Do You Need a CDN? Top 9 CDN Benefits Explained

You might wonder, why do you need a CDN? Or you may be searching for the benefits of using a CDN service? If yes, then you’re in the right spot to know that.

A CDN (Content Delivery Network) is a network of servers geographically distributed. They store the temporary copies of your site content in multiple locations. As a result, your visitors can access the site faster from the nearest server.

If your site has high traffic, then it’s better to use a CDN service. But that’s not the only reason why you may need this service. 

In this article, we’ll cover all the advantages of using this service to help you determine if you need a CDN or not. So, let’s begin!

What is a CDN? What are the Main Types of CDN?

First, let’s get to know about CDN a bit deeper.

A CDN is a group of servers distributed at different geographical locations yet working altogether. Every individual CDN or Edge server is called a Point of Presence (PoP).

What is a CDN?

Each PoP stores a temporary copy (cache) of your site’s static content from the actual server your site is hosted on. And this server is referred to as the origin server. The static content can be HTML pages, videos, audios, images, JavaScript files, etc.

When a user visits your site, CDN sends the request to the nearest PoP from their location. Then, it routes the requested content back to the user. 

Nearest CDN Service

Thus, users access the content from a server near them instead of the original server. Ultimately, your site will load quickly to the users.

Now, let’s take an example for clarity. 

For instance, a person from India visits your site hosted on a UK server. Then, the site content will not be delivered from the UK server when you’re using a CDN. Instead, the content will be transmitted to the user from a PoP near India.

Types of CDN

Basically, there are 2 main types of CDN servers. They are Push CDN and Pull CDN. Both of them have their own set of distinct features. 

Selecting the CDN type you need depends on your website requirements and traffic expectation. Thus, your choice all differs according to the situation.

Now, let’s get to know its types. So that you can distinguish which type of CDN you need.

Types of CDN: Push CDN and Push CDN
Types of CDN

1. Push CDN

As the name says, a Push CDN allows you to push your content into the new server. So, you’ve to manually copy the information from your site from the origin server to the PoPs.

This seems to be a bit more work. However, the process can be worth it for some site owners. Because you’ll have full control over a lot of options. That includes what, when, who, and where the content delivery goes.

2. Pull CDN

On the other hand, a Pull CDN automatically pulls the site content from your origin server. So, you don’t need to upload anything by yourself. The server will pull the content whenever someone requests access. And the CDN will transmit it to them accordingly.

As a result, this reduces the extra work for you. However, it also takes away a lot of your decision-making options in the process. Since you need to work with the pre-configured settings of the service.

Which CDN Type is Better for You?

We came across 2 CDN types. But you may be wondering which one’s perfect for you. Let’s see!

If you have a large site with high traffic, then you can choose a Pull CDN. Because it comes with regular automatic refreshes to deliver your content.

Whereas for newcomers with a smaller low-traffic site, you can try using Push CDN. Since you won’t need to refresh the content often. You can just upload the content and keep it for some time.

By saying that, let’s move into our main topic of interest!

Do You Need a CDN? (Top 9 CDN Benefits Explained)

Many top brands and sites today are using CDN services. As per BuiltWith, over 62% of the top 10K sites globally use a CDN. 

However, the percentage reduces when we look at the top 1M sites. This shows that many smaller businesses don’t realize the merits of using CDN.

So, what are these advantages that a CDN provides? Here, we’ve explained the top 9 CDN benefits. Go through each of them, and you’ll know if you need a CDN service for your site or not.

1. Improves Your Site Speed

The primary function of CDN is to reduce network latency. In simpler terms, it aims to make the content reach the visitors as soon as the request is sent.

When a user requests a site content, the browser fetches the cached content from the closest CDN server. So, visitors won’t have to wait for the request to go to the origin server. This highly reduces the load time of the site.

Improves Your Website Speed

Note that a CDN is best for businesses that rely on their sites to transmit content faster. 

For example, online shops aim to quickly convert shoppers into customers to grow sales. And some delays in the page load time can lead to the loss of those potential customers. 

Because of that, a business must use a CDN to deliver its site content quickly. Thus, if your business relies on your site to deliver content faster, then you need to use a CDN.

2. Helps Your Site to Reach Globally

As per the latest report by Statista, there were 4.9 billion internet users worldwide in 2021. This increasing number of internet users also brings a new opportunity for your business. However, you need to explore your market and deliver your service effectively and efficiently to succeed.

But how can users all around the globe reach your site smoothly with a single origin server? That’s when CDN comes into play. By using a CDN, your site can reach everyone globally. Ultimately, it also helps to boost your business.

Helps Your SIte Reach Globally

That’s because a CDN service provides PoPs across the world, making your site available in every part of the globe. So, your business can now reach the new untouched market easily.

Suppose your business targets users from some particular locations. Then, you should check the coverage map of the CDN providers. Accordingly, you can choose the service that gives the best benefits to reach many users of your target location.

