Website Hosting Vs Content Delivery Networks

Maintaining Internet Traffic

Increasing, managing, and maintaining Internet traffic is challenging as your audience sizes begin to expand.

In the early stages when audiences are small, basic web or video hosting may be sufficient, however, increasing Internet traffic reaches a tipping point that fails to deliver the performance you need.

Establishing a reliable online presence is vital to the performance and productivity of your business, and to how your audience engages with your products and services.


What is Website Hosting?

Website hosting is the service that web hosting companies provide to make a website accessible to all computers on the World Wide Web. 

Website hosts delegate services that enable you access to website storage space on a server in a specific geo-location, or locations.

Once your website is hosted,  users can enter your domain name (for example into their browser to access your website.

Common website Hosting Issues

Even with the greatest care and attention in choosing a hosting provider, there are several common website hosting challenges that directly impact your website performance.

  • Slow loading speed or recurring downtime.
  • Lack of security.
  • Slow or unresponsive customer support. 
  • Lack of flexibility in hosting plans.

Objective research carried out by established shared web hosting plans from 32 web hosting providers, and managed their uptime for an entire year through Pingdom.

According to the research feedback, the average website is down for 3 hours per month.


In a press release, Founder of Hosting Facts, John Stevens, pointed out the uptime performance of the web hosting companies in the study. Stevens said that “In conclusion, we found out that the average web hosting provider had 760 outages throughout the year. 

Even whilst delivering “uptime of 99.59%” in the study, the majority of web hosting companies guarantee an uptime of at least 99%, and up to a  99.9% uptime guarantee (which they failed to deliver).

The Impacts of Website Hosting

With failed promises of 99.9% uptime, guarantees, and refunds from a hosting provider can never equate to the cost of a damaged reputation and significant losses in sales and operational repercussions.

According to the research, on average businesses can lose around $10.6m a year.

Whilst this loss may not be as high for a small to medium-sized business, the recovery from downtime can be a steep hill to climb, for which you may never fully recover, especially when it is for an extended period of time.

The significance of growing numbers of website users and website capacity

Even without the challenges of downtime, as companies expand and audiences grow, there’s a tipping point at which basic web hosting fails to meet the required performance and scalability standards.

Increased Internet traffic stresses key mediums like web and video servers, and the accessibility links to these digital paradigms.

With increased traffic comes slower response times for all users and with decreasing through-put, new browsing sessions simply fail.

As these issues compound, user experience suffers. Symptoms of challenged hosting capacity vary depending on the application but tend to include slow web page loading, stalled or poor-quality video, high latency on live video, and file downloads that take too long or fail altogether and need to be restarted, sound familiar?

It’s All About Access


There has been a great deal of activity in the edge computing space and the motivations for CDNs are clear.

Gartner pegged the combined cloud Platform as a Service and Infrastructure as a Service market at $72 billion in 2019.

Gartner sums it up:

 “Cloud computing has enabled scale, innovation, connection, and agility at the back end, but edge computing will complement cloud computing by providing more real-time value, more immersive interactions, more data production, and more intelligence at the front end — closer to where people and things exist.”

Since edge computing must be close to the end-user, different companies are pursuing strategies to gain an advantage because of location.


The need for a high-quality CDN

Whether you transit large or small data traffic, today’s environment means businesses demand constant national and internal connectivity to accomplish business-critical functions, such as website hosting, driving the need for a CDN who can deliver a network design to

High content loading speed = positive User Experience. 

If all data is located on a central server, the User Experience is negatively affected by limited loading speed. The greater the distance between two objects in communication (in this case, the user and the server), the longer it takes for the content to reach any of these objects. 

To put it more simply, the purpose of a CDN is to improve user experience and provide it with a more efficient network resource utilization. Content providers such as media companies and e-commerce vendors pay CDN operators to deliver their content to their audience, that is, end-users. In turn, a CDN pays ISPs, carriers, and network operators for hosting servers in their data centers. 

There are two key mechanisms that explain how CDN functions

: Keep important content distributed to multiple, globally distributed data centers so it is closer to end-users, and thus faster to download.

Use server optimizations based on a content type to get that content to the user most efficiently.
