What is a Content Delivery Network and How It Works For Singapore Websites

What Is A Content Delivery Network And How It Works For Singapore Websites

Content Delivery Network, commonly shortened as CDN, is a system of networked servers that are synchronized to deliver web pages and content to individual users based on the nearest web server.

The system is designed to take one’s web content and distribute them across different web servers, doled out in different geographical locations for easy accessibility and speedy conveyance.

The content requested is often pulled from the closest web server. For instance, if you happen to be browsing the site from Singapore, the content requested will be fetched from a CDN server in Singapore. If another user is browsing the same web page in, say, London, the content will instead be pulled from a Content delivery network server in London instead of Singapore. Therefore, it will increase your site speed and improve your content marketing strategies in Singapore.

Designed to permit a speedy transfer of the files needed to load up a site, including machine-readable HTML pages, style sheets, JavaScript files, videos and images to name a few. The concept itself is NOT new. As a matter of fact, the network serves the majority of web traffic as it stands.

To determine which server is closest to an end-user, the network utilizes content delivery network mapping technology, which is basically an algorithm that scans all web servers within the network in a matter of microseconds to pull out the closest.

What happens is that web owners and companies pay content delivery network operators to deliver their web content to individual users in the fastest way possible. CDNs will pay ISPs and network carriers to host their servers in their respective data centres.

So basically, CDN is an all-encompassing term for the different types of content delivery services in the gamut of video streaming, mobile content acceleration, software downloads, transparent caching, and a series of other services for measuring CDN performance, Multi-CDN switching, load balancing, cloud intelligence, and analytics to name a few.

At some point, CDN vendors may decide to cross over into an array of other industries including WAN optimization and security.

Content Delivery Network in Layman’s Language

In simpler terms, CDN replicates web content to distribute it across a number of servers for easy and speedy retrieval upon request. This way, when a user searches for a piece of content on the network, the system scans through the various servers to deliver the content from the nearest one. The algorithm running the process does everything at a lightning speed, thus lowering the latency and giving your site a wide exposure, spanning a wider geographical location.

Cloud Content Delivery Network Benefits

CDNs come with tons of benefits for users and web owners.

Content Delivery Network

Improving Web Security

CDNs can help improve your web security by making necessary improvements to security certificates, providing DDoS Mitigation, and optimizing your security settings.


Clients pay for bandwidth. Meaning they pay for the capacity they utilize thus avoiding unnecessary costs like paying for unutilised capacity.

CDNs can also reduce the amount of data loaded through caching, thus significantly reducing your hosting charges.

Nil Investment

No upfront investment on infrastructure. All the required purchases and maintenance costs will therefore be carried out by the ISP.

Faster Internet Access

The system works by bringing content closer to visitors, thus ensuring faster and more efficient delivery. The network is designed to reduce latency, increase performance and avoid traffic congestion.

New Markets

Your visitors are NOT restricted to one place. Regardless of where the visitor is, the network can pull content from the nearest server to deliver it. That way, web owners are given the opportunity of exposing their content to new markets, some of which could be way out of their reach were it NOT for CDN.


CDN allows you to handle fluctuating traffic. With the network, you don’t have to worry about your web traffic overstretching your server resources as with shared hosting or VPS. Designed to scale your web resources up and down depending on the amount of traffic you’re driving, the content delivery network can handle almost any amount of traffic with little to zero downtime.

How CDN Works in Real-time

The transfer of files will take more time if a Singapore user sends a request to a server located in the UK or the US. However, with a CDN POP, the system can easily cache the web files and distribute them to different servers across the world. Meaning when the Singapore user requests for a web page, the files will be pulled from a Singapore CDN server instead of the US or UK server as it’s always been the case, thus reducing latency.

The Concept of CDN is NOT new and can enhance your Singapore local SEO efforts. If anything web owners have been using it to boost the performance of their websites since the 90s. The difference is that it was only available to the big wheels with a war chest of cash in venture capital.

The definition of CDN has however changed a great deal over the years. It has also revolutionized the digital landscape by making content delivery more efficient and cheaper, in addition to accommodating any website out there however small it is.

Besides latency (the amount of time it takes for your request to get a response from a web server), CDN can also help to improve your throughput. Let say, for instance, some user somewhere streams for a video online, waiting for an extra 200ms for the video to start loading can be devastating in a way.

It’s much more crucial that the video streams at a much-sustained speed of, say, 3 Mbit/s.

Now try comparing an old fileserver to a CDN – besides improving your latency by bringing your web content closer to the end-user, CDNs will also be working to improve your throughput.

For file servers, there’s the expected risk of your site chocking up really quickly with multiple users streaming it simultaneously, and the only way to allay the effect is to have multiple file servers to handle the task at hand. But since file servers operate from one location, you’re bound to suffer the risk of network congestion during the transfer of files from a webserver to the end-user.

CDN relieves you of the burden of scaling down your web servers where files delivery is concerned. More of your data can be delivered to the end-user and at a much faster rate than a file server, considering all your web content will be cached and globally distributed for easy accessibility and speedy conveyance.

Using CDN to Make Your WordPress Site Load Faster

Google nowadays considers load time as one of the biggest ranking factors for their result pages. To secure a favorable spot on the SERPs, it’s advisable that you keep your load time under 2 seconds.

This is NOT easy as there’s a lot to be done, including picking a best-performing hosting service for your site. If your website is loading like terrapin, then odds are – every single one of your competitors with better load time will most likely displace you in the search engines.

There’s also a fair chance your site will completely disappear from the search engine.

Simple logic dictates that you choose the best hosting provider or, better, CDN. For WordPress, you’ll also need a good caching plugin and overall site optimization for speedy load time.
