CDN services help a business to speed up the work of a website or online resource, optimize the playback of video content and organize uninterrupted online broadcasting for an audience of any size and territorial distance

Why Content Delivery Networks (CDN) Technology Is Needed 

The Internet is the main source of communication with the outside world: from telecommuting and education, shopping for goods, food, household appliances and real estate to communicating with friends, colleagues, family and friends. Every year there is more and more “heavy” content on the Internet, and the popularity of streaming services is gaining momentum. 

The speed of loading and operation of online services directly affects audience loyalty: in today’s dynamic world, no one is used to waiting. Also, modern search services evaluate the loading speed of a website and an online resource. The higher the loading speed, the higher the site will be in the search engine results. For example, Google ranks pages in search based on their load times, and Facebook has announced that it will prioritize links that load quickly in its news feed. Facebook employees found out that people refuse to visit pages that take a long time to load. Along with a drop in traffic, business profits also decrease, so network speed is very important for the distribution of any content. 

A technical solution to speed up the distribution – CDN, a geographically distributed network infrastructure for fast delivery of content to users of services, applications and sites. CDN servers are geographically located so as to minimize the response time of the site to the user. A CDN consists of several parts: 

  • Origin – the server that stores the source files or data distributed via the CDN;
  • PoP (point of presence, point of presence) – a caching server as part of a CDN in a specific geographic location. The term Edge is also used to refer to these servers ;
  • dynamic content that is generated on the server when the request is received;
  • static content that is stored on the server unchanged.

Distribution across servers in different parts of the world provides access even during peak loads. Also, CDN helps to reduce the risk of losing access to the service due to a fall of the main server: the content will be available all the time while you are recovering. 

Who uses CDN

CDN is suitable for businesses in Russia and abroad. Using a CDN will reduce delays, provide fast content distribution and improve the user experience. 

Organizations often use CDNs during marketing campaigns, sales seasons and during those periods when the number of end customers can be uncontrollable, and the actual infrastructure of the organization is not able to process the entire volume of traffic and requests, which can lead to the fall of the organization’s website at a strategically important time.

The technology can also be useful to developers of mobile applications, recently there have been special solutions focused on distributing content to mobile devices – Mobile CDNs. Many large CDN providers offer such services, such as Akamai or Amazon. 

CDNs are also used by companies focused on the distribution of gaming, multimedia content and streaming services. If the number of users of your service is growing, look for a CDN to optimize, speed up the distribution and reduce the load on the main servers.

How to find a reliable CDN provider

The speed and efficiency of a CDN depends on the availability of interfaces with telecom operators. For example, a CDN provider with points of presence in 100 cities, but with a small number of joints, may have a longer delay than a provider whose points of presence are located in several cities, but there are much more joints with telecom operators. Unfortunately, in most cases CDN providers do not publish such information, so everything can be checked only by testing: 

  • pay attention to the number of points of presence, which is relevant for projects with an international audience;
  • check if the CDN provider supports the technologies and protocols you need;
  • clarify the information about points of presence in the regions you are most interested in and compare it with the potential audience of the site;
  • often CDN providers provide analysis of consumption statistics, management of caching policies and HTTP headers, preloading of very “heavy” content (from 200 MB), full and selective clearing of the cache.
