Content delivery network a.k.a CDN is one of the name which you will always hear when ever someone is talking about speeding up your site. CDN has become one of the easiest way to make your site load faster. Infact all speed checking tool like gtmetrix, Google page speed suggest to use a good content delivery network to improve the site performance. People with technical background are aware of what is CDN and benefits of using content delivery network, but for non-technical people, it sounds like some alien word. Well, nothing to worry about as in this blog post I will be talking in depth about content delivery Network and why you should be using one.
What is CDN a.k.a Content delivery network
Let me start with Layman language. We usually use shared hosting and all our files are hosted at one data center. For example, mine is hosted at Knownhost and I’m using Texas data center. Now, when a user open ShoutMeLoud.com, his request goes to my data center at Texas and that’s how files and thus my sites loads on his browser. Sound simple! But this leads to high ping and latency and thus it takes time for site to load, depending upon location of user.
Now, a content delivery network have data center at different geographical location and when your site is using a CDN network, and a reader opens your site, your files (Images, static files) are served from the nearest data center of CDN network you are using. This reduces the ping, latency and thus your site serves faster. This is first and prime benefit of using a CDN.
In other word, they uses a technique call content replication, where your content is copied on different servers located on different region. A Good CDN service will have multiple servers on different locations. When you are serving your WordPress or any other Website file using a content delivery Network, you are technically saving time of your readers and reducing the server load, as files will be served from other servers and not your hosting company.
When you configure a CDN, you uses the pull or push technique to upload your existing files to server, we will talk about this in my next article on how you can configure CDN for your site. As we say, images speaks thousand words, here is a self-explanatory image from MAXCDN, which explain how it works:
Benefits of using CDN:
