Question

A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple continents. The average volume of data that the company collects from each site daily is 500 GB. Each site has a high-speed Internet connection. The company wants to aggregate the data from all these global sites as quickly as possible in a single Amazon S3 bucket. The solution must minimize operational complexity. Which solution meets these requirements?

Accepted Answer

**Answer A: S3 Transfer Acceleration + Multipart Uploads** satisfies every requirement:

1. **Speed ("as quickly as possible")**: S3 Transfer Acceleration routes data through Amazon CloudFront's globally distributed edge locations, then uses AWS's optimized backbone network to reach the destination S3 bucket. This dramatically accelerates long-distance transfers compared to traversing the public internet end-to-end.

2. **Large file handling (500 GB/day per site)**: Multipart uploads break large objects into smaller parts uploaded in parallel, maximizing throughput on high-speed connections. Parts can be retried independently on failure.

3. **Single S3 bucket**: All sites upload directly to one destination bucket — no intermediate buckets or staging infrastructure needed.

4. **Minimal op
