In my last blog I talked about AWS S3 integration with WordPress. Moving forward on similar lines, In this blog I will explain how AWS CloudFront can be setup for caching WordPress media files.

AWS CloudFront is a content delivery network(CDN). It is integrated with various amazon web services like AWS S3. It act as caching engine for media files like images, css, js, videos etc. It distributes content to end users with low latency and high data transfer speeds.

Great! you are done with AWS cloudfront WordPress integration with your blog. Let’s test it.

Testing AWS CloudFront WordPress integration

  • Open any featured Image url from your blog list.
  • Now access the same Image url with CloudFront domain name prefixed with http://*
  • Accessing for the first is little delayed for 1-2 seconds.
  • If accessing image using CloudFront domain works perfectly, your WordPress integration is complete.
  • I made a mistake of using distribution id in CloudFront url instead of CloudFront domain name. Obviously it didn’t work.

Setup Sub Domain for Images with AWS CloudFront

Using Amazon CloudFront for your wordpress website has various advantages except CDN caching:

  • It boosts page load time.
  • Lowers the bandwidth of the server.
  • Consistent distribution across different regions.

Amazon CloudFront gives ugly looking sub domain url for accessing the files. Using sub domain(of your website) for images looks more professional. e.g. is much more intuitive than *

Even Amazon also uses sub domain( for accessing images. You can verify url of any image on Amazon website.

  •  You will need to update Amazon CloudFront distribution settings after login to account. You can configure multiple alias alternate domains.

Premature optimization is bad. Use AWS CloudFront in your WordPress blog when your  website has huge traffic and media files are loading slowly. CDN is not of a much use for low traffic websites. If you are interested in AWS big data services, I recommend reading below articles:
