If your company’s website is gaining significant success from geographically distant users, you need to know immediately what a CDN network is.
However, providing a site that makes content immediately available to please the user and rank in search engines.
However, this speed is directly related to the physical location of the server. This means that the farther the user is geographically, the longer the page will take to load.
Fortunately, there are distribution networks, such as CDN, that improve website access speeds even when people are away from the server.
With it, you can rank on Google and still allow your visitors to have the best browsing experience on your page.
Want to know how to achieve this feat? Then keep reading this content!
What is a CDN?
CDN stands for Content Delivery Network, its function is to allow caching of website content. But what does that mean?
Well, that means duplicate content stored on the main server. This version, in turn, is preserved in Points of Presence (Pop), which are scattered all over the world.
With this, the hosting bandwidth is reduced and the user who is in Australia, for example, can access the Canada site quickly and seamlessly. Amazing, isn’t it?
It should also be noted that there are three types of CDNs, namely:
1: Private Networks: Their access is limited to a small group of people. In this sense, they act as their own cluster of servers.
2: Content Service Protocol: These networks provide website content. They are designed, hosted and configured for this purpose.
3: Peer-to-peer (P2P): These are networks connected between private computers.
How does a CDN work?
When a CDN occurs, the servers that are part of the network copy the contents of a given site and store them in a cache, which is a memory. This copied version of Points of Strategic Places, Points is saved worldwide.
Thus, when the user accesses the site, the CDN searches for the nearest Pop and, if there is no such distribution network, provides the required content with extremely fast and high throughput.
To better understand you, when there is no CDN and the user tries to access a website, the computer sends a request for access to the content to the central server. Then, the server responds and shows what has been requested by the individual.
In this case, the delay time (the time between the request and the response) can vary considerably, with the user physically longer than the server.
On the other hand, when you have a CDN, the user’s access request is redirected to a nearby server, not the central server, which already has a copy of the content.
A mapping system is used to verify the user’s location so that a close copy can be provided.
And if, for a given case, the data has not yet been copied and stored, Pops negotiate with the central server to deliver the content, thus meeting future needs.
It should be noted that in addition to speed, CDN also makes it possible to distribute traffic evenly among different servers. At the same time, the chances of site instability are greatly reduced due to the large number of hits.
How does using CDN benefit your website?
You can already see that CDN has a lot of advantages, right? However, to further illustrate the benefits of a content delivery network, we’ve listed all of its benefits. check this out!
Improved loading time
The main and obvious advantage, of course, is the improvement in site loading time. After all, as you can see, the responses are very fast and the delay time with CDN is significantly reduced.
And it’s worth noting that it can make a huge difference in ensuring your user experience. This is because for Internet users, who always want a quick response, an extra second can make a difference in their perceptions of your site.
Greater security
As the response time with CDN is reduced, so is the weakness of the website. This is because hacker attacks miss out on the fraction of seconds that would be important to hack into the system.
DDoS attacks itself, and those who try to bring down the website and make its resources unavailable to users also lose power.
In addition, CDN manages the traffic the website receives to ensure that it is always up and running, thus preventing malicious attacks.
Cost reduction
CDN can also significantly reduce the costs involved in maintaining and running a website. This is because it promotes lower bandwidth consumption, which reduces costs with this infrastructure.
In addition, because access is decentralized and therefore, the load on the central server is less, costs can be reduced.
Therefore, it is possible to save a significant amount that can be used to implement other key strategies in the company.
Infrastructure
The infrastructure is also a huge advantage for any small live streaming service because of how easy it is to get the entire CDN infrastructure ready for immediate work without any investment. It’s natural that big platforms like YouTube or Twitch will be able to build their own CDN networks, but smaller services often don’t have that amount or capability – that’s where the CDN service comes from.
What features does a CDN solution offer?
When a CDN solution is contracted, in addition to the basic work we describe here, it also offers other features that can be used to further enhance a website’s performance. Meet some of them:
Conclusion
Now that you know what a CDN is and how it can benefit your business, whether it’s improving the user experience, ranking your business on Google, or your web. Bring more security to the site, now is the time to take the next step!
