Most businesses look for CDN hosting that can deliver exceptional optimization capabilities.

Fortunately, today the market has hosting vendors with state-of-the-art infrastructure using next gen, high performing equipment.

The upshot is, now CDN or content delivery network is easy to set up, more cost effective and crafted to do better than any legacy CDN in the market.

We must bear in mind that a fast website is vital for visitor satisfaction. This is more so in the ecommerce domain.

As one business manager of a small and medium business enterprise pointed out, “It is not enough if the focus is just on product branding. To stay in the race, online shoppers must be presented with good user experience”.

Good website experience can be boiled down to just three features – user friendliness, website speed and reliability.

How does CDN achieve it?

In a nutshell it caches or replicates content over several mirrored web servers, tactically placed at different locations to tackle sudden spikes in traffic.

Now let us get down to some basics.

The three basic components of CDN architecture are:

  1. Content Provider – The entity that provides texts, graphics , stories and the like for the website
  2. CDN Provider – A company that provides infrastructure facilities to content providers so that they can provide content in a judicious and reliable fashion.
  3. End Users – Entities that access content from the content providers’ websites.

How did CDNs evolve?

Over the last several years, the internet has grown exponentially. The result is - enormous growth in network traffic driven chiefly by significant broadband access, increases in complexities in the system, and content depth.

The nature of the internet is presenting complexities in delivering content to end users.

As a result, content providers experience congestion and bottlenecks due to huge demands made on their infrastructure.

Coping with such unforeseen demands puts considerable burden on a web server. In a worst case scenario, the web server, unable to bear the load can become unavailable.

It is to address such situations; businesses use content delivery network for their websites.

“I launched my website by taking assistance from a hosting service. The plan was cheap and it suited my business”, says an owner of a business firm. “But overtime my business grew and I had no other option but to take the services of a CDN provider”.

The above story is common with most entrepreneurs.

They choose CDN because it delivers some compelling advantages; a few of them are listed below.

Faster Website

The reason you get faster website is not just because the provider has built up huge network of servers. The users can access the website from a server closest to them. For example, if you are getting traffic to your India based website from the United States, the chances are your CDN host has a server in the United States as well.

Managing traffic spikes

At times businesses may witness huge spikes in traffic either due to press releases or due to promotional of a popular brand. CDN hosting can help businesses manage influx of traffic.

Moreover, we must keep in mind that CDN vendors have numerous networks of servers making it possible for the clients to scale available resources.

DDoS Protection

Companies that have experienced DDoS (distributed denial of service) know how agonizing it can be. When the traffic is routed through CDN’s servers, you have sophisticated technology managing DDoS attacks.

Summary and conclusion

There is no any doubt that the CDN segment is evolving. We are also witnessing consolidation as a consequence of acquisitions and mergers. Along with the explosion, development and consolidation of the CDN environment, innovative varieties of internet content are coming into the picture.

It is no wonder CDN hosting providers are focusing on exceptional caching and replication techniques to meet the growing demands of next generation content delivery networks.

There are several challenges that need to be overcome. These include scalability and quality of service to deliver high quality content.

Load balancing and contentment replication is also an area that needs focus. Strategies must be developed to effectively balance the load across several surrogate servers to enhance the quality of service.

The bottom line is CDNs will continue to evolve as an enabler of business promotion.
