What is a CDN?
Although there’s a lot of talk about Content Distribution Networks, you probably know someone who doesn’t know what a CDN is. In this article, we’ll clear up any conceptual doubts surrounding the subject.
CDN stands for Content Delivery Network.
It is a network of geographically distributed servers that store copies of data such as images, videos, audio and web pages. This way, this content can be delivered quickly to users all over the world.
How important is the CDN?
The CDN helps to improve the speed and availability of content, increasing user satisfaction and sales conversion. The CDN also helps to reduce the load on the original servers, avoiding overload problems and guaranteeing data security.
Main benefits
-
- Increased loading speed: Content is delivered from your nearest server. In other words, the content is loaded more quickly, rather than having a long way to go to the original content.
-
- Availability: With servers in various locations, the CDN ensures that content is available to users all over the world, even in remote regions.
-
- Improved security: The CDN can be configured to offer protection against DDoS attacks and some types of vulnerabilities, such as SQL Injection, XSS, among others. This way, your site is less susceptible to interruptions or problems with intrusions.
-
- Reducing server load and consumption: By storing copies of the content on distributed servers, the CDN helps to reduce the load on the original servers, avoiding overload problems and generating financial savings.
A CDN network is ideal for any type of content that is accessed by users, such as images, videos, audio, files and web pages (HTML, CSS, jQuery, Javascript, etc.). In addition, it is especially useful for sites with a high volume of traffic, such as e-commerces, social networking sites and online games.
Conclusion
A CDN is an essential technological solution for companies that need to deliver digital content efficiently and quickly to users in different regions of the world. They also offer additional security features to protect against cyber threats.
With the continuous increase in internet use and the need for a high-quality user experience, CDNs play a key role in ensuring access to content quickly, securely and reliably. As a result, if you want to stand out in a highly competitive environment, you should seriously consider using a CDN in your digital content delivery strategy.
