Question

A media company runs an analytics application on EC2 instances in the us-east-1 Region. The application reads roughly 40 TB of raw video metadata per month from an S3 bucket. The team initially created the S3 bucket in the eu-west-1 Region because that is where the data was first uploaded, but all compute now runs in us-east-1. The finance team has flagged rising data transfer charges. Which action will MOST cost-effectively reduce these charges while keeping the analytics workload unchanged?

Accepted Answer

Create the S3 bucket (or replicate the data) in us-east-1 so the EC2 instances read data within the same Region as the compute.

Answer

Enable S3 Transfer Acceleration on the eu-west-1 bucket to speed up and lower the cost of cross-Region reads.

Answer

Place a CloudFront distribution in front of the eu-west-1 bucket so the EC2 instances read cached objects.

Answer

Move the S3 bucket to S3 Intelligent-Tiering to reduce the cost of frequently accessed metadata.
