Set up a business domain name — Setup CloudFront CDN for Live Events. Part III

Jul 04, 2024

In this tutorial, we’ll explain how you can set up a custom domain name for a CloudFront video distribution.

This tutorial is the third part in our series on CloudFront.

There are quite a few reasons why you might want to attach your own domain name instead of using one that CloudFront has generated for you.

The most important reasons include:


  • Enables custom branding and a professional appearance.
  • Maintains a consistent brand identity across all online properties.

SEO Benefits

  • Improves search engine rankings by using a recognized domain.

User Trust and Recognition

  • Increases user trust by using a familiar and branded URL.
  • Makes the website easier for users to remember and return to.

Flexibility and Control

  • Provides full control over DNS settings, including subdomains and email services.
  • Future-proofs your setup by allowing domain continuity if you change hosting or CDN providers.


To complete this tutorial, you will need:

  • A domain name
  • Access to manage DNS settings for your domain name

If you’re unsure where to find these DNS settings, contact your domain name registrar.

Let’s get started!

First, we’re going to issue a certificate via AWS Certificate Manager (ACM).

Certificates issued by AWS Certificate Manager (ACM) are free to use with CloudFront.

● 1. Open AWS Certificate Manager

Make sure you have default region US East (N. Virginia) selected

Click “Request”

Then click “Next”

On the page that opens, specify your desired subdomain

Click “Request” again

● 2. On the new page that opens, AWS will generate some data to validate your domain ownership via DNS.

Open your domain’s DNS settings and create a CNAME record using the provided NAME and VALUE.

Now it is a waiting game.

CNAME records can take some time to propagate. Typically, certificate validation takes 30 minutes to 1 hour, but in rare cases, it can take up to 48 hours.

If you are setting this up for an event, ensure you allocate enough time for the process.

Once your certificate is validated, you’ll see a green word “Issued” next to it.

● 3. Let’s connect our subdomain name to CloudFront.

Open your CloudFront distribution settings and copy the domain name CloudFront has generated for you.

Go back to the DNS settings. Create a new CNAME record.


Name: subdomain

Value: CloudFront domain name (without https://)

Save your record.

● 4. Update CloudFront settings

Open your CloudFront distribution again.

In the “General” tab, find the “Settings” block.

Click “Edit”

In the page that opens, click the cute little “Add Item” button.

Specify your domain name.

From the Custom SSL certificate dropdown list, select your certificate.

Scroll down and save.

● 5. Important! Ensure you have correct cache settings.

We have a detailed tutorial explaining these settings and why they matter :

Part II — Caching .ts video fragments for HLS

In case you have not set these up yet, please make sure you do so.

Make sure you have a separate behaviour defining the caching of the .ts chunks, and check that your Default behaviour is set to CachingDisabled.

● 6. Test your setup.

To test your setup, turn your instance on. Once your instance is running, open your subdomain in your browser.

You should see Callaba dashboard login page.

Log into the Callaba dashboard. Use your instance ID as the password, with “admin” as the login.

Now all you need to do is create a video player and see if your video is playing without any issues.

If you don’t have an actual stream at hand, you can generate test video within Callaba itself.

Here’s a detailed tutorial explaining how you can set this up :

How to generate Test Videos to test your setups

When you click on the info (i) icon on your Web Player, you will see your subdomain name in the player URL.

Open it and let your video play for a while to ensure the caching is set correctly and the video plays without any issues.

Congratulations. Great job!
