reacting to changes and demands isn’t always possible. Despite this, CDN providers can facilitate this process by utilizing an extra node for a small fee, which is usually quick.

A CDN must deliver easy and seamless scalability, enabling companies to enjoy the cost advantages of economies of scale as they evolve. Good CDNs treat their clients equally – whether they’re a big global brand or a small startup. Whatever the case, a company can add network infrastructure at a fraction of the price of running its own server farm

Be it a video gaming site, an IPTV platform, or a rich media content outlet, a business’s bottom line can benefit from using a CDN in its network strategy. Companies can concentrate on content and sales instead of content delivery woes, letting the CDN work its magic on bringing it to users quickly and efficiently.
