Amazon CloudFront

From Showit Desktop Manual

(Redirected from CloudFront)

Amazon CloudFront is a Content Distribution Network or CDN and provides a way for Showit to host your site with great speed results across the globe. Amazon CloudFront is a web service for content delivery and integrates with the other Amazon Web Services to provide an easy way to distribute content to end users with low latency and high data transfer speeds. You can setup your CloudFront settings on the Showit Advanced Hosting panel.

Amazon CloudFront delivers your content using a global network of edge locations. Requests for your content are automatically routed to the nearest edge location, so content is delivered with the best possible performance. When a client requests a web page, Amazon CloudFront determines the best edge location to serve your content. If an edge location doesn’t have a copy of the file that the end user requests, Amazon CloudFront will get a copy and hold it at the edge location so it’s available for future requests.

Currently Amazon's CloudFront has a network of edge locations world-wide including:

  • United States
    • Ashburn, VA
    • Dallas/Fort Worth, TX
    • Jacksonville, FL
    • Los Angeles, CA
    • Miami, FL
    • Newark, NJ
    • Palo Alto, CA
    • Seattle, WA
    • St. Louis, MO
  • Europe
    • Amsterdam
    • Dublin
    • Frankfurt
    • London
    • Paris
    • Stockholm
  • Asia
    • Hong Kong
    • Tokyo
    • Singapore


The use of CloudFront is very advantageous because it comes with great speed improvements. However, the CloudFront API is currently limited because Amazon has not yet provided a way to force the update of content that has been changed. This means that if you overwrite a file on your site, it could take up to 24 hours before those changes will be reflected on your actual website in different parts of the world. For this reason, if you choose to use CloudFront it is recommended that you NEVER overwrite files when adding them to Showit.

When you add a file to Showit and it has the same name as a file that you have already added to your Media Library, Showit asks you if you want to overwrite the file. When you use CloudFront it is recommended that you choose the No option which will create a new unique name. This also means that if you were trying to replace or update a file that was used in many places, you will need to update the content in your site with this new file as it won't be automatically updated.
