Why You Should Invest In CDN (Content Delivery Network)?


A Content Delivery Network (CDN) is a globally distributed web server or Point of Presence (PoP) network which aims to provide a faster distribution of content.

In the CDN (content delivery network) the content is distributed and processed so that the user can access the data stored at a location closest to the user. This is different and more effective than conventional methods of storing information on a single, central server.

Similar to all clients who use the same central repository, a client accesses a copy of the data that is similar to the client to avoid bottlenecks outside the system.

A Content Delivery Network (CDN) is an integrated online network system that delivers web content to different users quickly by duplicating or caching content on different servers and routing content to nearby users. A content delivery network (CDN) platform seeks to deliver content to high-accessibility and high-performance end-users.

When an end-user requests a specific web page, video, or image, the distribution of a server closest to the user is dynamically determined and the processing speed increases. Hundreds of thousands of servers can replicate content to deliver the same content as possible to as many people, even when used in full.

Companies that have rich digital content on their platform and want to deliver the same easily and efficiently to their customers can use CDN, in the media, entertainment, sports, technology, online shopping, and many other applications. Consumers want an online experience of high quality whether they're watching a video, attending an event, playing a game, or shopping online. The use of CDNs leads to increased performance and thereby offers more customer service for end-users. Global demand for content distribution network services is forecast to reach about $6.9 billion in 2017.

Why must you invest in CDN?

Content Delivery Networks (CDN) is a cloud infrastructure that is installed at various geographic locations to manage increased traffic loads and reduce the delivery time from servers to the user. CDN 's main aim is to offer content to users in various geographic locations at peak speed and this is achieved through a replication process. CDNs offer Web content services by duplicating and routing information from other sites to users from the nearest data center. The CDN determines the shortest possible route between a user and the Web server based on factors such as speed, latency, proximity, availability, etc.

Social networks, media and entertainment websites, e-commerce websites, educational institutions, etc. make extensive use of CDNs to rapidly deliver content to users in different locations. Organizations are benefiting from adopting CDN solutions in many areas including,

  • Faster loading of content/response time to deliver content to end-users.
  • Disponibility and scalability, since CDNs can be integrated with cloud models
  • Content redundancy minimizes errors and no additional, costly hardware is required
  • Improved user experience with CDNs, since they can handle peak time charges
  • It addresses issues of data integrity and privacy

It gives a boost to your reliability

A high-performance website is tantamount to high conversion and rising sales. Problems with latency and speed continue to cripple web companies and cause harm. A couple of seconds may signify the difference between a successful conversion or bounce. A secure CDN ensures the load speed is more than sufficient and smooth transactions are made online.

CDN Helps In Your Global Reach With International Audience

Over one-third of the world 's population is online, which means that the global use of the internet has increased exponentially over the last 15 years. CDNs provide solutions through cloud acceleration with local POPs. Its global scope would remove any latency problems that disrupt online transactions over long distances and cause sluggish load times.

A CDN Offers Great Customer Support

Price CDNs were renowned for outstanding customer service. In other words, there is a standby CS team available to you at all times. Whenever anything happens, you have a backup that is waiting to help you fix issues related to your results. Getting a support team on a fast dial is a wise business move-not only do you pay for a cloud service, you pay for a wide variety of services that help your company expand internationally.

Money-Saving Process

Hiring CDN results in significant savings for a company; instead of investing in a network and different service providers globally, a multinational CDN will remove the need to pay for costly international hosting and therefore save a lot of money for your company. A regional CDN provides a common network to manage all the various operations at a fair price, operating across multiple regions. CDNs are also recommended for tightly budgeted companies.

Provides Protection Against DDoS

Apart from causing massive economic damages, DDoS attacks may also have a significant effect on the targeted business or organization's credibility and picture. Whenever customers type in their credit card numbers to make an online purchase, they position their trust in that company. DDoS attacks are on the rise and new ways of Internet security are being developed; all of which have helped to boost CDN growth, as cloud security adds another layer of security. Cloud applications are designed to block an intrusion before your data center even hits it. A CDN takes over the traffic and keeps the website running and up.

Decreases The Load On Your Server

A CDN's strategic positioning will reduce the server load on interconnects, public and private peers, and backbones, freeing up the total bandwidth and reducing distribution costs. In essence, the content is spread across multiple servers, as opposed to offloading them to one large server.

Helpful In Increasing Your Users

Strategically positioning the servers in a CDN will result in a high backbone capacity of the network, which reflects a substantial increase in the number of users who access the network at a given time. For example, if there is a 100 GB/s backbone network with a capacity of 2 TB/s, it can only deliver 100 GB/s. With a CDN, however, at 10 strategic locations, 10 servers will be available and can then provide a total capacity of 10 x 100 GB/s.

