Running a CDN for Cloud Storage

On any website, there is a fair amount of "heavy" static content: JavaScript libraries, CSS, graphic images, all sorts of binary files ... The storage and distribution of this content always entail certain problems: we have already written about all this and told how there can be solved with our cloud storage.


Difficulties with the distribution of statics increase with the growth of site traffic. The load on the server grows, the load time of pages increases, users experience more and more inconveniences ... A huge role is played by the geographical factor: the further the user is from the server on which the site is hosted, the slower it works.


Geographical distance from end users hinders the development of many web projects and the expansion of their audience. In many regions of the world, there is still no possibility of high-speed Internet connection. Meanwhile, the share of "heavy" content on the Internet is growing, and the low speed of its delivery in modern conditions is unacceptable.


Today we are ready to help our customers to overcome distances and ensure the delivery of static content at the maximum speed.


Seconds_decide_everything:">Seconds decide everything:

It would seem that 4 seconds is very little. But according to statistics, if a web page is loaded for at least several milliseconds longer than this time, then users leave it - and never return. For commercial web projects, an extra second can result in financial losses.


Search engines, as a rule, give preference to fast working sites. First, the speed of loading pages is taken into account in the ranking formulas. Secondly, you should not discount the behavioral factor: users, who leave a slow-loading page, reduce its "weight" for search engines. Slowly working site is unlikely to be truly popular among a wide user audience. Practice shows that the speed of work significantly increases the level of attractiveness of web services for visitors.


The slow download speed of the site significantly reduces the effectiveness of contextual and banner advertising. If visitors come on the ad, but at the same time the full load of the site does not wait, it means that the money invested in advertising, in fact, is wasted: the user does not see what he should see.


The above examples more than convincingly indicate that the slow download speed of the site naturally entails serious problems.


Of course, the Internet is becoming faster and cheaper every day, but the inconveniences associated with the abundance of "heavy" content and slow download speeds, still do not disappear anywhere. Many sites, rich in graphics and animation, with great difficulty open from mobile devices, if the connection is via a 3G network.


Using CDN, you can solve all the problems described above and make it so that the site can be downloaded quickly from anywhere in the world.


How CDN works:

The abbreviation CDN stands for content delivery network. CDN is a geographically distributed network consisting of a main node and cracks, which are points of presence that can be located in different parts of the world. It is on them that all the "heaviest" elements of the site are cached. When accessing the main server, the user will be redirected to the nearest point of presence. Due to this, the network route between servers is reduced, and the site is much faster from the user's point of view.


Advantages of CDN:

The benefits received by site owners through the use of CDN are quite obvious:


·        Increase the speed of delivery of content. A user from anywhere in the world can receive content on the optimal network route for the minimum amount of time and from the nearest point;

·        Reduces the load on the main server. All the heavy content users will download from the caching servers, and due to this, the load on the main server will significantly decrease. The information stored on it will only need to be kept up-to-date;

·        Reducing the cost of infrastructure development. Using CDN allows you to save considerably on infrastructure development (all "heavy" information is distributed by caching servers, and you do not need to purchase additional equipment for its storage and distribution).


Many of our customers use the storage to share files with friends and colleagues. As a rule, these are large files: for example, photos, audio and video recordings, typographic models. Thanks to CDN these files can be downloaded at high speed from anywhere in the world.


Comparing the speed of downloading the site through MaxCDN, CloudFlare, and KeyCDN:

The speed of loading the main page of the site I measured by the service several times, sometimes I checked the results with service, and the DNS update checked Let me remind you that the download speed of the site without CDN in Los Angeles was 9.2 seconds. When configuring MaxCDN and KeyCDN, I installed and configured the WordPress W3 Total Cache plugin, which also gave a speed increase. As a result, I got such results (in parentheses the percent increase in speed is indicated):

·         "Naked" website - 9.2 seconds.


·         W3 Total Cache (without CDN) -  6.9 seconds ( + 25% )


·         MaxCDN - 5.9 seconds (+ 36%, since 25% gave W3TC, then we really get an increase of 11%)


·         CloudFlare - 7.5 seconds ( + 18% )


·         KeyCDN - 4.2 sec (+ 54%, since 25% gave W3TC, then we really get a gain of 29%)


Thus, the most strongly (29%) accelerates the site KeyCDN, in the second place CloudFlare (-18%) and worst of all MaxCDN (-11%).  And a very good speed increase (-25%) gives free plug-in WordPress W3 Total Cache!

It is easy to integrate with WordPress (manual -, as well as with Joomla, Drupal, etc. After the first year of use, the price increases to $ 99 / year for terabytes.

MaxCDN, CloudFlare or KeyCDN? Summarize!

On the question of which CDN is better, we cannot give an answer, since my research is neither complete nor objective enough, but for myself, I chose KeyCDN, because it is many times faster and cheaper than MaxCDN, and if I would definitely need a free CDN, then I would choose CloudFlare. And I would not forget about the free plugin WordPress W3 Total Cache.
