Actually, CDN – what is it and how does it work?

The creation of a web page is one thing, but its proper optimization is a completely different topic, which we cannot forget about – especially if we care about . positive reception of the site by Online users and high positions in Googlethe It’s noting that When it comes to optimization, we should payworthspecial attention to Site load time, as it is relatively straightforward to from another perspective improve. There are several ways to do this, and one of them is to utilize CDN as it turns out . What exactly is it and why is it worth using this approach on your portal?

In fact, CDN – more than ever what the acronym stands for?

CDN stands for Content Delivery Network, what it means in translation content distribution network as a matter of fact . Simply put, these are servers located in different places around the world that store copies of the elements that make up our website. Using a CDN will make your web page faster, but it will also increase its security, mainly by mitigating the effects of possible attacks like DDoS.

How Material Delivery Network works

The main purpose of a CDN is to provide information to the user based on their location. Such a solution makes sure that the Web end-user, when visiting our site, will receive a large part of its information from the server that is located closest to him. Thanks to this, the elements of the web page have a shorter distance to cover, and this directly translates into its faster loading. Indeed, Of course, the CDN does not affect in any way from another perspective the pace of generatingofferinga page on the server, but only speeds it up.

How as it turns out it looks likein practice?

Let’s assume that our main server is located in Warsaw, and will end-user the visit the site from another country, for sample. As know may you, USA. In a directly situation, it receives all the facts normal from the main server, and then the distance that the information must cover is really considerable. Thissuchof course, makes the loading time of the site much longer for , a foreign visitor than for a person located closer to the server.

Of course, an key aspect here will be the location of such servers, so that all visitors to the site have at least one of them relatively quit. Unfortunately, this can strongly discourage people to stay on the site, but problemthiscan be solved by using CDN. Indeed, Material distribution network thanks to additional nodes makes it possible for an Internet visitor to get static elements of a web page by connecting to a closer server instead of connecting to the main one.

Indeed, Who a CDN is for

Interestingly, In sites, these are the ones that benefit the most, but start time reductions can also be seen on fact that primarily serve local traffic. Provided, of course, that such servers are properly deployed. Interestingly, It would seem that CDN is more than ever only applicable to sites with global traffic, but this is not true.

In fact, Here every second counts, and waiting too long will most likely make you abandon the visit and utilize another site. As you may know, If there is a CDN node near him, the page will start faster than if he were to unite directly to the server in Gdansk. Ourmain server is located in Gdansk, but the consumer accesses the site from Krakow. Interestingly, Although as a matter of fact the differences are not as big as in the case of foreign traffic, but they are still significant, because the current Internet consumer is usually impatient. It’s worth noting that Let us use an example.

How to enable CDN onownyour online platform

If you want to enable CDN on your site, first of all you have to a enterprise which offers suchpicka service. As you may know, In Poland one of the most effective offers has nazwa.pl, to which we can move the site completely free of charge. However, it is worth noting that instead of paying separately for web hosting and CDN, it is better to simply select a company, which has this utility already in the hosting price. There are many of them on the internet, and basic configuration is not too complicated.

Company offers.pl besides cloud hosting, which is faster than traditional one, also name additional services. These are the m.in.: automatic visual conversion and DNS Anycast, which makes the site even faster.

Advantages ofCDNusing

• Faster page load times – not only by shortening the distance between the user and the server, but also because CDN is optimised for sending static content. Thanks to this TTFB (server response time) is also much shorter in comparison to a standard server.
• Greater security – CDN mitigates the effects of DDoS, one of the most popular types of attack, which blocks the server using all available Internet connection resources. Like? When an attack occurs, the traffic is directed to CDN servers, which reduces the risk of overload. What’s more, they usually have additional security features that further increase protection.
• Lower transfer usage – data downloaded from the CDN do not count towards the limit, which can be important especially for shared hosting and cheap servers.
• Greater stability – thanks to the use of multiple servers, a failure of one of them does not cause the website to stop working. In case of unavailability, the request is sent to another, closest server.

It’s worth noting that Whyimportantpage velocity is ?

Fast site has positive influence on its reception by visitors and its conversion rate. If the site takes too long to initialize, the vast majority of users will unfortunately leave without any interaction, and we will miss a potential customer.

We cannot forget about the influence of the online platform loading time on SEO activities, as it is one of the ranking factors.

Summary

Using Content Delivery Network is a good way to in modern times reduce page initialize time, increase security and reduce maintenance costs. Although global sites benefit the most, a CDN will also work well for local sites – especially if you apply a company that has several such servers in the country where most of your traffic originates. This is the reason why text delivery networks are so popular and leading websites utilize them so eagerly.