CDN Works Where Traditional Boosts Stop Working

To be frank, current technology and traditional web hosting are no longer able to meet the websites' demands. A CDN, made up of edge servers that are deployed in various parts of the world, now plays a significant role in surpassing the computing capacity of conventional web hosting to deliver efficiently and cost-effectively rich and high-quality multimedia content.


Another common misunderstanding is that there is a big price tag associating CDNs. And indeed this is true for some CDN providers. The prices are therefore very affordable with KeyCDN (see CDN pricing page). As you see speed increases, the small investment is worth it.

The bandwidth costs are usually lower than with a conventional hosting service. And as you saw above, it normally takes at least 60 percent + of the load off your origin server while using a CDN. By using advanced CDN features such as the Origin Shield and hotlink protection, you can increase your bandwidth even further.

CDN Offers Better Conversion Rates

The fact that boosting your pace will improve your conversions has been proved time and time again. This is due largely to the fact that you deliver a great user experience. 46 percent of users will not return to a poorly performing website according to LoadStorm. And 74 percent of users would give up on loading a web app after waiting 5 seconds.

  • In session-based conversion, the user base saw a 1.11 percent boost for every 100 ms decrease in the homepage load level, amounting to an estimated annual sales rise of $376,789.
  • For every 100 ms decrease in load page checkout speed, customers saw a session-based conversion life of 1.55 percent, amounting to an average annual revenue increase of $526,147.
  • An increase of one-page view per user results in a 5.17 percent lift in user-based conversion, i.e. for each additional page viewed per user, saw annual revenue increase by $398,484 for its average customer.

Offers Automatic Availability

CDNs have automatic server availability sensing mechanisms with instant user redirection, due to the distribution of assets across many regions. As a result, 100 percent availability of CDN websites is encountered even during major power outages, hardware, or network issues.

CDN Offer Great Help In Analytics

In addition to being able to deliver content at a rapid pace, content delivery networks may also provide invaluable analytical data to uncover patterns that could contribute to advertisement sales and expose the strengths and weaknesses of your online company. CDNs can provide real-time load statistics, optimize per-customer capacity, display active regions, indicate which assets are popular, and report viewing details to their clients. Such information is particularly relevant because logs of usage are deactivated until the source of the request has been applied to the CDN.

Different Areas Where CDN Is Used

CDN is used in several areas where expert knowledge is required. Let us have a look at some major areas where CDN is needed:

Media and Advertising: In media, CDNs boost the efficiency of streaming content to a large extent by rapidly delivering the latest content to end-users. Today we can easily see, online video and real-time audio/video and other media sharing applications are rapidly in demand. The media, advertisement, and digital content service providers are exploiting this demand by efficiently providing high-quality content to consumers. CDNs accelerate the distribution of different forms of media content such as breaking news, videos, music, video gaming, and mobile games. The service is made accessible from the data center that is nearest to the position of users.

Ecommerce: E-commerce companies use CDNs to improve the performance of their site and make their products available online. CDN offers 100 percent uptime of e-commerce pages, according to Computer World, and this contributes to better results on the global website. Enterprises can retain existing customers with continuous uptime, leverage new customers with their products, and explore new markets to maximize their business outcomes.

Education: CDNs offer many advantages in the field of online education. Most educational institutions offer online courses requiring streaming of video/audio lectures, presentations, pictures, and systems for delivery. Students from around the world will take the same course in online courses. CDN ensures that the content is served from the nearest data center to the student's location when a student logs in to a course. CDNs support educational institutions by directing content to areas where most students live.

Websites Related To Business: CDNs accelerate user-website interaction, this acceleration is highly essential for corporate businesses. Velocity is an important metric and a ranking factor in websites. If a user is far from a website the web pages are loaded slowly. Content delivery networks solve this issue by sending requested content from the nearest server in CDN to the user to provide the best possible load times, thus speeding up the delivery process.

The internet is a wide set of networks or data centers. In addition to computers, the growth of the worldwide web and related technologies along with the proliferation of wireless technologies, cloud computing, etc. leverages users for accessing the internet with multiple devices. Online servers that are installed in internet networks account for most internet consumer requests. But when web servers are located in a single location multiple workloads are becoming increasingly difficult to handle. This affects the performance of the website, and significantly reduces efficiency.

Content Delivery Networks (CDN) accounts for a wide share of website users and networks across the globe providing the content. The content contained on today 's websites includes several formats including text, scripts, documents, photographs, apps, media files, live streaming media and streaming media on demand, and so on. CDNs are deployed in data centers to efficiently deliver such diverse content to users all over the globe. CDNs accelerate website performance and provide users and network infrastructure with various benefits.
