CDN, otherwise known as Content Delivery Network, is incredibly simple software despite coming across as convoluted and complicated to get to grips with. It is somewhat of a silent assassin, working behind the scenes to make our online lives easier.

In fact, most internet users probably rely on a CDN services daily without even knowing that they are using it, let alone what it does and how it works. Don’t worry if this is all new to you – by the end of this article, you will know everything there is to know about CDN’s.

Let’s get started!

So, if you didn’t already know, the web is a pretty big place. However, the size of the internet is kind of in its name – the world wide web.

In fact, software like CDN’s makes this ‘stretching’ process possible. It stretches across all of the far reaches of the world. It is actually more significant than any of us could comprehend. We live in a global society, whereby with the correct flight ticket we can travel to any country we want.

Nowadays, nowhere is off-limits, and the same goes for the internet. If you were limited to only visiting websites made and based in your native country, the scope of your search would be drastically limited.

Let’s say you are based in the UK, but you want to access an Australian website. You wouldn’t expect the server load time to be any different despite the vast geographical distance, simply because it is an Australian website, would you?

That is because CDN’s are so good at doing their job. They increase the connection speed between your server and that Australian site by decreasing the distance.

But how? Great question…

How Does a CDN Work?

The internet may be innovative, but it isn’t intelligent enough for time travel and space bending. So how can it possibly decrease the distance between your UK server and Australian site?

The answer is surprisingly much more straightforward than you would think. Let’s compare CDNs to oriental supermarkets. Let’s say you are dying for an authentic Pad Thai, but you can’t find all of the ingredients in your local supermarket.

You wouldn’t hop onto Skyscanner and book the next flight to Bangkok, all in the name of fish sauce! No, you would simply take a trip to your nearest oriental supermarket and find the ingredients there.

Well, CDN’s work in a similar way. CDN’s connect with PoPs (Points of Presence), which are essentially servers dotted around the world. These PoP’s would be responsible for storing a version of the Australian website you were searching for. Meaning the data is closer and more accessible to you, meaning a quicker load time.

CDN services are responsible for connecting you to these PoPs, acting as the middleman between your server and the site you seek. So, where an oriental supermarket stores a version of the ingredients you desire for your Pad Thai in your local area, CDN’s store a version of the foreign website in PoPs. This connects you to the closest PoP when searching for the foreign site.

However, it is essential to note that CDN’s generally only store static content, like images, documents and JavaScript. The best way to understand this is to relate it to the oriental supermarket once again.

Sure, the supermarket can store static objects from Thailand, such as dried noodles, spices, and curry paste. However, just because these products originate in Thailand, you wouldn’t expect to find Bangkok’s floating markets or the famous Emerald Buddha Temple in the oriental store.

The same goes for CDN’s and dynamic websites (essentially websites where the user and site interact). Therefore, while CDN’s can speed up the connection speed between your server and foreign web content, they can’t always be relied on to deliver you dynamic content.

You win some, you lose some.

The Importance of Website Speed Optimisation

While the web world is pretty confusing to most newbies, one underlying notion remains consistent in all tech areas; if you want your website/software to succeed, it needs to be fast.

Over the past decade, the speed and sophistication of the internet have advanced at such an exponential rate that internet users now expect lightning-fast speed and nothing less.

Gone are the days of dial-up, waiting around for 5 minutes simply to load one page. Unfortunately, the modern attention span is short, so your website page speed simply has to accommodate.

Picture this; you want to buy a new kettle. You type ‘kettle for sale’ into your search bar, and hundreds of pages show up instantly. You click on the top one and are left waiting for, let’s say, 7 seconds. It may sound like nothing, but in reality, we are so used to web pages that load in under 1 second that I would be surprised if your patience even lasted past 3 seconds.

With hundreds of other pages selling kettles available to you, a simple back-click and you are on a fast-loading page. Furthermore, you won’t be the only person to give up on waiting on that first website that day, meaning its bounce rates will dramatically increase, lowering its ratings.

Not good at all.

So, website speed is essential – but how does this relate to CDN’s? As previously mentioned, the aim of CDN’s is to improve the load speed of geographically dispersed web pages.

This means that, especially if you expect your website to receive a lot of traffic from users in other countries, a CDN will dramatically improve your website’s load time. Improving its overall performance and popularity.

CDN’s improve the load time by storing your site’s data onto a global database in a cached format. When a user requests said data, it is ready and waiting for them.

