Which solution meets these requirements?
Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket.
Upload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket. Then remove the data from the origin S3 bucket.
Schedule AWS Snowball Edge Storage Optimized device jobs daily to transfer data from each site to the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket.
Upload the data from each site to an Amazon EC2 instance in the closest Region. Store the data in an Amazon Elastic Block Store (Amazon EBS) volume. At regular intervals, take an EBS snapshot and copy it to the Region that contains the destination S3 bucket. Restore the EBS volume in that Region.
Explanations:
S3 Transfer Acceleration reduces latency and increases transfer speeds for large uploads to S3 from various locations worldwide. Using multipart uploads allows for parallel uploads, further optimizing the transfer of large datasets. This solution minimizes operational complexity by directly uploading to a single S3 bucket without the need for intermediate storage or replication steps.
While this option uploads data to a nearby S3 bucket and uses Cross-Region Replication, it introduces additional operational complexity by requiring management of multiple buckets and the need for data removal from the origin bucket. This method may not be as fast due to the replication process and the overhead involved in transferring data between regions.
AWS Snowball Edge is a good solution for transferring large volumes of data but adds complexity and delay, as it requires physical devices to be shipped and managed. Additionally, the use of Cross-Region Replication further complicates the process by involving multiple steps and regions, which is not ideal for quickly aggregating data into a single bucket.
This approach involves uploading data to an EC2 instance and managing EBS volumes, which adds significant operational complexity. Regularly taking EBS snapshots and copying them introduces delays and does not provide a direct method for quickly aggregating data into S3. The reliance on EC2 for data transfer is inefficient compared to direct uploads to S3.
I have a feeling that the answer is:
Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket.
