Over 50% of customers who enjoy shopping at online stores point out that their loyalty is determined largely by the velocity of website downloading. Such statistics prove the significance of CDN application in an e-commerce business. However, let’s start from the beginning.
What CDN really means
You might know that CDN refers to Content Delivery Networks. It’s a great tool to enhance specific web server operation. CDN also works perfectly to decrease traffic volume.
Specifically, CDN is considered to be a combination of several servers which have special software for final users to obtain data much faster. Mentioned servers should be arranged worldwide to minimize the time period to get feedback. In most cases, content involves some statical components along with video materials of mobile platforms and websites. Typically such features don’t need any code implementation through the web-server or any data bank inquiries, like, CSS/js.
In reality, CDN belongs to hosting types. Nevertheless, it’s not a very smart idea to make it work as a hosting server. It can be easily explained. CDN is designed to get back to the cached statical website page. CDN always takes dynamical website pages and present them in a statical manner, accumulating data in the database. Subsequently, there is no possibility to start the PHP script by means of the CDN approach striving to adopt such a tool as a basic hosting.
Who would enjoy CDN servers
Surprisingly some people engaging in the IT industry don’t actually realize the importance of CDN systems in web and app development.
There is an opinion saying if one-month traffic goes down to several terabytes only, CDN won’t really improve the situation. Although, besides the issue of dropping server pressure, remember that your users won’t be happy, in case they have to wait a long time, so brainstorm to keep latency to a minimum.
Thus, your mission is to provide services to your audience promptly. It’s not about traffic, as you should strive to get as many points of presence as possible. Those PoPs are to be as close to your final users as possible, which means that managing the CDN aspect of your e-commerce program shall become your best friend.
CDN shall be extremely useful in the following cases:
- when web-hosting imposes significant limitations on page free space, loads and so on;
- if a website or a mobile service has users from all over the world who visit the site quite often. Wikipedia is a striving example of such reality;
- if large mass-media portals provide vast space for data storage, let’s say, stocks of pictures;
- when dealing with major e-commerce plans.
Some people mistakenly believe that content delivery networks are good only for enormous websites. Yet, even little online stores or different kinds of forums, due to quick page loading, will easily stand out from their multiple competitors by means of CDN.
In case a website is designed by means of public systems, like, WordPress, their owners could think of the approaches to upgrade data delivery quality. Moreover, another valuable advantage which owners can get by means of CDN is users’ assistance and support, as it delivers detailed guidelines on such a process.

● Regulations on retention
Speaking of retention, it’s about HOW and WHEN particular element to be deleted from a web server of given PoP. Few approaches are available in here, so you can choose from timeout deleting, fixed time deleting and the cases when you delete it as you limit the quantity of requests till a specific number.