Benefits of Using a Content Delivery Network

Are you sold on CDN’s yet?

Not quite?

That’s okay – it’s good to get a complete picture of the product you are considering investing in.

We have already touched on how CDN’s can improve your website’s load time, an improvement that will go a long way in propelling your website ahead of its competition.

However, the benefits of using CDN’s does not end there. They have a fair few tricks up their sleeve, sure to intrigue even the most sceptical web user.

Improved User Experience and Site Performance

One of these tantalising tricks is that using a CDN can actually reduce your costs by removing the need for you to access foreign servers. Furthermore, they can help with bandwidth costs and allocation, freeing up your site’s available bandwidth to allow for more traffic and, you guessed it, faster load times.

The great thing about a website having more available bandwidth is that it has a more robust uptime rating.

Uptime refers to the amount of time a website is live and available to take online traffic – pretty necessary, as it essentially does not exist when a website is down. This effectively means that, with more space to host multiple users at once, there is a much lower chance of the website crashing, leading to a low uptime, which can be devastating for a website’s ratings.

Therefore, in addition to increasing the loading speed of your site, increasing the available bandwidth for your site and decreasing your site’s costs, CDNs can improve your site’s uptime, arguably one of the most important things to cultivate in order to ensure your website is a success.

Better Security and Availabilty

And if that isn’t enough to sell you on CDN’s, they can also enhance your site’s security. This is because CDN’s are the first port of call in a web interaction between user and server. Therefore they are often the first software to detect potential cyber-attacks and viruses.

CDN’s can trigger two primary lines of defence against potential attacks; Common Exploit Scanning and Automated Attack Identification. Furthermore, CDN’s work like traffic wardens, dispersing online traffic to avoid a damaging DDoS attack (denial of service), which attempts to flood your site with traffic.

Choosing a CDN for Your Website

They may say that the best things in life come for free, but there are definite exceptions to this rule. A considerable amount of the online world is now free; therefore, it can sting to part with hard-earned money for online investments.

However, sometimes paying for software is precisely that; an investment. Furthermore, there are often different price plans offered on software such as CDN’s, tailored to the various needs of different web users.

Suppose you have a small website that you use as an online portfolio for your work. In that case, things like bandwidth, security and website speed are going to be a lot less important to you than, let’s say, a large-scale online shop.

Companies tend to reflect this in their pricing, so there may even be some free options out there for you.

Let’s take a closer look at the 10 most significant players in the game…

The Top Content Delivery Networks for 2022

#1. StackPath

stackpath landing page

StackPath offers a free 30-day trial, with prices after this starting at £7.69 per month for the basic plan, giving you 1TB of bandwidth, origin shield and DDoS protection.

The more advanced plan comes in at £15.38 per month, along with the added features including unlimited EdgeRules, managed DNS and StackPath’s Web Application Firewall.

However, StackPath is limited to operating solely in the US and Europe (apart from a few exceptions) and, unfortunately, does not have the best track record for performance.

#2. Fastly

fastly landing page

You can try Fastly for free, and they provide everything you will need to get started. Once you’ve completed your trial, they charge a minimum of $50 per month (roughly £35.41), depending on your usage.

Their basic package comes with 3TB global delivery per month, 30mm Image Optimiser images per month, and you can secure up to 10 domains using their non-profit CA/BYO certificates.

Their top-end package has unlimited global delivery, customer image optimiser, and TLS. Fastly is used by huge companies such as Amazon, The Guardian and even the UK government.

#3. Akamai

akaami landing page

Akamai is pretty renowned in the CDN world, covering around 30% of the world’s web traffic. Pretty impressive. They have an excellent performance reputation and loads of attractive added features.

However, there are a few issues associated with Akamai’s advanced service. For example, it can be a reasonably complicated service to set up. Furthermore, their pricing is pretty vague, and it seems that you need to contact the company directly to find out more about their pricing.

Essentially, if you are a web pro, Akamai is a good shout for you. If not, maybe stick to a more uncomplicated service.

#4. Sucuri

sucuri landing page

Sucuri is mainly an internet security company that offers CDN as part of its security package. They charge annually, and while they don’t have a free trial, they do have a 30-day money-back guarantee.

Their basic plan is $199.99 (£144.76 approx.) per site per year. This gives you CDN performance, malware and hack scans every 12 hours, malware removal and hack cleanup, amongst other things.

Their most popular package is Pro at $299.99 (£217.20), which gives you scans every 6 hours plus added SSL certification. The Business package is $499.99 (£362.01), scans every 30 minutes and removes malware every 6 hours.

