A company hosts a website on EC2 instances. They are paying high AWS Data Transfer Out charges because users are downloading large images directly from the EC2 instances. How can the solutions architect reduce these data transfer costs?

Answer options:

Move the EC2 instances to a different AWS Region.

Implement Amazon CloudFront and use the EC2 instances as the origin.

Use AWS Global Accelerator.

Compress the images using AWS Lambda.

How to approach this question

Identify that CloudFront caches data at the edge and reduces origin data transfer out.

Full Answer

B.Implement Amazon CloudFront and use the EC2 instances as the origin.✓ Correct

Implement Amazon CloudFront and use the EC2 instances as the origin.

Amazon CloudFront caches content at edge locations. Data transfer from AWS origins (like EC2 or S3) to CloudFront is free. You only pay for the data transfer from CloudFront to the internet, which is generally cheaper and reduces the load on EC2.

Common mistakes

Thinking Global Accelerator caches content.
