Although websites are not the main means of dissemination in most business areas, they are still positioned as an essential engine for the user to choose to stay with a specific brand. Those who offer products or services must do everything possible to satisfy the customer’s needs on time. One of the allies is providing access to your website much faster, without implying too high an investment of money. Today we are going to show you what a CDN is, how it works, and what are the Best CDN that you can use to Optimize Website Loading Speed.
What is a CDN?
Its initials correspond to Content Delivery Network, in Spanish, this means « Content Delivery Network ». A CDN is a set of servers interconnected through the Internet, the main function of which is to speed up the loading of websites for users. They do this by getting the cache of virtually any website. On the other hand, that cache is stored on its servers that can be located anywhere in the world.
Do you know what is best of all? It does not matter if you have visitors who are located on the other side of the continent. Each one of them will be able to enjoy a high loading speed of your website. CDNs, together with Load Balancers, are two tools to have a website with an excellent user experience. However, you may not be very clear on how to implement it initially. Therefore, several providers greatly facilitate the task of doing it, we can even find quite well-known providers that offer free plans.
It doesn’t matter if you have a small, medium or large website, everyone can access a CDN solution. You are likely to save on costs if you feel that the free plan meets your needs. Or, you can opt for a wide variety of premium plans with variable costs according to need. For example, in the ADSLZone Group we use the Transparent CDN CDN, which is a Spanish company.
Scheme of operation of a CDN
Once you have chosen the CDN provider of your choice, a large part of the work is done by that provider:
- The content delivery network makes copies of web pages and transports them to a network of servers that are scattered in different locations. This transport process is called « caching » in English, it means creating a copy.
- If a user requests access to a web page, and it is part of this CDN network, the access request is automatically redirected by the CDN itself to a member server. The member is chosen based on the user’s geographical proximity, that is if our website is hosted in Spain, and we have a CDN server in the US, if they connect from that country, the request will go to that nearby US server, and not to the origin (Spain).
- After having located the server, this server delivers a copy of the original content of the web page. That is the cache of the requested page.
An important point is that the CDNs communicate with the different web servers of the sites, to constantly generate the cache of the content that has not yet been detected. This process is completely transparent to the user.
There is a tool called CDN Finder, from the CDN Planet company, that will let us know if a certain website uses a CDN. It is a website that does not require you to register if you want to consult information about CDN. Simply enter the URL and in a few moments you will get the desired information:
To be even faster, we can simply modify the URL:
Where it says www.droidcops.com you can indicate the website you prefer, always indicating if it is Http or https. Then you give Enter and you will directly get the CDN Finder page with the results.
8 Best CDN to Optimize Website Loading Speed
1. Cloudflare : Optimize Website Loading Speed
It is one of the most popular CDNs when it comes to web services. It is used by super-popular services like Zendesk, Digital Ocean, the Udacity course portal and the popular Discord. It is characterized by wide adoption since it is quite easy to use, despite not having much technical knowledge.
Anyone who chooses Cloudflare as a CDN provider will be able to enjoy multiple features that will benefit their website. It is not necessary to edit some type of code, it simply indicates the names of DNS servers ( nameservers ) and the service starts operating as soon as possible. Start generating a copy (cache) of the pages that make up your website. And as we already know, all that cache is directed to the servers that are part of the CDN that are located in various locations.
It has additional functionalities such as web content filtering. Which can block bots, unwanted content (spam) and most importantly, protect you from cyber-attacks? We know that DDoS attacks are largely carried out to leave websites of all kinds, especially powerful ones, unworked. On the other hand, if your website frequently uses images, it optimizes them automatically up to 35% using an intelligent optimization system.
Cloudflare supports modern services like IPv6, HTTP / 2 and SPDY. For your consideration, the latter is a protocol that is responsible for optimizing the fluidity of communication between client and server, which greatly contributes to the loading speed of websites. Besides, to further increase the security of the site, it has a vulnerability scanner called Flan Scan.
This service is, without a doubt, a benchmark throughout the world, and also has very interesting additional services. Let’s see what plans you have available, and what each of these plans offers us.
As its name suggests, it is the free plan that Cloudfare offers, ideal for small websites, blogs for personal use. In this version it offers mitigation of unmeasured DDoS attacks, global CDN, shared SSL Certificate and 3 rules per page. It also offers an “I’m under attack” mode where all the defenses of the CDN will be activated to prevent them from knocking down the website, thus mitigating the attack.