For example, Sucuri CDN contains multiple PoPs of various types. When it comes to CDN Edge, they are present in 2 different locations, Sao Paulo and Sydney.

3. Makes Your Site Secure

Another benefit of CDN is that it makes your site secure. 

About 60% of users visit a website and access the content via a CDN, so it becomes important to maintain security. For that, it comes with a range of features for additional protection.

Now, let’s look at those features that most CDN providers offer:

i) SSL Security

Some CDNs offer pre-configured SSL (Secure Socket Layer) security. This ensures everything is encrypted between the edge servers and the origin server. The reason behind it is to also gain the trust of your users.

SSL Certificate

ii) Secure Token

There are CDNs that give a secure token to generate secured links with expiration time. So, after the token expires, users can no longer access the content.

iii) Web Application Firewall (WAF)

Lastly, most CDNs have a WAF that filters, monitors, and blocks HTTP traffic. It means it can also prevent and protect against cybercrime activities. Such as data breaches, DDoS (Distributed Denial of Service) attacks, and man-in-the-middle attacks.

Here, protection against DDoS attacks is the most crucial thing for CDNs. For those who don’t know, a DDoS attack is when an attacker sends a large volume of requests. This overwhelms an important DNS server resulting in server downtime.

But for DDoS protection and mitigation, CDNs distribute the load equally to the entire network. So that the attack can’t reach the origin server while the website also keeps running.

If you want to secure your site, then CDN can help you with that. Apart from that, there are other ways for site security. To know them, here’s our complete guide on how to secure a website.

4. Delivers Uptime Service and Content Availability

When there’s a sudden traffic spike on a site, its server may crash, leading to downtime. Similarly, network congestion and connection interruption can lead to inconsistent content availability.

Example of Web Hosting
Server Downtime

To avoid such circumstances, using a CDN is the best option. That’s because CDNs balance the load of network traffic. So that servers won’t get overwhelmed even in heavy traffic, and there are fewer chances of the server crash. As a result, multiple users can access the content simultaneously.

But how does a CDN do that? In simpler terms, a CDN comprises several PoPs spread across multiple data centers. This reduces the strain on the origin server.

On top of that, when a server gets overloaded, other servers can still deliver your content in the network. Thus, this redundancy helps in providing uptime service and content availability.

Delivers Uptime Service and Content Availability

But suppose a server ultimately stops working. Then, at that moment, CDNs initiate the failover function and make the backup server take over instead. Cool, isn’t it?

5. Strengthens User Experience

User experience is a crucial factor in boosting your site’s conversion rate. And the best way to satisfy visitors is by improving the site speed.

According to Google, more than half of mobile users leave a site when it takes over 3 seconds to load. This shows how important it is to maintain a good site speed to develop user satisfaction.

And we already know how a CDN improves the page load time of a site. 

In the same way, a CDN also strengthens the user experience because of the quick page load speed. Overall, it helps to grow your business due to the increasing number of satisfied customers.

6. Lowers the Bandwidth Usage and Cost

For newcomers, bandwidth is the data flow rate between your site and visitors. And every hosting platform has a bandwidth amount set.

What is Bandwidth in Web Hosting?
Lowers Bandwidth Usage and Cost

Suppose your site suddenly gains a lot more visitors. Then, this can exceed the bandwidth limit of your site. As a result, your site may not be available for users until you increase your bandwidth or pay an extra fee.

A solution to highly reduce the amount of bandwidth usage for your site is by using a CDN. 

CDNs cache and optimize the static content of your site. Then, store them in multiple PoPs. So, the data transfer rate on the origin server will lower ultimately.

Therefore, CDNs help reduce bandwidth demands on origin servers. Moreover, it also lowers the web hosting cost since you won’t have to pay for extra bandwidth.

7. Reduces Your Expenses

Now, we know that CDN reduces the cost of bandwidth usage of your site. But that’s not the only way it lowers your expenses.

Reduces Your Expenses

There are some other reasons why a CDN helps you save money. So, let’s check those benefits:

  • Security: CDN protects your site from common cyberattacks. This indirectly saves the unwanted expenses that server outages and compromised websites may cause.
  • Foreign Hosting: A CDN eliminates the cost of using foreign hosting to reach a global audience. Since a CDN has servers spread wide across the different regions of the world.
  • Separate Service: Using a CDN, you can handle all the separate operations of different PoP locations. That too with a single platform at a reasonable price.

8. Provides Valuable Data and Analytics

Another benefit of CDN that you may not know is the valuable insights they offer. 

Today, CDNs are responsible for serving over half of the world’s internet traffic. So, they can collect a vast amount of data on users. Such as internet connectivity, device usage, etc.

Using these valuable data, you’ll get helpful user analytics like capacity per customer, most active areas, etc. With that, you can now understand the trends and content consumption patterns.

A website that loads fast isn’t only what users love. But search engines too.

Relevancy may be the main criteria for search engine rankings. But after that, page load speed and user experience are the top factors that decide your site ranking.
