The best cdn for your website or wordpress: what are they and what is it for?

In the world of web hosting, CDN technology has gained recognition to the point of becoming a very important and necessary point for website and Wordpress owners. This is why we must use the best CDNs for our sites, but first we must be clear about what this tool is about and what it is for.

What is a CDN?

These acronyms, CDN stand for Content Delivery Network, that is, content distribution network, and is a set of servers that have copies of the same content chain, which can be images, videos, documents, etc., and which are located in different points of a network to be able to serve the contents efficiently. In other words, simpler, this technology allows various geographic nodes to distribute content to users according to their location, making a much faster connection, while balancing page requests to the site and saving resources to the server of your web page.

We recommend reading the best free public DNS servers.

The architecture of a CDN is as follows:

• Content delivery component: it has an origin server and a group of substitute servers to repeat the content. Request Routing Component - Users directly urge substitute servers. These also interact with the distribution component to update and maintain the content. Content distribution component: this moves the information from the source server to the substitute servers and ensures robustness. Accounting Component: Aids usage-based billing and traffic reporting. It also keeps records of server usage and customer access.

CDN technology involves as we just mentioned a network of rationed servers around the world. The static content of a website is cached and stored on each server. This static content may include streaming audio and video, HTML, images, CSS, typefaces, and javascript. The growth of multimedia content on websites forces us to look for a fast platform to be able to serve surfers efficiently, so we must rely on the best CDNs, who are the best tools to meet this requirement but also have their disadvantages.

Websites that do not use CDN work on a single server, but all visits are in the same place, so they are all served by the same server. In contrast, the websites that use the best CDNs still use a single server, but the information is delivered to the user through a number of servers according to the location where the user is located.

Going into more detail about what a CDN is for…

In general, the best CDNs are used to save and distribute the static content of a website, but also for the distribution of the main information of a website or other media such as streaming audio. In any case, the objective will always be the same, and it is to make the distribution of all content more efficient and reliable through the elimination of bottlenecks and the proximity to users. Furthermore, these servers are usually worked by third parties, allowing companies to forget about their creation or maintenance.

The use of CDN, as we have already mentioned, works to alleviate the load on servers through the distribution of content on the network nodes, allowing an increase in the number of visitors with a better and greater connection. Also, using the best CDNs, you will be able to have a website that is always online, since the information is cached even if the server that stores the information suffers a crash or intermittent.

But, in addition to alleviating the burdens and getting better user traffic, the best CDNs work for another set of aspects on your website. By delegating the work of delivering static content to the CDN, this technology focuses on creating dynamic content, just like Wordpress does. Also, the consumption of server bandwidth is reduced, since much of the heavy lifting is done by CDN. Another utility that CDN has is that it blocks spammers, fake bots, scrapers, and even protects your website from DDoS attacks since it does not attack your node, but rather one that is already better prepared for these attacks.

With this tool, you are undoubtedly removing geographical barriers when serving your content without any limit around the entire planet and allowing it to load and position itself just like in your own location.

All these utilities that a CDN provides are intended to benefit both the user and your page in terms of achieving a better search engine ranking, you can even save yourself a lot of money, since the resources and memories on the servers have Very high prices, but using a CDN you can use very little money or you can also get it for free and with an excellent result.

Most of today's big websites use the best CDNs. Pages like Google and Microsoft have their own data centers where they manage their own CDNs. Other websites such as Facebook or Wordpress, like other high traffic networks, use the best CDNs for high level, however, these fit all pockets, what if you must be clear is that it is not a luxury, but of a necessity to be able to optimize your website or Wordpress.

What are the best CDNs for my website and Wordpress?

After knowing and knowing what a CDN is, it is time to tell you which are the best and what service each of them offers you.

CloudFlare: The most popular and free service

It is the most popular among CDNs since it incorporates a free version that is more than enough for the functions we want on our website, although there is a payment option… but it is not recommended at least for the moment.

It is one of the options that I like the most because it has a lot of POPs (More than 100 servers) spread all over the world, for example from Asia, Africa, Europe and America. The only question that we take into account is that it is a CDN with reverse Proxy and we must change the DNS of our web server to serve as an intermediary with CloudFlare.

What is the difference between the paid version and the more basic paid version, that is, the PRO? Basically they are optimized for high traffic websites and need higher performance and basic security. But for a regular website, I would not recommend opting for another service offered by the company. Another fact to keep in mind that the main cache plugins have an option to link them and save you many incompatibility problems.

MaxCDN

It is one of the favorite options of many web optimizers since it offers excellent performance and has great options. But its biggest drawback is that it only offers payment plans and that can be a problem… although its fee is not high, but why choose it if CloudFlare gives you almost the same but for free? Currently they have about 20 nodes but they forget southern Europe and Africa.

Among its advantages, it offers 30 days of free trials, 24/7 help, they help you integrate it correctly with Wordpress and high levels of security.

Amazon CloudFront

What Amazon does not do, nobody does, well yes… Google. In this case, Amazon CloudFront is a high-performance CDN and one of the safest in the world with more than 40 connection points around the world.

Just as we talk about nice things, we must comment that it is difficult to configure and that cache plugins already take it into account as (W3 Total Cache or WP-Fastest). It offers a free account that includes 50 GB of outgoing data transfer and 2 million HTTP and HTTPS requests with Amazon Cloudfront .

There are more alternatives that we can take into account, but we prefer to summarize the best options that the market offers. Now we ask you… Did you know what a CDN is? Have you ever used it? We are very interested to know your opinion.
