8 benefits of Content Delivery Network (CDN)

Introduction

CDN services enable the rapid distribution of assets such as javascript code, HTML pages, stylesheets, pictures, and videos which form a part of today’s rich Internet content. CDN solutions are becoming increasingly popular, and they now handle the bulk of web traffic, including traffic from large sites like Netflix, Facebook, and Amazon.

Some CDNs also help to protect websites from malicious attacks, including Distributed Denial of Service (DDoS).

A CDN doesn't host material and cannot replace the requirement for proper web hosting, but it can aid in the caching of content at the network edge, improving the website's performance. Many websites find that standard hosting services fail to meet their performance requirements, and that is why they turn to CDN services. Content delivery network services are a popular solution for relieving some of the primary pain points associated with conventional web hosting by leveraging caching to minimise hosting capacity, assist in preventing service outages, and improve security.

What can CDN services do to enhance the user experience?

Customers' experiences on your website may make or break your business, and it's becoming increasingly important. According to Google's research, 53% of mobile consumers abandon a site that takes more than three seconds for loading. Furthermore, 79% of customers said they would not revisit a website that performed poorly.

With such a strong reaction to a bad website user experience, any business with an internet presence must have a high-performing website that provides a great user experience. Incorporating the utilisation of content delivery network services in your website is a terrific alternative for businesses trying to achieve web-based peace of mind. Your website's load speeds will significantly improve, and potential clients will not be left waiting and feeling restless if you use CDN solutions.

According to the sources A site that uses content delivery services will load a minimum of 30% faster than one that uses a traditional server-based solution on average. Based on the sort of website being loaded, this might mean cutting seconds off the time it takes for your site to load.

Even better, these outcomes will assist you in the long run regarding Google. To rank pages in the Google SERP, Google has enhanced the importance of site performance and overall user experience.

8 benefits of CDN

Decrease latency

When it concerns websites loading content, visitors leave quickly if the site takes too long to load. CDN services may aid in load time reduction in the below-mentioned ways:

• Because a CDN is globally dispersed, it reduces the distance between the website resources and the users. Instead of connecting to the origin website server, a CDN allows the user to connect to a data centre that is closer to them. Faster service means less travel time.
• Faster data delivery can be aided by hardware & system enhancements like better load balancing as well as solid-state hard drives.
• By lowering file sizes with techniques like compression and minification, CDN solutions can decrease the quantity of data delivered. Smaller file sizes take less time to load.
• By minimising connection reuse and permitting TLS false start, CDNs can help speed up sites that use TLS/SSL certificates.

Ensure maximum availability

The CDN's servers are always up and running, so your website is available even if the server is offline. Your server may go down without a CDN, meaning you'll have to wait while your host resolves the issue. If you're utilising a CDN, this won't happen. The CDN services will be using your cached web pages in the event of a server crash.

Reduce server load

A CDN placed strategically can reduce server strain on private and public peers, interconnects, and backbones, thus freeing up capacity and lowering delivery costs. Instead of unloading the content into a single huge server, the content is divided across several small servers.

Enable global reach with local PoPs

Over a third of the global population is online, implying that internet usage has grown exponentially during the last 15 years. Due to its global reach, any latency issues that disrupt long-distance digital transactions and create poor load times will be eliminated.

Provide DDoS protection

DDoS assaults can have a significant influence on the image and reputation of the affected firm or organisation, in addition to causing significant financial losses. Customers place their faith in a company when they key in their credit card details to make an online transaction. 

An assault can be stopped before reaching your data centre. A CDN efficiently handles the traffic, which will keep your website up and operating. It means you won't have to worry about DDoS attacks affecting your data centre, ensuring the security of your company's website.

More simultaneous users

High network backbone bandwidth can be achieved by strategically putting servers in a CDN, resulting in a considerable spike in the number of users using the network at any given moment. For example, a 100 GB/s network backbone with a capacity of 2 TB/s can only supply 100 GB/s. However, with CDN services, ten servers would be available in ten key places, with an overall capacity of ten x 100 GB/s.

Flexible control over asset delivery

If a server in a particular region is overburdened, operators can supply additional bandwidth to ensure that everything runs properly.

Reduce bandwidth cost

Bandwidth charges can build up quickly for a website, primarily if it hosts a site with a lot of rich media. As SMBs continue to hunt for ways to help their brand stand out from all the competition, this presents an uneasy trade-off. This usually entails using large materials like high-resolution video and photos, as well as specialised coding.

Content delivery network services can lower the quantity of data that the hosting provider needs to provide by caching at the network edge. In most situations, this reduces hosting expenses for small businesses, freeing up resources for other projects.

Invest in the best content delivery network services

It will pay off if you've had a popular website with a lot of traffic and just enough resources. You will receive a speedier website and an added security layer in exchange for the payment.