#5. Bunny.net

bunny.net landing page

Bunny.net gives you a 14-day free trial to test out its capabilities. It has two pricing plans, with the standard being $0.01 per GB (which is less than a penny) and one for high bandwidth projects at $0.005/GB for the first 500TB, $0.004/GB from 500TB-1PB, $0.003/GB from 1PB-2PM and $0.0025/GB from 2PB+.

Bunny.net offers streaming, edge storage and optimisation. It takes no time to set up and is the best WordPress CDN on the market. This plug-in has excellent reviews as it’s very user-friendly and affordable.

#6. Cloudflare

cloudflare landing page

Offering a totally free plan, Cloudflare is your best bet if you are just starting out with a small website. However, this free plan is extremely basic, covering only 3 online pages and having somewhat limited security features, offering only DDoS protection.

You can upgrade to Cloudflare Pro (£16 per month) and Cloudflare Business (£160 per month) for added features such as the capacity to cover 20-50 web pages, image optimisation, SSL Certification and PCI Compliance. Great features, however, at quite a cost.

#7. KeyCDN

keyCDN landing page

KeyCDN’s prices are advertised as low and remain low, even on the most advanced plan. Interestingly, they charge based on the amount of bandwidth your website requires, with prices starting at £0.03 per gigabyte of data.

Furthermore, they offer a 30-day free trial, with an alluring 25GB of data to play with, so that you can test out the software before committing to it.

However, if you want to continue using KeyCDN after this trial, you have to pay £39 upfront, which sounds like a dramatic jump-up. Despite this, £39 will give you full access to all their features at a much lower cost than Cloudflare.

#8. Imperva

imperva landing page

Imperva is another internet security company covering data and application security and CDN’s. They offer load balancing, failover and content caching built into a comprehensive WAPP.

They provide a free plan that gives you bot mitigation, CDN and two-factor authentication. Their paid plans are $59 (around £42.72) per site monthly for the Pro plan, which adds a web app firewall, advanced performance PCI compliance reports, backdoor protection and SSL support to the basic feature.

The Business plan is $299 (£216.49) per site monthly and includes all the Pro features plus protections from DDoS attacks in the network and application layers and auto-detection and triggering.

#9. Rackspace

rackspace landing page

Rackspace charges based on traffic use and requests. There start at $0.10 (about 7p) per GB for the first 10TB, which drops to $0.02 (just over 1p) for traffic above 5PB. They also offer $100 of free credit to start you off.

They do charge for requests too, but a million requests are only around 60p, so it won’t break the bank. They don’t use their own servers, instead using Akamai, one of the biggest CDN providers around and have been found to be faster than most in independent testing.

So the plus is that you get access to Akamai’s fast CDN network. Still, the downside is that some users have found that the limited features available aren’t worth the price tag.

#10. Amazon Cloudfront

amazon aws cloudfront landing page

Amazingly, Amazon CloudFront have a Free Usage Tier, allowing customers 50GB of traffic per month for a whole year. Wow.

From this point onwards, and for more advanced features, Amazon web services charges around £0.65 per gigabyte of data delivered, with a few other additional costs thrown in, such as technical support and data requests. Admittedly, the pricing is pretty confusing. With its pay-as-you-go mentality, it can be easy for costs to add up quickly.

Despite this, the performance is strong, and you can’t go far wrong with a free plan which lasts for a whole year.

Best Content Delivery Networks for 2022 in Summary

So, after all of that, the question is whether a CDN is suitable for your website or not. Ultimately, we would suggest that if you’re only just starting out in the web world, with a small website which you don’t expect to hold much traffic, then maybe you don’t need a CDN.

Here’s a quick recap of the Best Content Delivery Networks in this guide:

  1. StackPath
  2. Fastly
  3. Akamai
  4. Sucuri
  5. Bunny.net
  6. Cloudflare
  7. KeyCDN
  8. Imperva
  9. Rackspace
  10. Amazon CloudFront

It’s always an excellent addition to a website, so perhaps try out a couple of free plans to see if they suit you and if not, at least you tested the waters. It’s also good to note that most web hosting providers offer CDN’s for free in some of their hosting plans.

Conversely, suppose your website has a high level of web traffic, especially traffic from foreign countries. In that case, you’d be a fool not to invest in a CDN. It will dramatically increase your website’s speed, performance and overall ratings, even if these changes come at a small monetary cost.