Like the free plan it offers us the same as the free one, but adding a web application firewall (WAF), image optimization with Polish, mobile accelerations with Mirage, and 20-page rules. It costs $ 20 a month per domain.
This plan adds everything from the previous plans (Pro and Free), but also adds the following features:
- Priority email support
- It allows choosing the “TLS Only” mode to protect all communications at all times.
- Uploading a custom SSL certificate
- Skip cache memory in cookies
- 50-page rules
- The WAF firewall allows you to configure it with 25 custom rules.
This plan is priced at $ 200 per month per domain. This plan is aimed at small businesses and e-commerce websites that need to have guarantees of security and operation.
In the Cloudflare Enterprise plan, in addition to all the above of the other plans, it adds operation and security of enterprise-grade with uninterrupted assistance by phone, email and chat, they also guarantee 100% uptime, something that with the others plans does not happen.
It also has several custom SSL certificate uploads, access to records, priority in the CDN network, includes 100-page rules, access to China’s data centers, role-based account access. The price is personalized according to the needs of each company, but logically it will not be cheap.
However, all these features that we mention are included according to the plan you choose. You can enter the official portal where you can take a look at the list of available plans, including the free one.
2. Transparent CDN : Optimize Website Loading Speed
Transparent CDN is a Spanish company, it could be said that they are the Spanish Cloudflare. This company offers us a series of very interesting features, such as, for example, that it has CDN servers spread throughout Spain so that all websites always load as quickly as possible.
Transparent CDN has caching algorithms that allow web pages hosted on its CDNs to load up to 10 times faster. The entire ADSLZone Group is on the Transparent CDN. Of course, this CDN provides us with a «Transparent Secure Layer», basically it is the technology that mitigates DoS and DDoS attacks that different web pages could suffer.
The last option that we can highlight from this CDN, are its services that allow converting videos on demand VOD, or live videos in all formats so that they are distributed on all devices and platforms. This happens thanks to Transparent Transconding Services, Live Streaming Services and Transparent Storage. Transparent CDN does not charge you for requests, invalidations or registered domains, you can have as many as you want.
We recommend you access the official website of Transparent CDN plans, where you will find all the information on prices, technology used, and the contact form.
3. Akamai CDN : Optimize Website Loading Speed
One of Cloudflare’s main competitors is Akamai, it is another of the companies that we must take into account when choosing a CDN service. The negative part of Akamai is that, to know its prices, we must speak directly with its commercial service, we will not find the prices on the official website.
Akamai’s CDN services rely on three software components to stand out from the competition:
- Aura Edge eXchange: It allows us to offer online video content and commercial services, based on a SaaS solution, which allows us to implement the services quickly and at the minimum initial cost and without complexity.
- Aura Control System: It is a set of unified tools that allow the interconnection of all the products and services that Akamai offers. Thanks to this, you can manage errors, configuration, account, performance and security problems.
- Akamai Federation: Serves so that its clients can join Akamai Intelligent Platform, this platform is the largest Cloud Computing network in the world, according to Akamai. Thanks to this, customers will be able to better distribute their content.
And this, broadly speaking, is what Akamai offers to differentiate itself from your competition as Cloudflare. We recommend you visit the official Akamai website where you will find all the information about its service.
4. Fastly : Optimize Website Loading Speed

The need for immediacy on the part of users can be covered by solutions such as Fastly.
On the other hand, you can manipulate the HTTP headers, to customize the way the content of the website is being transmitted. Of course, if the need indicates so, you can choose this interesting facility.
However, the fact that you have a wide range of configuration options can be a problem. Especially because users who do not have much knowledge about website configuration, can get a bit overwhelmed. This CDN provider is geared towards larger-scale sites and of course, more experienced administrators.

One of the aspects that characterize Amazon CloudFront is the great ability to provide analysis tools, which show you very interesting details regarding visiting users. For example, you can know about the devices they use to navigate your site, operating system, and its version, among other advanced aspects. It is also possible to configure alerts that inform you if the data transfer exceeds the established level.
As with Fastly, the benefits offered by Amazon CloudFront are quite a few and the way they are configured can intimidate some people who do not have much experience. However, if you already have experience, it is one of the best options you could choose from because Amazon has a high level of reputation, technology and support for practically all the products and services offered.
On the other hand, and as is characteristic of Jeff Bezos’ company, how costs are calculated is not entirely familiar to most. However, if you want to opt for Amazon services, the ideal is to go to the cost section and review their details.
