A web application hosted on EC2 instances serves a large amount of static media files directly to users over the internet. The AWS bill shows high 'Data Transfer Out' costs. What is the MOST cost-effective way to reduce these charges?
Answer options:
A.
Move the media files to Amazon EFS.
B.
Implement Amazon CloudFront and serve the media files through the CDN.
C.
Use AWS Direct Connect for user traffic.
D.
Compress the files using a Lambda function before serving.
How to approach this question
Identify high egress costs for static media. CloudFront caches data and reduces origin egress fees.
Full Answer
B.Implement Amazon CloudFront and serve the media files through the CDN.✓ Correct
Implement Amazon CloudFront and serve the media files through the CDN.
Amazon CloudFront caches content at edge locations. Data transfer from AWS origins (like EC2 or S3) to CloudFront is free. CloudFront's data transfer out to the internet is typically cheaper than EC2's, significantly reducing overall egress costs.
Common mistakes
Not realizing that data transfer from AWS origins to CloudFront is free.
