What is CDN?
IT can be a confusing subject. From wires to applications and software types to hardware configurations, they can be all too much for the regular joe. But when was the last time you learned a new tech jargon? If you’re looking to expand your IT vocabulary, we can start by discussing the magical powers of CDN. But what is CDN?
Here’s a simplified, re-worded definition of the term:
CDN stands for Content Delivery Network. Essentially, it is a group of servers scattered all around the globe to cater to website visitors, depending on where they’re from. If that isn’t very clear yet, CDN pertains to a globally distributed network of servers that function together to extend speedy internet content delivery.
To fully grasp how this science works, one needs to have a reasonable understanding of how regular web hosting functions, to begin with. Given the usual web hosting set-up, all the data traffic going through your site is transferred to your web host and server—the party responsible for your data and other media.
An efficient CDN also aids in securing websites from hackers that run malicious attacks.
What is CDN and is it the same as a web host?
To start, CDN doesn’t work as a web host because it's unable to host content. It also doesn’t carry the capacity to cradle web hosting necessities. It does, however, at the network edge, assist in caching content. This, in turn, enhances website performance. A lot of sites have difficulty meeting their performance needs by utilizing only traditional hosting services, hence the decision to resort to CDNs.
That established, the CDNs are becoming a fast-rising solution to relieve a few primal issues that are present with traditional web hosting such as preventing interruptions in service, and bettering overall security.
The leading benefits of using CDN | What is CDN?
The advantages and perks that come with a CDN differ as they’re reliant on the needs of an internet property and its size. The top benefits for a majority of users can be divided into 4 elements:
Improve website loading period | What is CDN?
By apportioning content closer to a website user by turning to a CDN ever nearby—this on top of other optimizations—users will notice that loading periods become faster. Because site visitors are likely to close a tab altogether once it shows signs of loading slowly, a CDN may counter this. That said, CDNs improve the staying time people are on a website. Simply put, the faster a website is, the more users are likely to stay on a site longer.
Reduce bandwidth budget allocation | What is CDN?
Through other mergers and simple caching, CDNs can lessen the data extent a web host server is required to provide. This act in itself already reduces the need to splurge on hosting costs. Know that bandwidth consumption already takes a huge slice of the costs, so CDNs help website owners save.
Improving content redundancy and availability | What is CDN?
Huge amounts of hardware mishaps or traffic can hamper an ordinary website performance. Because of CDN’s apportioning nature, they’re built to withstand mishaps relating to hardware and take on more traffic a lot better than several origin servers.
Enhance site security | What is CDN?
Because a CDN can provide security certificates, other important protection mergers, and DDoS mitigation most especially, CDNs enhance security even more.
How does a CDN function? | What is CDN?
At its simplest, as defined earlier, a CDN is a structure of servers “chained” together to deliver content as reliably, cheaply, and quickly, as possible. To ensure connectivity and optimized speed, CDNs install servers usually at exchange points that surround various networks.
The fundamental locations of these Internet exchange points are where an assortment of Internet providers connect to gain and provide access to traffic coming from these different networks. Furthermore, a CDN provider improves transit times and reduces costs simply by making use of a connection to these highly interconnected areas.
