What Is CDN?
What Is Content Delivery Network? CDN or a Content Delivery Network is a group of servers distributed across multiple geographic locations. You can place cached copies of your website across different servers located worldwide. When a person is trying to visit your website, a cached copy from the closest geographical service will be offered. Therefore, you can reduce the loading times of your web page.
A CDN is capable of caching numerous types of content, including images, web pages, and videos, in a proxy server. Hence, your visitors will be able to download software, watch movies, post on social media, check bank balances, or even make purchases without waiting for a long time to load content.

When you deep dive and look at a CDN, you will figure out that it is a network of servers linked together.

Why Use a CDN?
While understanding a content delivery network, you should also figure out why you should be using one. A CDN will assist your business in delivering content to visitors or end-users quite effectively. That’s because you can improve website performance, minimize latency, and reduce bandwidth expenses.
One of the unique features of a CDN is allowing the edge servers to work perfectly well. This will ensure that all data you deliver are correctly located in the CDN data centers. These data centers are known as Points of Presence according to CDN terminology. They will help you to minimize the overall round-trip time. That’s because they are bringing your website content closer to the visitors.
Benefits of Cdn
A CDN can offer multiple benefits to a website owner. Here are some of the most prominent advantages of content delivery network and why use cdn?
1- Increasing Availability
You will be able to increase the availability of your website with the help of a CDN. If you have hosted the website only on one server, a downtime in that server will make your website go offline. During that period, your visitors will not access the server. This can create a negative impact on your business. You can overcome that struggle by using a CDN.
2- Reduced Bandwidth Hosting Costs
A CDN is capable of helping you to take out the pressure of hosting website content on the origin servers. You will be using multiple servers to deliver assets to the visitors. This will eventually help you to reduce the overall hosting bandwidth consumption. While reducing hosting bandwidth consumption, you will also reduce the hosting expenses. This can benefit your website in the long run.
3- Increased Overall Speed and Performance
Along with the help of a CDN, you will be caching the data of your website’s servers in multiple interconnected locations. These connected servers are positioned all around the world. Therefore, you will help the visitors access your website data from the closest place where assets are available. This reduced distance will ensure high-speed data delivery to you at the end of the day. As a result, you can end up getting a faster website. Since your website’s data are distributed across multiple servers, you will have uninterrupted service and less downtime.
4- Improved Security
You may also think about using a CDN to improve your website security. For example, most CDNs come along with in-built DDoS protection. Therefore, you don’t have to worry too much about DDoS attacks coming on the way of your website. You can make sure that the targeted network or the server is not flooded with more traffic than it can handle. You can get the help of your CDN to block all those threats from even reaching the server. That’s because the traffic will be distributed to multiple servers.

For example, eCommerce store owners would expect more traffic during Black Friday. The CDN will be able to keep the website stable regardless of all traffic coming on its way during such a day. Likewise, numerous other industries can be benefited from a CDN in multiple ways.
Who Can Benefit From a CDN?
Any website owner out there can think about using a CDN. According to recent studies, it has been identified that more than 50% of the internet traffic is served through CDNs. This clearly explains the critical role that CDNs are capable of playing. The number of visitors who get through CDNs is increasing along with time.
Even small business owners can think about starting to use a CDN. That’s because there are multiple free CDN services available for them to consider. If you are running a localized website, you will need to pay attention to this. You can experience multiple benefits of having a CDN in the long run. Some of these benefits would not even be visible to you. Most prominent businesses that use CDNs now include government institutions, higher education institutions, healthcare institutions, mobile gaming companies, e-commerce stores, online gaming stores, media, and entertainment stores, and advertising companies.
However, we encourage you to think twice before using a free CDN. Free CDNs can cause unessential connection points among visitors with a nearby server. Hence, you might even have to experience a slowdown in website traffic. We encourage you to spend your money and purchase a premium CDN.
With the understanding you now have about CDNs, you may consider investing your money to purchase the best CDN available. Then you will be able to maintain the level of service as you continue to grow your website presence. Due to all these reasons, a scalable and reliable CDN can be considered an excellent investment in your future.
