Why we use Cloudflare

back to blog

What is Cloudflare?

Cloudflare is essentially a Content Delivery Network (CDN).  The core function of Cloudflare is to help small to large businesses secure their online assets and make them faster.  It was set up in 2009 with the original aim of finding the source of email spam and eliminating it.  Over the years it has evolved and now provides DNS and security services to millions of customers. Today, it is one of the largest cloud network platforms and is trusted by over 12 million domains.  Furthermore, it handles around 10% of all internet traffic. We look at how it works and the main benefits of using Cloudflare for your business.

How does it work?

CDNs provide a global network of edge servers.  For sites that serve customers around the world, the network allows the content to be served up much quicker.  If a user visits the site, but is located in another country or even continent from the server then they will experience slow page load times.  With a CDN, the request is directed to the nearest possible server speeding up the content.  Ensuring the least amount of distance between a visitor and a website results in reduced latency, bandwidth and page load times.  Essentially, this means that Cloudflare-powered websites can work faster while remaining secure. 

Similarly, Cloudflare also provide DNS (Domain Name Server).  DNS is the phonebook of the Internet, it translates a domain name such as wirebox.co.uk to an IP of the server.  This means the browser can download the site quicker.  Having a CDN in front of your website will also mean it can process large volumes of traffic, reducing the risk of the website crashing at peak or high traffic times.

5 Benefits of using Cloudflare

  1. Faster DNS  With a faster DNS, implementing Cloudflare is an easy way to speed up your site.  Speed has long been considered a ranking factor for Google’s algorithm so a faster site will help with search rankings and SEO.  It will also mean that users are being served content quickly from wherever they are in the world.  
  1. Minification  Characters such as whitespaces, comments, newline characters and block delimiters are not needed for a web page to serve.  By eliminating these unnecessary characters, the file size is reduced allowing the page to load faster.  Cloudflare supports three file types of minification: Javascript, CSS and HTML.
  1. Free SSL  Cloudflare offer free SSL’s, which are recommended for all websites.  SSL’s encrypt data from the user’s computer to your server. This is essential on sites that send or receive data or take payments.  In addition, Google announced that they would flag sites without HTTPS as “not secure.”
  1. Browser Caching  By storing web page files, browser caching  further increases page load times for repeat site visitors as requests are loaded from the local cache.  Cloudflare can handle this with the need for any other third party cache plugins.
  1. Enhanced Security  Cloudflare’s security features are highly regarded and will protect your site.  It will automatically block threats such as data breaches, bot attacks and DDoS (distributed denial-of-service) attacks.  As well as providing high level security, this will ensure that disruption and downtime to your site are minimised.
