Top CDN Providers for Your WordPress Website

If you are ready to take the next major step in speeding up your website, now is the time to consider signing up for a content delivery network, otherwise known as a CDN.

Dramatically reducing server lag by storing your website’s static resources on a network of heavy-duty servers strategically located across the globe, a CDN can ensure a faster service response to your readers and reduce the download time of your site’s content.

Today we will look at why you might want to employ a CDN provider to your growing website, as well as evaluate some of the major players in CDN services.

What is a Content Delivery Network (CDN)?

A CDN is a network of servers scattered around the world that cache your website’s static content such as images, CSS, and JavaScript files and deliver them to your readers when they access your site.

After a visitor clicks on your website, the majority of page load time spent is waiting for the server to retrieve your content and deliver it to their computer in a readable format. If you simply have a hosting service, whether shared or managed, no matter where in the world geographically your visitor is stationed, your content must be retrieved from a single server located either near or very far away.

If located far away, say continents away, your website’s content will take much longer to be retrieved and delivered to your user’s computer.

However, as you can see in the picture above, using a CDN significantly decreases the distance your cached content must travel to reach your visitor. And the great thing is, CDNs have multiple servers placed all over the world so whichever is closest to your user is the one that retrieves and delivers the content. That means super-fast loading time.

Using a CDN not only increases the speed of your website, it also provides crash resistance due to large spikes in site traffic, improves user experience, and helps rank you well in SERPs due to the optimization of your website.

Now that you have a basic understanding of how a CDN works and why it might be beneficial to use one, let’s take a look at some of the most popular CDN providers.

Top CDN Providers for Your WordPress Website

Amazon Web Services (AWS) offers multiple cloud-based solutions to help you meet your website’s needs. Owning and maintaining the network-connected hardware necessary for their services, AWS creates a simple way for you to have access to servers, storage, databases, and internet application services.

Using the AWS Free Tier Service (available with all CDN plans) you have the chance to try AWS Cloud Services for one year for free, though depending on the plan you associate the free tier with there are certain usage limits.

Here is a look at two of the most popular CDN services available:

  • Amazon S3 – Easy to use and with a simple web service interface to store and retrieve any amount of data from anywhere on the web, Amazon S3 is designed with developers in mind as a storage solution. As part of the AWS Free Tier Service, receive 5 GB of standard storage, 20,000 get requests, 2,000 put requests and 15GB of data transfer out each month free for one year. There are also 3 levels of storage classes based on the frequency your objects are accessed and length of time your storage objects need archiving.
  • Amazon CloudFront – Integrating with other AWS products, Amazon CloudFront give developers an easy way to distribute content with low latency, high data transfer speeds, and no minimum usage commitments. Deliver all dynamic, static, streaming, and interactive content using a global network of edge locations. As part of the AWS Free Tier Service receive 50 GB data transfer out and 2,000,000 HTTP and HTTPS Requests each month for one year for free.

All AWS products allow you to pay only what you consume, access only what you want to, and scale up and down however you see fit. It is however, a very large company offering complex products and is mostly geared toward experienced developers. Those with smaller websites and no developer background will quickly find the services provided overwhelming and confusing.
