AWS cloudFront availability

CloudFront is available to be used through AWS locations. The backbone of CloudFront is the Edge Locations of AWS. So we have the power of CloudFront where ever we have the AWS Edge location.

AWS CloudFront edge locations

Edge Locations works as the backbone of the CloudFront Distribution Network. CloudFront caches the content in the Edge Locations which is accessed by the users making it fast.

For example, when a user requests content then it is rendered from the edge location if it is cached there. But in case it is not then the content is requested from the hosted location and it is then cashed in the edge location.

AWS CloudFront architecture

Now let us check out how CloudFront works. Have a look at the below simple architecture diagram. Then let us discuss more how it works.

AWS CloudFront
AWS CloudFront Architecture
  1. The user makes a request to the CloudFront Distribution Network (CDN).
  2. The call is then redirected to lambda@edge to check the user authentication.
  3. The lambda makes a call to the Cognito user pool to check the user.
  4. Then the user can now access the website after valid authentication is completed.
  5. If the content is not available in that particular edge location then it is cached from the S3 bucket from where it is hosted.

What is CloudFront signed URL?

So, what’s the concept behind this signed URL, let us check it out.

Step 1. The development team configures the application to verify the user and give access to the user as per the payment terms.

Step 2. When a user requests a video from the application the application verifies the user and returns a signed URL.

Step 3. Then that signed URL is used to stream the video. These all things or the steps happen very fast at the backend.

AWS CloudFront S3

CloudFront can be used to render static web pages hosted in the S3 bucket. It’s simple, we have a static webpage in the S3 bucket and we can make that webpage available throughout the globe in a much faster way with the help of CDN, which works primarily at the edge location.
